Unlike Bourbon or Rye, which, by definition, must be aged in new oak barrels, Michter's US1 Unblended American Whiskey is aged in a way that utilizes whiskey-soaked barrels to achieve a rich and unique flavor profile. In late 2013, then Master Distiller Willie Pratt agreed to re-release Michter's US1 Unblended American Whiskey after a nearly three year absence from the market, deeming it "just right" and "the best it's ever been". Crucially, the US1 Unblended American Whiskey never contains grain neutral spirits - hence its unblended distinction.. PRODUCTION Small batch. Limited quantities. STATE OF DISTILLATION Kentucky BOTTLING STRENGTH 83.4 proof - 41.7% ABV COOPERAGE Whiskey-soaked American white oak barrels TASTING NOTES Deep butterscotch and vanilla notes, hints of caramel and dried fruit with a ripened fruit finish
