Hirsch The Bivouac is a 100-proof Kentucky Straight Bourbon Whiskey, bottled-in-bond, that blends two different sourced bourbons from Bardstown, Kentucky. It features a primary blend of 3-year-old bourbon (74% corn, 18% rye, 8% malted barley) and a smaller amount of a higher malted barley, 6-year-old bourbon (72% corn, 13% rye, 15% malted barley) for added complexity. The whiskey offers a balance of sweet and spicy notes, with flavor profiles often described as having hints of vanilla, caramel, oak, cinnamon, nuts, and dark chocolate.
