Whiskeys

• Most bourbons, scotches and other varieties of whiskey are either 80 or 86 proof, but several distilleries also produce whiskeys with higher alcohol content. For instance, Old Grand Dad offers a 100 proof version along with its standard 86 proof blended whiskey, and Wild Turkey has a 101 proof bourbon as well as a rye whiskey with the same alcohol content.
  
  

Vodka and Rum
