If you’ve ever heard a distiller lamenting how much whiskey they lose during aging, they’re probably talking about the Angel’s Share. It’s not about celestial beings getting a little tipsy on the job, but it is a crucial part of what makes aged spirits so special. This natural phenomenon plays a significant role in concentrating the flavors and character of the whiskey you enjoy.

Definition

The Angel’s Share is the portion of whiskey that evaporates from the barrel during the aging process. As spirits mature in porous oak casks, environmental conditions like temperature and humidity cause a certain amount of liquid to escape through the wood. In warmer climates, more alcohol evaporates, while in cooler, drier conditions, more water evaporates. This process means that over years of aging, a significant volume of the original spirit is lost to the atmosphere—a tribute paid to the “angels.”

Why does it matter?

This loss isn’t just a headache for accountants; it’s fundamental to creating a complex and flavorful spirit. As the liquid evaporates, the remaining whiskey becomes more concentrated. Flavors from the mash bill and the charred oak barrel become richer and more pronounced. The Angel’s Share is why an older bourbon often has a deeper, more robust profile and a higher proof than its younger counterparts. This concentration directly impacts the final taste, texture, and even the price of the bottle, as less liquid is available to be bottled from each barrel.
