Customer Testimonials
"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."
