Michter’s Finally Takes Its Sour Mash To Barrel Strength

This May, Michter’s Distillery is releasing US*1 Barrel Strength Sour Mash Kentucky Whiskey for the first time.

“When Michter’s was being produced in the 1970’s and the 1980’s, the then-Pennsylvania distillery’s most popular whiskey was its Sour Mash,” said Michter’s President Joseph J. Magliocco. “The Michter’s US*1 Sour Mash that we make in Kentucky these days is a wonderful whiskey, and we’re excited to have this opportunity to share it at barrel strength.”

Although the whiskey is indeed made with the sour mash production process, it is so named because it draws its inspiration from a classic product made by the old Michter’s brand made by Bomberger’s Distillery in southeastern Pennsylvania. Like that whiskey, US*1 Sour Mash does not have a majority, lead grain in its mash bill in the way that bourbon (corn), malt, rye or wheat whiskeys do.

Michter’s US*1 Barrel Strength Sour Mash has a suggested retail price of $120 per 750ml bottle in the United States. The average proof of the batches being offered in this 2026 release is 111.5 proof (55.75% ABV).
