Welcome to the next installment of Bourbon and BS: Episode 6; Yeast and Fermentation. This episode dives into fermentation — the biological engine that turns cooked grain mash into the alcohol‑rich foundation of every whiskey. We explore how yeast selection shapes this stage, from
common brewer’s and distiller’s strains to tightly guarded proprietary cultures kept genetically pure for generations, and even multi‑strain approaches like those used at Four Roses. Each choice influences the creation of congeners, the flavorful compounds that define a distillery’s character. By the time distillation begins, these yeast‑driven differences have already set the stage for a uniquely complex and expressive white dog.
