Members of the family Lactobacillaeceae were the most abundant in grape (60%), must (46%) and wine (51%). Lactobacillus, Lactococcus, Leuconostoc, Pediococcus and Weissella genera and 27 species of LAB were isolated from the examined samples. Leuconostoc mesenteroides spp. mesenteroides was the most abundant species in grape, must and wine.
