"Prior to opening Bierstadt, we had been BSI customers for over 20 years. Bierstadt has never used any other yeast supplier, and wouldn't. We have traveled to Europe with the owners and watched the brewers at several German lager breweries harvest yeast for them to bring back. In our opinion, BSI is largely responsible for the resurgence of lager in America and instrumental in improving the quality of beer in our industry. You can do no better."

Founders, Bierstadt Lagerhaus

"I've been a customer for 22 years and I must say BSI has been a great help to me and a bottomless source of knowledge. They are great folks and stand behind their products. We've been blessed with 11 Gold, 6 Silver, and 6 Bronze Medals and Awards and BSI yeast was in every one of those beers."

John Dean

Brewmaster, Blind Tiger Brewery

"BSI has been an incredible partner in our success and growth. David and Bryan know yeast for sure, but they were first brewers, and they advise us based on their actual hands-on experiences, rather than with just theory. Furthermore, unlike the 90% of US craft breweries producing mostly ale, we are highly focused on German lagers. To our benefit, BSI is passionate about promoting traditional lager brewing, which they have nurtured with strong connections to the brewing culture in Germany."

Stephen R. Holle

founder, Kansas City Bier Co.

"At OCC Brewing we strive for the highest quality standards when it comes to our beer, food, and service. Having worked at BSI for several years prior to opening our brewery, I can attest that they also strive for the highest quality standards in the industry. "It's All About the Fermentation" when it comes to our beer and I wouldn't trust our beer to anyone else's yeast! Cheers to David, Bryan, Cori and the entire BSI family!"

Dan Ramos

founder, OCC Brewing

“What I love about BSI is the consistency of their yeast. Know that I will get consistent and great fermentations every time.”

Steve Parker

founder, Fidens Brewing

“The team at The Brewing Science Institute is very helpful every step of the way. They have helped me determine which yeast strain to use for experimental beers, discussed streamlining fermentation programs and even let me use proprietary strains of yeast never before used on a production scale to gain data and flavor profiles. Quality is always top notch, delivery times are consistent and the level of knowledge the entire team holds is world class. ”
