Released in December 2013, Michter’s Celebration Sour Mash marked a category-defining moment for ultra-premium American whiskey. The extraordinary Michter’s Celebration Sour Mash blend consists of Kentucky Straight Bourbon and Kentucky Straight Rye taken from Michter’s best barrels: some aged over 30 years, some aged over 20 years, and some other truly exceptional barrels – all hand-selected by then Master Distiller Willie Pratt.
