Milam & Greene Single Barrel Straight Bourbon Aromas of nuts and baking spices that give way to soft vanillas and chocolates. This classic bourbon has sweetness derived from the corn married with a lot of spicy character that comes from a higher rye content. The malted rye provides pepper and spiciness while retaining smoothness and characteristics that are like a wheated bourbon. It's luscious and rich, with a lingering finish.
