The invention relates to a method for selecting oenological yeasts based on at least one oenological character, characterised in that it comprises the following steps: identifying a locus associated with said oenological character of interest; identifying an allele promoting said locus; making a molecular marker capable of detecting the allele promoting said locus; screening oenological yeasts with the molecular marker in order to select the yeasts having said promoting allele and thus the oenological character of interest.
