90% Ethanol for COVID-19 disinfection available
23 March, 2020

As wineries are considered essential businesses during the Covid-19 epidemic, it is essential to protect employees and prevent the further spread of the virus. Disinfecting common surfaces is an absolute must! Ethanol is a highly effective "people friendly" surface disinfectant when used at the correct strength. VA Filtration USA has 90% by strength grape based ethanol available for immediate shipping or collection. 

How to use ethanol for disinfection?

We would recommend the following protocol for disinfection:

Dilute 90% ethanol down to 70% strength by adding water (7 parts 90% ethanol to 2 parts water). The dilution lengthens the evaporation time of the mixture, allowing sufficient time for the ethanol to disinfect the surface (60 seconds minimum contact time).

Add the mixture to a spray bottle and spray on surfaces ensuring complete coverage and wait for a minimum of 60 seconds. Wipe surfaces with a clean dry cloth if needed.

How effective is ethanol against Covid-19?

“Ethanol at concentrations between 62% and 71% reduced coronavirus infectivity within 1 min exposure time by 3.0–4.0 log10,” according to investigators with University Medicine Greifswald and Ruhr University Bochum in Germany whose study ran as an article in press in the Journal of Hospital Infection (JHI)


What the above means, is that 99.9% - 99.99% of the effectiveness of the virus is reduced in 60 seconds when in contact with 70% ethanol.

Can it be used on hands?

Yes. It is safe to use on exposed skin but can lead to drying of the skin. Use a personal hand cream to keep skin from drying out after using the spray.

To purchase, simply e-mail or call us. Note that excise taxes may apply when using the ethanol as a disinfecting agent.

Filtration Technology Focused on Wine Quality
14 February, 2020

For more than 18 years, VA Filtration has distinguished itself as a leader in providing rapid, effective, unobtrusive and energy efficient filtration solutions to wine industry professionals around the globe.

Specializing in crossflow systems since 2005, VA Filtration has mastered the art of utilizing spiral wound elements to deliver an extremely gentle filtration process designed to protect the integrity and quality of wine.

“Our systems have always focused on quality,” confirms VA Filtration CEO Bryan Tudhope. “Wine tastes better after crossflow than before.”

Mobile crossflow unit

Consistently on the cutting edge of new technologies, VA Filtration now also offers silicon fiber, a hard, porous material used in the construction of the filtration membrane itself, to enhance the rate of filtration per square meter of surface area.

“Traditional spiral wound membranes filter about 15-20 liters per square meter an hour,” explains Tudhope. “With silicon fiber, it increases to 45-60 liters per square meter an hour. That’s more than three times the flow rate per m2 of membrane surface area.”


Tudhope points out that the increased flow rate from silicon fiber is a huge benefit to wineries filtering bulk wines at high volume. He notes that the material has superior thermodynamic properties, a membrane life that is three to five times longer than polymer systems and reduces overall water and chemical use for system cleaning.

VA Filtration offers multiple service options with maximum flexibility to accommodate all winery filtration needs, including:

  • Mobile service – a full range of crossflow machines are available for onsite filtration, offering guaranteed service with expert technicians.
  • Medium and long term rental – VA Filtration offers all of its crossflow equipment on one to three month or one to five year rental terms. System stays on site at winery on a pay-by-use basis.
  • Daily rental – ideal, cost-effective solution for small lot winemaking. Two options for rental available in 110V single-phase configurations.
  • Machines for purchase – VA Filtration designs and manufactures systems of any size and configuration to address specific winery site and process requirements. All models have been extensively tested in the field.

VA Filtration systems are proudly designed, manufactured and operated in American Canyon, USA.

New Multi-Pronged Smoke Taint Removal Process Patented
03 January, 2020

Climate change presents real challenges to wine producing locations when wildfires strike where wine grapes are grown. Essentially sucking in the smoke compounds floating in the air through their skins, wine grapes are then able to pass this into the wine being made. VA Filtration USA offers a brand new process, removing not only the free taint creating the smoke aromatics, but also the bound taint from affected wine, eliminating the “rebound” effect.

