Michter's US*1 Barrel Strength Sour Mash is a premium Kentucky whiskey bottled at its natural barrel proof for maximum character and depth. Distilled and bottled in Kentucky, this expression from Michter's showcases the full intensity that barrel strength bottling delivers.

The whiskey opens with layers of caramel, dark toffee, and buttery vanilla, with complementary notes of toasted oak and hints of spice and smoky sweetness. Despite its bold barrel strength profile, it delivers a remarkably smooth sipping experience with a long, warming finish. It is well-regarded among whiskey collectors and enthusiasts seeking a complex and distinctive American whiskey. Costco carries this in a case of three 750ML bottles.
