Knucklenoggin Peanut Butter Whiskey is made locally in Wisconsin and is made from corn, rye and malted barley. The whiskey is then infused with real peanut butter and aged for 3 months in American whiskey barrels. The whiskey has a creamy and smooth taste with a hint of peanut butter that is perfect for sipping neat or mixed in a signature Knucklenoggin cocktail.