VA Filtration currently holds US Patents* for free taint removal, as well as the nanofiltration-based processing of VA reduction. Working last spring to help Napa Valley vintners remove taint from the 2017 fires, VA Filtration’s newest and recently developed three-pronged process is now in trials in Napa, Sonoma, Mendocino and Lake Counties in Northern California. Providing scientific results by using a combination of proprietary MWCO membrane elements and adsorption columns, they are able to reduce the glycosides considerably per filtration pass. The following example analysis of a wine processed using this new method indicates the new level of reduction achieved in the first pass through the system (all analysis performed by the AWRI):

Smoke taint removal data table

The glycosides (Gentiobiosides and rutinosides) are the culprits of the bound taint. This new process lowers their levels significantly at each pass through the process. As a benchmark, non-tainted oaked cabernet sauvignon shows the following peak baseline numbers (as provided by the AWRI baseline survey for Australian Cabernet Sauvignon wines):

Syringol Gentiobioside4.5
Methylsyringol gentiobioside1.1
Phenol Rutinoside4
Cresol Rutinoside4
Guaiacol Rutinoside7
Methylguaiacol rutinoside4

The old process often included a pre-enzymatic treatment on the wine two to three weeks prior to the action. Then came a crossflow filtering of the wine prior to taint reduction, then the taint reduction process itself. Finally, some winemakers opted for a final concentration of the wine post taint reduction using UF.

With their newest process, the wine undergoes an on-premise, three step procedure. To start the process, your wine goes into a membrane system, which separates the liquid into two parts, a retentate stream and a permeate stream. It is the permeate stream which contains both the bound and the free form of the smoke compounds. The permeate stream is then sent through an adsorption column, where the free form of the smoke aromatics are reduced. The same permeate stream then goes into a secondary treatment column, where the bound form of the smoke taint is reduced (glycosides & rutinosides). Depending on the level of taint, VA Filtration experts can recommend the number of passes which will give you the best results for your product. Wine with lesser taint may undergo fewer passes through the system, while wines with heavier taint may need up to five passes or more. Each client only need contract for the number of passes that suit the level of taint.

Capable of processing 1500 gallons per hour, VA Filtration has the bandwidth to process anywhere from one barrel to large amounts. Trial tests are available on amounts from one gallon up, but results are more conclusive the larger the trial sample, providing a great benchmark for testing.

VA Filtration is a mobile wine service and equipment manufacturing company, with patented procedures. VA Filtration specializes in all forms of membrane processing systems.

One Man’s Idea Becomes Leading Filtration and Remediation Solution for Wine Industry
11 December, 2018

By Elizabeth Hans McCrone

VA Filtration USA, a 2018 WINnovation Award Winner

For Bryan Tudhope, the CEO and founder of VA Filtration USA, solving problems through chemistry has always been second nature.

It started back in 1998 when he was a chemical engineer for water purification systems in South Africa. An engineering colleague asked him if he knew how to remove vinegar from wine and he decided to give it a try.

The method Tudhope developed worked so well, he started VA Filtration South Africa in 1999 to focus on vinegar removal for wineries in the Western Cape. 

Two years later, he and his two partners decided to expand the business to the USA.

In 2002, VA Filtration USA was officially born and it has evolved into the leading provider of filtration and remediation services for the North American wine industry.

“I started with just one machine, running around California and couldn’t keep up with demand,” Tudhope recalls. “I hired a tech to help me, and the business just grew. It turns out a lot of the hardware used to remove vinegar can also be used to address other problems.”

Bryan Tudhope

The ’other problems‘ Tudhope refers to include VA/EA reduction, Brett character reduction, green character reduction, cork taint removal, smoke taint reduction, alcohol reduction, and CO2 addition/O2 removal.

Tudhope’s mobile system also provides wineries with crossflow filtration, lees filtration, and a system known as Sweetspotter, a rental unit developed specifically to address problems in small lot wine production.

“Our systems are capable of handling a lot of different operating procedures,” Tudhope explains. “We have different membranes and other elements that we load into the systems for high level filtration, as well as to the handle the critical, second stage processes that capture exactly what it is that you want to eliminate from the wine.”

The benefits of Tudhope’s technology are numerous. Among them, he lists:

  • Zero oxygen pickup
  • Filtration to .2 microns, resulting in complete removal of bacteria
  • No DE needed in the newest Dynamic crossflow system
  • No heat pickup

“Everything is mobile, mounted on trailers so that we can take it from facility to facility,” Tudhope adds. “We’ll take it to wherever you want, for whatever it is you’re trying to remove.”

