The metabolic conversions may improve the production of a particular compound already formed by the microorganism or promote the production of a completely new biochemicals. These conversions depend on the environment. The microbiome of terroir is unique. If the term terroir is a set of physical properties of a vineyard that contribute to the specific characteristics of its wine, the microorganisms will undoubtedly form an integral part of this concept. There are yeasts, filamentous fungi and bacteria that can affect the quality of the wine. The aim of the present study was to identify the autochthonous yeast populations of grape berries collected from regions with Geographic Indications or under construction. The identification was carried out by an approach, combining Maldi-Tof-MS, PCR-RFLP of the internal transcribed spacer with 5.8S ribosomal DNA (rDNA) (ITS1-5.8S-ITS2) and sequences of the D1/D2 domain of the 26S rRNA gene. Some species are common to different GIs and in some of them other species are completely absent, besides some places are contiguous areas. In some areas, Hanseniaspora opuntiae, Saccharomyces cerevisiae, Pichia myanmarensis and Hanseniaspora uvarum were the predominant species.  aHanseniaspora opuntiae  aHanseniaspora uvarum  aYeasts  aSaccharomyces Cerevisiae  aVinho  aAutochthonous yeast  aBagas de uva  aIndicação geográfica (IG)  aPichia Myanmarensis  aPopulações de leveduras  aTerroir  aVinha1 aAGUSTINI, B.
