Russell’s Reserve Kentucky Straight Bourbon Whiskey Barrel Proof 13 year is a premium bourbon whiskey that is aged for 13 years in charred oak barrels. It is bottled at barrel proof, meaning that it is bottled at the same strength as it was when it was put into the barrel. This whiskey has a deep amber color and a complex flavor profile with notes of oak, caramel, vanilla, and spice. It is smooth and full-bodied, with a long, lingering finish. This whiskey is best enjoyed neat or on the rocks.