VA Filtration USA is one of the winners of the 2018 WINnovation awards. Introduced by the Wine Industry Network (WIN) in 2013, the WINnovation awards were set up to honor companies that have developed groundbreaking products or practices contributing to the advancement of the North American wine industry.

VA Filtration USA was selected this year because of its commitment to designing, manufacturing and operating all products in-house, in the U.S. The company was also lauded for its outstanding technological achievements and its overall positive impact on the quality of winemaking.

When asked to describe the philosophy behind what he and his company have done to receive recognition as a leading wine industry innovator, Tudhope is very clear that it comes down to two basic principles.

“Number one is that we pride ourselves in offering excellent service in terms of the processes we deliver,” Tudhope affirms. “A good wine is a winemaker’s pride and joy. If it’s (filtration, remediation) not done correctly, you can really mess that up. But done correctly, the full effect of the wine comes back out.”

“The second thing,” he continues, “is really listening to what winemakers need, and even figuring it out before they need it … that’s what drives the innovation.”

Tudhope, who has been working with filtration and remediation for 18 years, did not know that VA Filtration USA was under consideration as a WINnovation Award winner.

“It’s exciting, I had no idea. This is quite a surprise,” he admits. “It’s nice for the staff too, being able to share this with them. For us, seeing what you’re able to achieve just by removing a compound – and being able to offer that service and repeat it day after day – it’s really important.”

BENCHSPOTTER - Taint removal goes micro
05 November, 2018

VA Filtration USA is proud to introduce its latest offering - the Benchspotter! 

The Benchspotter is a laboratory scale unit capable of trialing multiple membrane based processes available from VA Filtration USA.  Weighing in at only 60 pounds and with a small foot print and removable tank, this unit is an ideal fit in every lab wanting to tweak wines for improved quality.  The Benchspotter is able to run the following process solutions:

New Precision Carbonation System from VA Filtration
23 February, 2018

VA Filtration has just introduced its new precision carbonation system at the Unified Symposium. The PreCarb system, called the Carbonator, is a diffusion-based CO2 addition system that allows the winemaker precise control over the level of CO2 in wine, cider, or beer.

“The biggest difference this machine offers is the precise level of CO2 you desire without beating up the wine,” says Bryan Tudhope, President and CEO of VA Filtration. “You don’t lose the unique aromatics of the wine by rolling or sparging tanks and no oxidation occurs in the closed system.”

The system measures the amount of CO2 in the wine as it exits the machine using infrared technology, based on a level that is set on the control panel by the winemaker. The Carbonator can also be used to remove CO2 and dissolved oxygen from the wine when operated in a vacuum phase.

It is completely automated, so no sparging or frequently checking numbers is required. The machine also operates in a closed system so no loss of aromatics or outside oxidation occurs during the process.

The Carbonator is an addition to VA Filtration’s multitude of services to directly add quality and value by gentling removing undesirable components or taints from your wine on site. Operating mobile services in most of the best wine regions in the world including USA, Australia, Europe, and South America; VA Filtration not only brings the service to you but promises to do so in a fast, efficient, and quality-focused method.

VA Filtration is a global leader in the design and manufacture of membrane-based wine processing equipment. With more than 16 mobile and rental machines available and more than 8 service offerings, VA Filtration has the largest and most diverse fleet of mobile wine processing equipment.

16 January, 2018

Are you lookign at freshening up white wines prior to bottling?  

Are you looking to add CO2 to your wine at a controlled level prior to bottling?

Would you like to do this without using an archaic sparging process that strips the wine of volatiles?

Would you like to remove dissolved oxygen with or without adjusting CO2 levels?  

In-line Carbonator

If you answered yes to any of the above questions, then VA Filtration has the system for you.  We have designed and manufactured, in the USA, a carbonation system that makes use of a diffusion process to add CO2 to wine/cider/beer or any beverage.  By utlizing in-line carbon measurement, this system can accurately control the levels of CO2 being added to the beverage.  With flow rates from 5 to 30 gpm, the system can easily keep up with most bottling lines and with a simple PLC set and forget, the system will adjust the level of CO2 to your desired set-point value without batting an eyelid.  No more guess work required! 

