bourbon cask

A bourbon cask is a type of wooden barrel used to age bourbon whiskey. Made primarily from oak, these barrels impart unique flavors such as vanilla, caramel, and spice to the spirit during maturation. Since bourbon must be aged in new, charred oak barrels, the cask's material and char level significantly influence the whiskey's color and taste. The aging process in bourbon casks allows the whiskey to develop complexity and smoothness over time, making it a crucial element in the production and flavor profile of bourbon bourbon.
