The Lab

Baker Wine & Grape Analysis started in January of 2002 and grew rapidly into a well-equipped laboratory offering a range of analytical services for the wine industry in California's Central Coast. 

Baker Wine & Grape Analysis OfficeOver time, the lab expanded its services beyond grapes and wine. BWGA earned approval from The California Olive Oil Council to provide chemical certification for extra virgin olive oil.  Microbial services such as bottle sterility, microbial cultures, yeast count & viability and DNA analysis have been added to the lineup. Distilled spirits, kombucha, cider and beer analysis services were also added as those local industries began to thrive.

The laboratory moved to its current location near downtown Paso Robles in 2015.  Our team loves providing great service and accurate results for the industries we serve, and we always look forward to working with you!

In 2006 Heather began working at Baker Wine & Grape Analysis to help with accounts and upgrade the technological processes. With a Master’s Degree in Therapeutic Recreation from Indiana University, her expertise was not initially in the science field but Heather quickly became an integral part of the lab. After 15 years of working in all areas at BWGA, Heather purchased the lab from Dr. Brenda Baker. She is excited to continue operating Baker Wine & Grape Analysis as an asset to the wine, cider, olive oil, beer and spirits industries.
