This test allows the quantitative detection of the real beer spoiling species of lactic acid bacteria. There are more than 200 Lactobacillus species described, from which only a few are proven to cause spoilage in finished beer. 

These real spoilers are the Lactobacillus species L. acetotolerans, L. backii, L. brevis, L. casei, L. collinoides, L. coryniformis, L. lindneri, L. parabuchneri (“frigidus”), L. perolens, L. plantarum, L. rossiae, and the Pediococcus species P. damnosus and P. inopinatus. 

All these species are specifically detected together in one screening test which provides a simple and easy result read-out for the presence of real beer spoilers in your sample as a “go-no go” test.
