FERMO BREW ACID

The lactic fermentation of sour beers has its own set of challenges. That’s why AEB Brewing has introduced FERMO Brew Acid - a yeast that produces lactic acid during fermentation.

FERMO Brew Acid belongs to the Lachancea thermotolerans species which has been isolated from spontaneous fermentations by researchers at the University of Dijon, France. Its uniqueness lies in its ability to transform monosaccharides in the wort into both lactic acid and alcohol. In combination with a Saccharomyces cerevisiae fermentation the resulting sour beer is rounded and refreshingly acidic.

Add tart fruits such as lemons, limes, passionfruit, pineapples, cherries and strawberries to further compliment the acidity and create a sublime tasting sour.

FERMO BREW ACID
makes brewing sours very easy

• Treat it just like a conventional active dry yeast. Just make sure you check the pH level during fermentation to monitor the acidification.
• With FERMO Brew Acid pH management is easy. The pH drops gradually, typically around 3.3, making it easy to pinpoint the right time to pitch the classic brewing yeast.
• FERMO Brew Acid reduces the risk of cross-contamination since it is neither a beer spoilage bacteria nor Brett strain. It therefore doesn’t require dedicated brewing equipment or specific sanitization routines.
• Any residual presence of FERMO Brew Acid on the equipment will not be able to grow with the presence of conventional brewing yeasts (Saccharomyces cerevisiae), so future batches won’t be contaminated.
• FERMO Brew Acid ferments in a wide temperature range 52°F to 77°F and will not give any off flavors..
• There’s no need for acidified malt in the mash, nor any addition of lactic acid to the wort kettle, or the use of mixed microflora (beer spoilage bacteria and yeasts) during fermentation.
• And it’s fast - you can produce sour beers in a short period of time.