  • Flow rate : 5-30 gpm
  • CO2 addition : 0.5 to 7 g/l possible
  • Control : Automated PLC control
  • CO2 in-line monitoring : Yes

You can purchase or rent the unit as required.  Just give us a call to trial it out!

Smoke Taint and the handling of wine that may be impacted
18 October, 2017

To our employees, friends, customers and vendors impacted by the recent wild fires, we are grateful to be part of such a strong and unified community.  The losses incurred by some are unimaginable and our hats go off to the outpouring of help, love and support from all during these difficult times. As a company involved in the removal of taints from devastating events such as these, we want to make sure that the information that you are seeking is relevant and honest.  If you have any questiosn at all related to smoke taint, please do not hesitate in calling on us. 


This article serves to present the facts regarding smoke taint and offers potential solutions for dealing with this problem based on the most recent information available to the industry. For those wanting more information on the exact mechanisms of smoke taint adsorption, detection and handling of the fruit, there are some great links at the end of this article. 

What is Smoke Taint?

Smoke taint is made up of numerous compounds present in smoke that in simplistic terms enters the fruit/wine via the skin. The historical markers for smoke taint were generally Guaiacol and 4-Methylguaiacol. Guaiacol, however, is naturally present in some grape varieties, especially Syrah (8), and 4-methyl guaiacol is also present in wines aged in oak barrels, which complicates their use as markers for smoke taint potential. Latest research suggests other components being present including o-cresol, m-cresol, p-cresol, syringol, 4-methyl syringol, 4-ethylguaiacol and others (Hayakasa et. al. 2010, J. Agric. Food ; Parker et. al. 2012, J. Agric. Food). These compounds are now also monitored as additional indicators of smoke taint risk. It must be noted, however, that these markers do not necessarily indicate the extent of the problem but are used to identify a potential issue with the fruit. Often smoke taint isnot detectable based on a sensory evaluation of crushed fruit. 

Smoke taint compounds are bound to the glycosides within the juice via a glycosidic bond. During fermentation and aging, these gycosides break down and relaease the volatile smoke taint phenols into the wine, which are then easily identifiable via a sensory evaluation of the wine. Interestingly enough, if one was to take a measurement of the guaicaol concentration before, during and after fermentation, one would see a steady rise in these volatile phenolics. This was evident in 2009. These glycosides also continue to break down through hydrolysis at wine pH as the wine ages. This is one of the suggested reasons as to why the taint comes back when a wine is processed too soon for phenolic taint removal. 

The levels of taint are typically much higher in red wines than in white wines. The evidence points to a concentration of the smoke compounds within the skin of the fruit. Since red wine requires extended skin contact, it is reasonable that these wines would see higher levels of taint. 

Treatments for Smoke Taint in wine

It has been shown that membrane treatment in combination with adsorption is an effective means of dealing with smoke taint – see Fudge, A. L.; Ristic, R.; Wollan, D.; Wilkinson, K. L. (2011) Amelioration of smoke taint in wine by reverse osmosis and solid phase adsorption. Aust. J. Grape Wine Res. 17 (2): 41-48. 

The experience gleaned by VA Filtration USA from 2009 fires was invauable in dealing with the issue of smoke taint. At one facility, where over 500,000 gallons was treated in multiple lots of wine, approximately half of the wine treated showed no sign of smoke taint within one year of processing. The other half showed smoke taint at levels that were a lot lower than the original levels but were still detectable! There is also anecdotal evidence that indicates treatment is more effective later in a wines life. This might be due to a slow-down in glycoside breakdown as the wine ages. Theoretically at that point, the process of smoke taint removal would be more effective and limit the chance of a reoccurrence. There is no hard evidence to back this theory, but it was definitely a trend when dealing with the 2008 harvest smoke taint issues. 

Some Suggestions regarding aging

If you want to barrel age the wine, I strongly suggest using neutral oak barrels for aging purposes. Toasted oak barrels add a smoky component to the wine that exacerbates the perceived levels of smoke taint.  We do not have any evidence or knowledge of barrels being contaminated with smoke related phenolics.

For those of you with no alternative but to get the wine to bottle and on the shelf, treatment will be necessary early in the wines life and bottle aging might not be possible if this is the case. 

The Treatment Process

The most effective process of treating smoke tainted wine involves the use of VA Filtration patented nanofiltration membrane in combination with adsorption process. Typically the wine needs to be passed through this process at least 2-4 times, depending on the severity of the problem. In 2009 wine required an average of 3 passes through the system, although some wines took 6 or 7 passes to reach undetectable levels.

