QUEST FOR WINE YEASTS - AN OLD STORY REVISITED

Numerous studies have described the yeast biota of grapes, and grape m ust in order to understand better the succession of yeasts during ferm entation of wine. The origin of the wine yeasts has been rather contro versial, By using more elaborate isolation methods, classical genetic analysis and electrophoretic karyotyping of monosporic clones, with th is study, credible proof now exists that the vineyard is the primary s ource for the wine yeasts and that strains found on the grapes can be followed through the fermentation process.
