Wine Microbiology Products

We offer easy-to-use test kits and media for wine microbiology testing. This includes tests for total aerobic counts (pre-bottle sterility), yeast and bacteria as well as tests for determining the presence of the wine spoilage yeast Brettanomyces ("Brett").

Our Brett tests include the “Easy BlueTM” kit: a complete-do it-yourself Brett Test kit. To use our Easy Kits, wine or juice is applied to a plate, pre-measured mixing beads are then applied, and the plate is shaken. After a short incubation period, there will be a color change, a strong phenolic odor (if the wine contains Brettanomyces), and the development of countable colonies that indicates the concentration of cells in the starting sample. We also offer a range of Brett tests useful for the lab, testing grapes, barrels and surfaces. 

See our wine testing products section for a complete list of our wine microbiology tests.