17 August, 2015

With all the wild fires about, the question of smoke taint is on every winemakers lips.  Is it in the fruit?  Will it affect my wine?  How do I remove it?  Based on 2008 experience, excessively tainted fruit can make some very ashy, astringent, bacony wine (think of drinking red wine around a smokey camp fire).  If your wine is contaminated, there are options for dealing with the issue.  

How do I deal with smoke taint?

Juice Stage

The BIG question is how to deal with this problem.  There are several helpful tools in dealing with it, but no "magical" cure.  One option is to flash the resently harvested fruit (reds only) to remove as much smoke taint from the skins before it has a chance to integrate with the juice.  It is suspected that the smoke taint is concentrated in the skins of the berry due to some interesting observations of the contamination process in 2008.  Juice samples that showed little to no sign of smoke taint in 2008 resulted in highly tainted wine after ferrmenattion and whites showed lower levels of smoke taint due to limited skin contact.  Since the flash process wasn't used much in 2008 to deal with the issue, we have limited knowledge on the success of this processing option, but if it reduces the guaiacol levels by more than 50% right off the bat, then you are half way through dealing with the issue.  

Wine Stage

During fermentation, the level of smoke taint increases as the sugar is broken down during the fermentation process.  This is due to the smoke compounds being bound to the glycosides within the liquid.  As these glycosides break down, the smoke compounds are released.  To find out if wine is contaminated, a guaicaol analysis will prove its presence and show the level of taint.  This level can range from 4 ug/l to as high as 200 ug/l. Note this analysis needs to be done before any oak products are added to the wine.    VA Filtration was able to successfully treat wines with Guaiacol levels of up to 80 ug/l, but beyond that, the results can vary dramatically.  It is also known that the treatment has a 50% long term success rating.  In around half the wines treated in 2008/2009, the smoke taint returned within a year.  The levels were diminished, but it was definately there.  This return affect is again due to the break down in the glycosides, where the smoke taint compounds are attached, as the wine ages.  A "fire" sale might be necessary if it is found that wine has smoke taint.  

The Treatment Process

VA Filtration has the only patented process for dealing with smoke taint.  Using nanofiltration in conjunction with phenolic removal media, the guaiacol and related smoke taint phenolics are removed from the wine gently and efficiently.  We successfuully treated over 2 000 000 gallons of smoke tainted wine in 2009.  This year we have dedicated machinery designed for rental or servicing in case of smoke taint.

VA Filtration offers its trialed and tested Ultrafiltration process for the removal of color and bitterness from heavy press juice fractions.  Typically used in Pinot Grigio, it has also found use in other white varietals.  

Benefits are two-fold - if the heavy press fraction is too dark it is typically discarded or used in lower cost blends.  VA Filtrations Ultrafiltration process allows for the recovery of up to 80% of that press fraction at the same quality and higher than the free run or low pressure fraction.  The concentrated product can also be used as co-factor in other fermentations.  Win win situation.  

The success of the process does depend on the pre-filtration of the juice.  The cleaner the juice the higher the recovery.  We recommend rotovac or filter press followed by crossflow.

The MEMSTAR Process advantages for alcohol reduction
08 May, 2015

With the recent acquisition of Memstar, VA Filtration USA is making on-site alcohol reduction easier than ever.  The patent pending MEMSTAR process is the highest quality process available for on-site ethanol reduction.  The process in a nutshell is the removal of low boiling point ethanol via a membrane contactor on permeate and NOT wine.  The process uses a strip water which carries the removed ethanol away for distillation off site.  The quality of this process is unsurpassed by anything else on the market today. 

What is a Membrane Contactor?

A membrane contactor is a hydrophobic membrane that allows the passage of vapor but not liquid.  Think GORETEX ski jackets.  These keep one dry in the rain but allow water vapor from perspiration to escape keeping you dry.  Exact same technology, except ethanol is the vapor! 

How does the Memstar process compare to other on-site options out there?

