The company's Pekin, IL wet mill operates a continuous beer fermentation process, producing more than two million gallons of beer per day. This process uses a corn starch media and distiller's yeast of the saccharomyces cerviseae classification. Our plant microbiologists closely monitor the fermentation process to ensure clean, healthy fermentation without the use of antibiotics. The beer and distiller's yeast stream is transported via pipeline directly to Aventine's distiller's yeast plant. The distiller's yeast is removed from the beer stream and immediately processed into a growing variety of products for use in animal, pet and human food, and fermentation applications.
