Direct from the barrel whiskey is at its most authentic — the way its makers taste it day after day, year after year. No, you don't have to drink it straight. In fact, sometimes you shouldn't at all. Buying a bottle of cask strength whiskey is less about intention and more about options. In cocktails with lots of ice, it keeps its potency longer and staves off dilution. In a glass all by itself, it tastes just the way nature made it, and let's you play the master for a while. Water? Ice? A splash of soda or lemonade? We assembled the best new cask strength whiskeys, so you can try every permutation on your own.