  1. Highest quality- The Memstar process removes the ethanol from the PERMEATE in the membrane contactor.  Other companies offering this service send WINE directly through the membrane contactor which results in excessive aromatic losses.  The strip water is also often tinged pink, which means that wine is being lost within the contacting process or the contactor has hydrophilic pockets.  Not good!
  2. Faster process- because the Memstar process removes the ethanol from the permeate, it becomes possible to use temperature to substantially increase the removal rate of the ethanol.  The boiling point of ethanol increases with an increase in temperature.  This means more vapor generation and removal is possible through the membrane contactor.  The Memstar process uses this advantage due to the permeate being passed through the contactor and not the wine.  Competitors can't offer this advantage since they would be applying heat directly to the wine. 
  3. No wet out - The weakness when it comes to membrane contactors is that they can become hydrophilic over time.  This is due to the components within the wine causing this wet-out phenomenon and results in the passage of water into the wine and vise versa.  Because the Memstar process only sends permeate through the contactor, this is not an issue. 

VA Filtration is making the option of utilizing this service easier than ever.  We have lease programs that allow wineries to use the machine over a pre-determined period of time without making the substantial investment of owning the machinery.  We have many other options too of providing this technology, just give us a ring or send an e-mail to!

MEMSTAR - The gentlest option for on-site alcohol reduction
13 February, 2015

  • Do you have a DSP license?
  • Would you like to have the ability to reduce alcohol in wine on-site? 
  • Do you want a system that focuses on wine quality and efficiency?  

With the US patent pending MEMSTAR system, on-site alcohol reduction for existing DSP facilities is an ideal option.  The MEMSTAR system is far superior to other on-site alcohol reduction methods due to the fact that it removes the ethanol from the permeate AND NOT FROM THE WINE.  By running wine cirectly through the osmotic distillation process on other systems, aroma loss is huge.  With the MEMSTAR system, aroma loss is minimal due to the wine first being separated via a nanofiltration membrane.  The MEMSTAR system also gets the ethanol content of the strip water above 7% and higher theerby minimizing water use.  

We have options to supply complete integrated systems or machinery that can be added to already existing wine concentrators.

Due to some enormous wildfires this year, the lingering smoke might have left its mark on the grapes.  How will you know if you have smoke taint?  If there are some smokey aromas present in your wine after fermentation then a simple test showing the levels of Guaicaol present in the juice/wine BEFORE oak addition will indicate the level of smoke taint present.  

Is there anything you can do?  Well yes - VA Filtration can help.  We offer the ONLY mobile service in the USA based on our patented nanofiltration process designed for the optimum reduction of smoke taint compounds from wine.  

Will the taint come back?  Well that depends on a number of factors.  In some cases yes, and in some cases no.  We learnt a great deal on dealing with smoke taint from the 2008 harvest and that knowledge has been transferred into our process.  


VA Filtration has developed a 180 gal/hr crossflow filter that can be rented for the filtration of small lots of wine.  This is THE ONLY RENTAL CROSSFLOW  available on the market today capable of operating off 110V single phase power.  It is extremely simple to operate and very robust. Give it a try today!

Have you ever wanted to see what your wine would look like with 2%, 5% or 10% concentration?  

Ever wanted to carry out your own alcohol Sweetspot trials?  

Well now you can - on as little as 1000 ml of wine using the FOSMOS single use pouches and all for only $6.00 per pouch!  It has never been simpler.  The pouches use forward osmosis technology along with a cocnentration gradient to allow water and ethanol only to cross the membrane barrier - leaving the color/tannin and phenolics behind.  

Just drop the pouch in a 1000 ml of wine and within 4 hours your wine will be 10% more concentrated.  Then calculate your concentration level  by volume measurement or weight and blend back with the original wine creating your ideal Sweetspot concentration.  Ideal for the 2011 harvest.

Once you have dialed in your concetration level, VA Filtration can concentrate larger volumes of wine legally using Ultrafiltration on either our full scale equipment or our Sweetspotters.  

Give us a call now - we have pouches in stock ready to go.

All of our services use a technology that minimizes the handling of the wine and assures maximum efficiency during processing.  The key to our technology is the diaphragm pumping system involved in moving and pressurizing the wine.  Other suppliers make use of multistage centrifugal pumps that shear and heat the wine and force them to operate their equipment at single pass efficiency of less than 10%.  That means only 10% of the VA/4EP will be removed on a single pass through the machine.  VA Filtrations full scale continuously supervised equipment operates at a target removal rate of 30% of the taint per pass - meaning less handling of the wine overall.  This same technology carries over into our crossflow systems - where we minimize re-circulation of the wine as much as possible.  

