The yeast S. cerevisiae synthesizes a variety of volatile aroma compounds that form a very important part of the ‘character’ of the final wine and the task of choosing a yeast strain to produce desirable attributes in the final wine is significant. The preferable flavors of wine depend on a balance of volatile constituents such as acids, alcohols, aldehydes, ketones and esters, with yeast bouquet resulting largely from higher alcohols and esters (Swiegers et al., 2005).
