Autochthonous yeasts as one of the tools to produce wines by original technologies
Keywords:autochtonous yeast, extracellular enzymes, Hanseniaspora uvarum, non-Saccharomyces, spontaneous fermentation, wine
This review focuses on autochthonous wine yeasts that occur naturally in a specific geographical area, and their role in wine production. The distribution of individual species changes during ripening and processing of grapes and fermentation of the grape must. The composition of autochthonous microflora is influenced by many factors including interspecific interactions. Autochthonous yeast populations lend to wine flavor and taste typical for a specific geographical area. The article describes the fermentation of grape must, changes of autochthonous yeast microflora during spontaneous or combined fermentation, and includes an overview of the basic species of autochthonous yeasts.
