A wholly different beast from the 10 year old and one of the rarest and most exclusive single-barrel bourbons ever produced, Michter's 20 Year Old Single Barrel Bourbon Whiskey has a seriously big flavor profile. The flagship limited edition release from Michter's Distillery, bottled at 114.2 proof is limited to fewer than 1,000 bottles worldwide. An impressive and expertly crafted bourbon whiskey, the palate offers a punchy high-proof experience, with a luxurious balance of oak and spice, followed by a finish that swims with smooth cinnamon and caramel.
