What are “finish” barrels in bourbon production?

“Finish” barrels in bourbon production refer to barrels that are used for additional flavor infusion after the initial aging process. After a bourbon has aged for the required period in the primary barrels, which are often new charred oak barrels, it can then be transferred to these finish barrels. These finishing barrels can have previously held other spirits, such as rum or wine, or been subjected to different treatments that impart unique flavors and characteristics to the bourbon.

Using finish barrels allows distillers to experiment with various flavor profiles, enriching the complexity of the bourbon. This practice is becoming increasingly popular as it provides a way to add nuanced flavor notes that distinguish a bourbon from others, enhancing the overall tasting experience. The choice of finishing barrel plays a significant role in the final product's profile, showcasing the creativity and craftsmanship involved in bourbon production.
