Sparkling wine is one of the most expressive and technically demanding wine styles. Its character begins with the grape variety, the vineyard, and the production method, but the final sensory signature depends heavily on yeast. Yeast acts as the invisible winemaker, shaping aroma, flavor, texture, and bubble structure throughout both primary and secondary fermentations.
