The new FlexStaves system of winemaking is here!

And a question you've been asking is 
"How much oak should I use?"

Answer: Each FlexStaves bundle contains a selection of staves that, regardless of number of staves, is one barrel equivalent - 225 liters or 59 gallons.

But we make it easy to determine the number of bundles needed! Just click on the FlexStaves Calculator Button on the FlexStaves Page to pull up our FlexStaves Calculator where you can adjust the setting to get the correct amount of stave bundles required for your desired result (as shown below)!

How To Incorporate FlexStaves into Your Winemaking for a True Oak Barrel Replacement

Setup:

Each stave bundle pack is tied together with a stainless steel strap. Each bundle has the same level of oak to wine contact as compared to using a new 59 gallon barrel. The number of bundles used is a function of tank size and the percentage of new barrel equivalent the winemaker desires. As the staves absorb the wine, they sink into the tank over time. Bloom during extraction is normal, mixing prior to sampling is essential.

Cellar Recommendations:

1. Preform all normal barrel operations for the Flextank system.
2. Leave no headspace.
3. Perform regular chemical tests.
4. So2 as needed.
5. Strictly monitor of microbiological conditions.
6. Rack as needed.

Recommended Time of Contact:

Minimum 4-8 months, to be monitored by tasting. To achieve barrel results, longer aging is often needed.

Additional notes:

1. Always off-gas a fresh fermentation. Venting might be necessary.
2. On first fill, Flextanks will have a resting and settling period. The tank will stretch during this period, about 1-2 weeks. This will allow the tank to achieve equilibrium with the volume of liquid. Because of Flextanks’ engineering NO additional liquid is passed through the walls and topping is rarely needed. Topping will occur in the case of sample replacement or oak removal. In this case, add wine as needed.

More FlexStave FAQs:

Will adding FlexStaves to my wine add micro-ox? 

Yes, about 3-4 mg/L/year. This is notable to the total with your Flextank Micro -Ox.

Is there a way to weight down the FlexStaves?

No, Flextank is a barrel replacement and always should be topped off. When this is followed your FlexStaves are 100% submerged. Bloom or stratification is normal in any vessel and mixing to obtain the true sample is part of good cellar practice. 

Will FlexStaves sink to the bottom in time? 

Yes, expect about 4-8 months for this to occur. Your pack will come with a stainless-steel band to gather them. You will need a harvest rake or other sanitary device to pull them out. Otherwise, drain and remove on regular racking.  

If I find after several months or less the wine has enough oak, can I remove and reuse? 

Only if you are going to transfer into wine ASAP. Microbial populations will take over spoil any oak product in the cellar. In general, FlexStaves are one time use.
