One of the key steps in creating any kind of whiskey is the aging process, where a freshly distilled spirit is put into wooden casks or barrels and left there to age for a period of years — up to 30 years or more in the case of some high-end whiskeys. As the spirit spends time pressed up next to the wood, it absorbs some of the flavors, which mellows out its taste and adds notes like vanilla and oak. The process also turns the spirit from clear to brown, giving a richness in color, too.
Traditionally, you’ll find many whiskeys aged in oak barrels. These can have previously held a different drink, so, for example, you might get a whiskey aged in a barrel that previously held sherry, or rum, or port. The wood will have picked up flavors from the spirit that it previously held, so some of these notes will be transferred to the whiskey as well. One very popular combination is using bourbon casks to age scotch whisky, adding sweet and fruity notes.

As for bourbon itself, that is traditionally aged in new oak casks, meaning ones that have never held a spirit before. In fact, it’s a legal requirement in the U.S. for bourbons to be aged in new oak. However, there is some leeway for using pre-used casks in the production of bourbon thanks to the finishing process. This involves a final step after aging, where the bourbon is placed into a cask for several months to pick up a final round of flavors.
