Premium Lager Yeast for Professional Brewers

High-Performance Lager Yeast for Clean, Crisp Fermentation

For breweries aiming to elevate their lager beer lineup or experiment with new seasonal brews, The Brewing Science Institute (BSI) offers a curated selection of premium lager yeast strains to meet your exact needs. Our strains—primarily Saccharomyces pastorianus and cold-tolerant hybrids derived from S. eubayanus—thrive at traditional lager fermentation temperatures between 45–55 °F, producing clean, crisp, and highly drinkable beers with minimal ester production. This slow, cold-conditioning process—lagering—enhances malt and hop expression while creating smooth, refined profiles characteristic of classic European styles like German bocks, Czech pilsners, and Vienna lagers.
