Angel's Share - The Mysterious Evaporation from Whiskey Barrels

Whisky is more than just a spirit, it is a product of time, patience and tradition. One of the most poetic and enigmatic aspects of whisky production is the concept of the "Angel's Share". But what is this mysterious share and why does it play such an important role in the creation of the world's finest spirits?

What is Angel's Share?

Angel's Share refers to the amount of whisky that evaporates from the casks as the whisky ages. This occurs when the whisky interacts with the wood the cask is made of and then evaporates through the pores of the wood into the environment. Over time, this loss can be significant, especially in regions with warm climates.

Why is it important?

1. Flavor development:
   As the whiskey evaporates, it also allows unwanted components to evaporate, resulting in a cleaner, more balanced flavor.

2. Concentration:
   Evaporation can increase the concentration of certain flavors in the whiskey, creating a deeper and more intense flavor profile.

3. Economic Impact:
   Distilleries must take Angel's Share into account in their financial forecasts as it reduces overall production output.

Angel's Share around the world

The rate of evaporation varies based on geographical and climatic conditions. In humid climates, such as Scotland, Angel's Share may consist primarily of alcohol, leading to a decrease in the alcohol percentage over time. In drier climates, such as parts of the United States, water may evaporate faster than alcohol, resulting in an increase in the alcohol percentage.

Conclusion

Angel's Share is not just a loss to the distillers; it is a natural part of the whisky aging process, contributing to the final taste and character of each bottle. This poetic phenomenon reminds us that good things take time and that nature plays a central role in the creation of our favorite spirits.