VA Filtration is able to design and manufacture as well as offer a mobile service for the following:

  • VA Reduction
  • 4EP/4EG Reduction
  • Pyrazine reduction
  • DES Reduction
  • pH Correction
  • Stabilize wine with respect to tartrate precipitation
  • Crossflow Filtration
  • Alcohol Reduction
  • Wine Concentration
  • Small lot treatment options - The Sweetspotter

Give us a call.  We are still the most competitive service company on the market today and all of our systems are designed and manufactured in the USA.

The 2011 harvest left some wines a little short on concentration and high in methoxypyrazine characters (green, vegetable character). It has recently become possible to measure IBMP in wines in the US - which is great to see what levels are present.  Sometimes these levels can be 5 times threshold - which makes reduction very tricky.  It is however possible to lower the levels of IBMP using membrane technology, but considering the intensity of processing required on the high IBMP wines, this is not always practical and can do more harm than good.

VA Filtration has done a lot of work over the last 6 months on these greener, thinner wines.  The results have been spectacular - with intense vegatative character disappearing almost entirely.  The treatment method involves a combination of technologies - including IBMP reduction and/or concentration and/or addition of our pre-selected Predel tannins. 

We recommend trials be carried out at your winery by using the Sweetspotter system and some sample tannins available through VA Filtration.  The Sweetspotter is able to both lower the IBMP levels as well as concentrate the wine.  Once the removal/concentration is complete - our enologist, Milan Vujnic, is able to help you with the addition trials for further masking of the green character.

As a side note - the concentration of wine is perfectly legal according to TTB codes and regulations.  You are essentially separating the wine into a high color/low color fraction, with the high color fraction being the concentrated portion of the wine.  The low color fraction is separated out and kept separately as wine.  You have to use ultrafiltration membrane technology for the process and stay under certain operating pressures.  VA Filtration will ensure all treatment follows the TTB codes.  

Give us a call and we would be happy to help you get the best out of your wine.  

Buy your own VA Filtration system - Made in the USA!
15 March, 2013

VA Filtration is a US based manufacturer of all systems related to membrane processing.  

We currently manufacture reverse osmosis, nanofiltration, ultrafiltration and microfiltration systems for the wine industry right here is the USA.  Current models include our smallest manually operated single barrel Sweetspotter systems for VA/Taint removal through to fully automated crossflow systems for bottle ready filtration and everything inbetween.

We are also able to offer distillation columns for ethanol removal from permeate.  

We recently added 4000 ft2 of manufacturing space in American Canyon to keep up with our current back-log of machinery on order.

If you are in need of membrane processing equipment or distillation equipment, give us a ring.  We are able to custom manufacture anything you may need or think you need.

VA Filtration manufacturers a range of wine crossflow filters that are easy to use and even easier on your budget.  Our systems utlize spiral wound membrane technology - so there are never any integrity failures from broken straws!  The membrane elements are manufactured in the US and are 1/3rd the cost of our closest competitors to replace.  

All systems are manufactured in American Canyon using US sourced components where possible.  We supply manual, semi-auto and fully auto systems.

Our latest design is a manually operated 2 membrane system (CF8-2-200M) capable of filtering up to 200 gal/hr of wine.  Ideal for the smaller winery and at only $22 500.00, it will fit most budgets.  Our 6 membrane semi-auto system sells for $65 000.00.

The technology used in the above systems is the same as that of our mobile service.

Do you know how much value is in your lees?  Let's say you had 1000 gallons of accumulated lees over the course of harvest.  At 80% recovery, this equates to 800 gallons of wine.  Even if you got $8.00 per gallon for this wine, thats $6400.00 worth of product!  Yet you are willing to sell this stored lees for $1.00 per gallon to lees recovery companies???  Makes no financial sense at all. 

The cost of lees filtration averages between $1.00 and $1.80 per gallon of product recovered.  Whatever you recover can be made into decent wine and sold on the bulk market or used in your current programmes.  Thats what the lees recovery companies are doing.  They take your lees, filter it, blend it and sell it on the bulk market.  

Worried about the quality? Keep it chilled until we can get to it, then just process the recovered wine/juice and process it as a separate lot.  

Give it a try!  Its worth the effort.

