The ideal gift! Buy the best bourbon online. Price and reviews available for Michter’s US-1 Kentucky Straight Bourbon Whiskey – 750ml Bottle. Michters US-1 Bourbon is made from a carefully selected mashbill that features the highest quality American corn. It is then matured to the peak of perfection, with barrels often aging in excess of eight years. Truly small batch, each batch of our US*1 Bourbon is typically composed of no more than two dozen barrels, leaving no margin for blending out imperfection and thus necessitating excellence from every barrel. Reflecting the spirit of the Bluegrass State, Michters US*1 Bourbon is nuanced, mellow, and earthy.
