abstract = {The veil of “Flor yeasts” are responsible for the biological aging process of wines produced in the
D.O. of Jerez and Sanlúcar de Barrameda (Finos and Manzanillas) in the province of Cádiz and Fino in the
D.O. Montilla-Moriles in the province of Córdoba, as well as in other wine-growing regions of the world, such
as France, South Africa, California, Sardinia or Hungary. The first attempts to classify these flor veil yeasts
were based on biochemical assays of sugar assimilation and fermentation. Thus, it was concluded that the
yeasts involved in biological aging belonged all to Saccharomyces cerevisiae, distinguishing four subspecies or
physiological races: beticus, cheresiensis, montuliensis and rouxii. On the other hand, molecular techniques,
which allow the characterization of oenological yeasts and discriminate between the different strains, are
usually pulsed field electrophoresis (PFGE), the analysis of the polymorphism for the length of the restriction
fragments (RFLP) of mitochondrial DNA, and multiplex PCR of microsatellites. Recent studies in our
laboratory show the existence of at least 9 different genotypes of S. cerevisiae veil of flor species, based on the
study of microsatellites (SSR-PCR). In addition, we have detected the presence of some species of nonSaccharomyces yeasts not described previously.},
