Michter's launched its 'US★1 Barrel Strength Sour Mash Kentucky Whiskey' for the first time, uncut and averaging 111.5 proof across its 2026 batches, showcasing the brand's award-winning Sour Mash expression. The Michter's barrel-strength release carries a suggested retail price of $120 per 750 ml and uses the signature development filtration protocol used on the brand's standard 86-proof version.
The Sour Mash product previously became the first American whiskey named 'Whisky of the Year' by The Whisky Exchange in 2019. The main tasting notes are toffee and stone fruit, with the high proof amplifying the whiskey's richness.
As collectors of American whiskey seek barrel-strength releases, Michter's shows that offering a new version of a brand's flagship product provides longtime fans with a more direct and intense experience of a whiskey they already know.
