BRETTANOMYCES SELECTIVE BROTH is a medium used for the enrichment of Brettanomyces of wines. Brettanomyces is a genus of yeast capable of growing in high concentrations of alcohol and of fermenting sugars that have not been used by Saccharomyces cerevisiae during fermentation. The presence of Brettanomyces is associated with the appearance of strange wine aromas. Brettanomyces is also called Dekkera (name given to species with sexual reproduction and therefore formation of spores by meiosis). Brettanomyces is generally found in red wines in barrels or bulk storage, since acids necessary to form some of the indicative aromas are extracted from grape skins. Brettanomyces contaminations have also been found in Chardonnay and Sauvignon Blanc. Dextrose is the fermentable carbohydrate providing carbon and energy. Peptone and malt extract provide nitrogen, vitamins, minerals and amino acids essential for growth. Yeast extract is source of vitamins, particularly the B-group. Thiamine is a growth factor. Selective agents are added to improve Brettanomyces recovery through the inhibition of common contaminants as Saccharomyces cerevisiae.
