Wine Yeast

Wine yeast refers to microorganisms, most commonly of the species Saccharomyces cerevisiae or related strains, that occur naturally on grape skins and are essential for wine production. Their primary role is to convert the sugars in grape juice into alcohol and carbon dioxide through alcoholic fermentation. In the kitchen, wine yeast is used not only in winemaking but also in the preparation of homemade fruit wines, meads, and other fermented beverages. Dried strains are available in specialised shops, and different strains significantly influence the final taste, aroma, and alcohol content of the drink.
