According to the bottle's label, Johnny Drum served as a drummer boy in the year 1861 during the Confederate (Civil) War. At the end of the war, legend has it Johnny returned home to his native Kentucky, where he staked claim among a beautiful spring. Johnny learned the importance of finding a way to convert his excess corn crop into a profitable item, rather than allowing it to go to waste. As the story goes, it wasn't long before Johnny's determination produced an exceptional bourbon whiskey. Today, Johnny Drum is bottled in three forms (though only two are reflected on Willett's website as of this writing) - Johnny Drum Private Stock, Johnny Drum Black Label, and Johnny Drum Green Label (not reflected). Owned by Willett, but bottled under the Johnny Drum Distilling Company name, it is a sourced bourbon of undisclosed origin.

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.
