Yeast in wine is a microscopic, single celled fungus, typically Saccharomyces cerevisiae, which triggers fermentation by transforming the sugars in must into ethanol and carbon dioxide. Yeasts are essential for converting grape juice into wine and they determine its final alcohol content, aroma and flavor profile. They can be wild yeasts, naturally present in vineyards, on grape skins and in wineries; or cultured yeasts, which are specifically grown in the lab.<\/p>\n","protected":false},"author":4,"featured_media":0,"template":"","glossary_category":[113],"class_list":["post-14114","wcp_glossary","type-wcp_glossary","status-publish","hentry"],"yoast_head":"\nWhat is Yeast?
