Phenols
Phenols are natural compounds that give whiskey and other spirits their distinctive smoky, medicinal, or spicy flavors. In the distillery industry, they come mainly from the peat smoke used to dry malted barley, or from the wooden barrels used for aging. Think of them as natural flavor molecules that help create the unique taste profile of spirits. When someone in the spirits industry talks about phenols or phenolic compounds, they're usually referring to these flavor-giving elements that are measured in PPM (parts per million) to determine how "smoky" or "peated" a whiskey will be.
