Wine yeast

Wine yeast refers to specific strains of yeast, most commonly Saccharomyces cerevisiae, used in winemaking to ferment grape juice into alcohol. The yeast consumes the sugars in the juice and produces alcohol, carbon dioxide, and flavor compounds, which shape the wine’s taste and aroma. Different yeast strains can influence the wine’s character, aroma, and fermentation speed. Winemakers select particular yeasts based on the desired style, climate, and grape variety. In essence, wine yeast is a natural microorganism essential for transforming grape juice into the complex, alcoholic beverage we enjoy as wine.
