Cask Strength Bourbon

Cask strength bourbon is a bourbon that has been bottled straight from the barrel without being watered down. This results in a bourbon that is higher in alcohol content than regular bourbon. 

Cask strength bourbon is typically around 60-70% alcohol by volume (ABV), although some brands may be higher or lower. While cask strength bourbon may be too strong for some people to drink neat, it can be diluted with water to create a more manageable drink. 

For bourbon lovers, cask strength bourbon provides a unique opportunity to taste the spirit in its purest form. Cask strength bourbon can also be used in cocktails when diluted, providing an extra-boozy twist on classic drinks.

A Little History

Cask strength bourbon was first produced in the early 19th century when distillers began bottling their whiskeys at higher Proof levels to make them more shelf-stable and less likely to spoil during transport. 

Today, cask strength bourbon is produced by many different distilleries, and it has become a popular choice for whiskey lovers who appreciate its bold flavor and high alcohol content. While cask strength bourbon is not for everyone, it remains an important part of American whiskey history.

Are There Different Types?

Dishes such as grilled steak, BBQ pork, and dark chocolate are all good choices. The key is to find flavors that can stand up to the strength of the bourbon. By keeping this in mind, you can ensure that your next meal is perfectly paired with a cask-strength bourbon.
