For the first time ever, Midnight Shutdown! Shutdown Single Barrel Bourbon is a blend of four different Michigan grains with a mash bill of 58 percent corn, 23 percent rye, 10 percent malted barley and 9 percent wheat. This big, bold bourbon has a robust nose with the classic notes of caramel, leather, toasted oak and a hint of blackberry. When aged in Midnight Summer Rum oak barrels, this overproof bourbon features toasted coconut and plantain on the nose followed by notes of clove, roasted marshmallow and toasted oak and finishes with pink peppercorn rye spice over hints of papaya and vanilla.
