Jim Beam Signature Craft's Whole Rolled Oat Bourbon is part of the Harvest Bourbon Collection. This series of six unique bourbons using differing grains and aged at least eleven years shows off the experimental side of Beam, and allows bourbon enthusiasts to explore new grains and how they contribute to the overall flavor of each of these bourbons. Aged 11 years, this is a mild, light-bodied bourbon that’s easy to sip. The oats mellow the spirit, giving it an almost nutty flavor.
