Because not all yeast strains are relevant for the specific conditions and characteristics of wine, a number of criteria have been proposed for the selection of new yeast strains for use in the winemaking process. One of the most important criterions for high-quality wine production is use of S. cerevisiae strain with suitable technological properties. Thus, in order to investigate phenotypic differences among 45 indigenous S. cerevisiae strains, which were identified by molecular method as different strains (see above), we screened them for the selected technological properties. The strain S. cerevisiae BS6, which is commercially available, was used as a control strain. The complete list of results, summarizing oenological properties that are important for strain selection and their application in the winemaking process, is provided in Table 2. The use of local, autochthonous, selected strains of S. cerevisiae as starters is rather preferable, since these yeasts are better acclimated to particular conditions characteristics for the specific region/area of wine production 8 and, moreover, utilization of the local isolate of S. cerevisiae is likely to raise the regional character of the wine.
