Bourbon insiders have long acknowledged that full proof bourbon has a distinguished and rich flavor. This bourbon underwent a distinct filtering process,forgoing the typical chill filtration and passing only through a plate and frame filter. This allowed the bourbon to maintain a robust proof for bottling, as well as a full, rich and bold flavor. Bottled at its original 125 barrel entry proof, just as it was years ago when the barrels were first filled, 1792 Full Proof Bourbon is exceptionally distinct.

The Volstead Act of 1920 which initiated Prohibition in the USA granted permits to six distillers in Kentucky to continue to bottle bourbon for medicinal purposes. Through one of these permits, Old Forester continued to be produced as medicinal whiskey on Louisville's famed Whiskey Row. It is the only bourbon continuously sold by the same company that has been available for sale before, during and after Prohibition. During this time, all whiskies had to be bottled at 100 Proof. With a barrel entry proof of 100, the “angel's share” would have created a 115 proof whiskey after maturation. To pay homage to this era, Old Forester presents 1920 Prohibition Style Bourbon at 115 proof to represent the rich flavor profile this bourbon had nearly 100 years ago.
