Phenols are natural compounds that give spirits like whiskey and scotch their distinctive smoky, medicinal, or spicy flavors. Think of them as flavor building blocks that come from wood and peat used in the production process. When someone mentions phenols in spirits production, they're usually talking about how smoky or peated a whiskey is. The more phenols present, the smokier the taste. This is especially important in Scotch whisky production, where the level of phenols (often measured in PPM - parts per million) can determine the style and character of the final product.
