Old Forester Single Barrel is crafted using the time-honoured methods established by George Garvin Brown more than 150 years ago. Old Forester Single Barrel customers will have the opportunity to sample three 100 proof barrels or three-barrel strength barrels of rich, robust Old Forester at the distillery or through an in-market selection. Barrels that produce 100 proof bourbon will yield approximately 200 bottles and, depending on proof, barrel strength selections will produce approximately 160 bottles.
