Ancient Age 90 Proof, produced by the famous Buffalo Trace Distillery, is a variation on the traditional Ancient Age, which is bottled at 80 proof. The brand was introduced by Schenley in 1946 and has been made in the same way ever since. Just like Ancient Age 80, this bourbon has been matured for 36 months. The label has a cool vintage design, referring to the original period in which the whiskey was made. Simply a cool bottle of Kentucky Straight Bourbon Whiskey!
