The Fermentation Service Laboratory at the University of Tennessee analyzes grape juice, wine, beer, and cider samples to support the production of high-quality products across the state. Customers have access to analytical data as well as consulting through the extension mission of the university. Other samples like distilled spirits, kombucha, or formulated beverages can be analyzed upon request.
