The Blue Run team has selected 12 different single barrels of their High Rye Bourbon, which was contract distilled at Castle & Key Distillery. Each barrel, which featured a #4 alligator char and was aged in Frankfort and Bardstown, KY, has its own unique personality based on where it was in the rickhouse and how the whiskey reacted to the wood. They range from 115-117 proof and the color of the butterflies vary based upon the distinct flavor profile.
