charcoal mellowing

Charcoal mellowing is a process used in whiskey production to smooth out the flavor by gently heating the spirit through charcoal filtering. The whiskey is passed through or stored with charcoal, which helps absorb harsh compounds and impurities, resulting in a softer, mellower taste. This technique, often associated with traditional methods like Kentucky bourbon or Japanese shochu, enhances the drink’s balance and roundness without significantly altering its essential character. Essentially, charcoal mellowing acts as a natural refinement step, making the whiskey more approachable and enjoyable for a wide range of tastes.
