Our predecessor, Berkeley Yeast Laboratory, opened in 1933 as both a commercial laboratory for the execution of analytical requests, and also a research facility to address the specific issues that greatly affect our regional industry.   Julius Fessler, the lab founder, was awarded the ASEV Merit Award in 1958 for such contributions, and our company remains the only industry supplier to ever receive such an award. Continuing the tradition of both service and regionally-specific innovation has been central to our laboratory’s mission ever since. Currently, much of our daily work addresses the enological hurdles and challenges that impact the North American wine industry today.  This focus is shared with a continuing emphasis upon our analytical service offerings. Many of our analyses address specific troubleshooting or decision-making scenarios such as stuck fermentation, stability analysis and beyond.
