Lesson 05 · Barrel Proof
Barrel Proof and Cask Strength
Bourbon bottled close to the strength it came out of the barrel.
Most bourbon is cut with water down to a bottling proof. Barrel proof and cask strength bottles skip most or all of that, so you get the whiskey at full strength, often well over 110 proof.
How to drink it
Add water a few drops at a time. It is not cheating. Water can open up aromas that high alcohol hides, and you get to decide where the whiskey tastes best.
