What is the typical result of aging distilled spirits in wooden barrels?

Aging distilled spirits in wooden barrels typically leads to the development of a smoother taste and a richer flavor profile. This process occurs as the spirit interacts with the wood, which imparts various compounds. These interactions can soften some of the harsher elements of the alcohol and contribute additional flavor characteristics such as caramel, vanilla, and spices, depending on the type of wood used and the previous contents of the barrel. The exposure to oxygen during aging also plays a crucial role, allowing for oxidation reactions that enhance complexity in flavor. Essentially, the aging process transforms the raw spirit into a more nuanced and palatable beverage.
