At wine tastings doubts arise sometimes about the presence of volatil phenols, which are often the cause for barnyard, cloves, animal or stable odors. These odors are produced by Brettanomyces yeasts. Classic analysis methods include the counting of yeast cells after growth on agar medium. This analysis is not sufficient because Brettanomyces yeast may lose its ability to multiply all cells in response to stress but still remain viable. This viable but not cultivable (VNC) state is reversible. Tests were carried out in a red wine to find out if Brettanomyces yeasts, in the above mentioned state or exiting of it, retained their ability to produce volatile phenols. A stress factor of 30 mg/l free SO2 induced a VNC state. Brettanomyces yeasts ...
