Lactic Acid Bacteria - Friend or Foe?
Lactic Acid Bacteria - Friend or Foe?
Our upcoming winemaking handbook is almost here and features several new articles, including one on Lactic Acid Bacteria (LAB). Check out the full article on our website or read on for a preview.
ALWAYS PRESENT...
This article was inspired by questions we regularly receive about interpreting microbial analysis. Lactic acid bacteria are easy to ignore as they are omnipresent in wine and wineries; however, they can create off-odors and flavors, even in dry wines.
As seen above, sugars and malic acid aren’t the only compounds lactic acid bacteria can metabolize. They can use citric acid, ethanol, and more.
... BUT NOT ALWAYS HARMLESS
Oenococcus oeni
An ally most of the time, Oenococcus can pose risks if not properly managed after malolactic fermentation.
Lactobacillus spp.
Often most problematic during stuck fermentations or in high pH environments where they can quickly create off-odors and flavors.
Pediococcus spp.
The least well-understood and most often ignored. Until we better understand this genus, Pediococcus presence should raise a red flag.
About
Scott Laboratories Inc. (USA) and Scott Laboratories Ltd. (Canada) are privately held companies specializing in value-added products and services for the North American wine, craft brewing, and distilled spirits industries.
Our predecessor firm (the Berkeley Yeast Laboratory) was founded in the weeks prior to the end of Prohibition in 1933. Our vision is to provide the best customer service to the specialty beverage community. Our mission is to advance the long-term success of the specialty beverage community by providing best-in-class products and services. We believe in education, honesty, and doing the right thing.
Our first products were lab services and yeast. In the years that followed the needs of our industry customers led us first to cellar supplies, then to packaging and finally into processing and bottling equipment. It has been a 80+ year evolution driven by the concept of adding value.
Our current product portfolios include some of the most famous names in the wine, craft brewing, and spirits industries. In some cases, we have our own proprietary products (such as ScottPlus Dry-Steam Natural Cork and ScottCart filters) while in other cases we work with the industry's leading vendors and suppliers. You can check out virtually all of our offerings on our website at www.scottlab.com.
As of 2020, our companies have 90 employees. Our headquarters are in Petaluma, California and Pickering, Ontario. In addition, Scott Laboratories USA has locations in Healdsburg (Sonoma County) and Paso Robles.
