There is no official smoothest whiskey. Smooth is not a TTB class. Read the type — bourbon, rye, Scotch, Irish, Tennessee — and the proof on the neck. 100 proof is not bottled-in-bond. A 1.5-ounce pour at 40% is one NIAAA drink. Age statements follow
Related: good bourbon, whiskey neat, straight bourbon.
