Yeast is a fundamental ingredient in shaping the flavor of bourbon and rye whiskey. It produces esters, phenols, and aldehydes during fermentation, influencing fruity, spicy, or floral characteristics. Bourbon’s sweet and buttery profile stems from specific yeast strains, while rye whiskey’s bold character is enhanced with spicy or tropical nuances. Shankar Distillers employs proprietary yeast strains to craft unique spirits that honor tradition and innovation. With advancements in biotechnology, distillers can now explore new yeast strains, redefining whiskey flavors while maintaining their rich heritage.
