This single barrel Old Forester was bottled specially for Largo Beverage. The bourbon matured in Warehouse K on Floor 3, and is bottled at a barrel strength of 127.6 proof. Old Forester is the longest-running bourbon brand on the market today. It was introduced in 1870 by George Garvin Brown, one of the founders of Brown-Forman. The bourbon has now been continuously produced for over 150 years. It was even available during Prohibition, when it was sold as a medicinal whiskey.