HAR 17 is a blend of bayanus and cerevisiae.  This yeast is ideal for the fermentation of high brix fruit and or re-starting stuck fermenations.  It is tolerant to 17% alcohol.

It is also recommened for the fermentation of Chardonnay due to the naturally occuring high content of mannoproteins.  

ONLY : $30.00 per 500 grams OR $490.00 for 10 kg

The TTB recently approved the use of CMC's for the tartaric stability of wine.  Our CMC (carboxy methyl cellulose), called STABICELL, is typically added to white wine in the form of a 21% strength liquid (STABICELL 21LV) or as a micronized powder at 98% strength (STABICELL Micro).  This product is not suitable for red wine tartaric stabilization or for white wines that are not protein stable.

STABICELL acts as a protective colloid.   It hinders the formation and growth of tartrate microcrystals, thus preventing the precicipation of tartaric salts, potassium bitartrate or calcium bitartrate.   

With a cost of treatment as low as $0.012 per gallon, the ENERGY and financial SAVING over traditional methods IS ENORMOUS.  

STABICELL samples are available for trial purposes from our offices.

Current methods of reducing alcohol on-site (assuming you have a DSP license) involve the use of large volumes of water to remove alcohol from permeate or wine.  This water - along with the ethanol - ends up in ponds or municipal waste systems or requires significant transport costs to get it back to a distillation facility.  About as far from sustainable practices as you can get!

Well what if you could remove the ethanol from your wine at 170 proof and eliminate your waste water problem as well as transport issues?  


VA Filtration is proud to introduce the first of its kind mobile vacuum distillation system capable of reducing ethanol on-site and recovering that ethanol in the form of high proof.  The system is completely self contained and operates off electrical power only.  No need for gas boilers or the like.

Got strip water with 8% ethanol content?  We can treat that too!


Average removal rate of ethanol from wine : 1000 gal/hr lowering from 15% to 14% ethanol. 

Average volume of 85% ethanol produced per hour : 15 gal

Power requirement : 2 x 480V, 30 amp outlets

Impact on the environment : Zero waste discharge

Our system will be operational in June 2012.

The FOSMOS is a forward osmosis membrane pouch designed to remove water and alcohol from wine on a laboratory scale.  Simply place the pouch in a flask of wine on the bench and it will draw in water and alcohol through an osmotic pressure differential process. 

You can draw as much as 250ml of water/alcohol solution from the wine per pouch.  The concentrated portion of the wine can then be back-blended with the original wine to make up any number of wines with different concentrations.  This is an invaluable tool for winemakers - especially after the 2011 harvest.

The FOSMOS is available from our offices for $6.00 each.  

PYRAZINE - IBMP & IPMP Reduction in wine
06 January, 2012

PYRAZINE Reduction

Yes we can remove Pyrazine or herbaceous/vegetable qualities that are present in wine.  Our patented process utilizes nanofiltration technology coupled with adsorption.  The success of the process depends on starting levels though.  Since the threshold for IBMP is 2 ng/l and common levels are in excess of 8 ng/l, getting to threshold requires multiple passes.  As usual you can trial with the Sweetspotter to be sure this is going to work for you.

NEW and REVOLUTIONARY method of juice/must concentration
20 September, 2011

 FOSMOS* for Juice/Must Concentration

VA Filtration USA introduces the FOSMOS*.  A new and innovative way of concentrating juice or must without pressure!.  The FOSMOS is a reusable or single use pouch that can be added to juice or must to raise sugar content.  The bag uses the principal of forward osmosis to draw in the water from the juice.  NO PRESSURE is needed.  It works at ambient temperature and pressure conditions - net result - the gentlest form of concentration EVER!

FOSMOS* for laboratory de-alc trials - a must for any wine laboratory

The pouches can be used for de-alc trials in the laboratory.  Simply add 750 ml wine to the pouch, seal and submerge in a draw solution.  After 6-12 hours the wine will be more concentrated with a lower alcohol content. Simply decant, add back water to the original volume and use the final wine for Sweetspot trials.  Can reduce the alcohol in wine to less than 1% if necessary.  

 We are excited to release FOSMOS to the US wine industry first.  This product is not available anywhere else in the world at this point.  Just another tool for winemakers to increase wine quality at the end of the day in keeping with our motto that gentler is better!
