The observed responses to polyphenols could be a mechanism useful for the adaptation for growth in the particular grape/must conditions.This phenotype could have implications in the winemaking sector for maintenance of dispersed cells during the fermentation and thus opti-mal production of desired metabolites. Additionally, this communitycould contribute to an undesirable persistence of a particular strain of yeasts. For example, forming stable adhesive and invasive communities may increase the ability of yeasts to colonize grapes, processing equip-ment and within the winery. Winemakers may not have the choice of selected yeast strain they desire if the dominant yeast strain is not displaced by inoculation of a new strain. Alternatively, this mechanism may provide an explanation of microbial terroir where the microbial populations are stable and peculiar to avineyard and winery ecosystem
