Jim Beam Signature Craft Quarter Cask is the third edition from the Jim Beam Signature Craft line and second limited-edition expression. This full-bodied Kentucky Straight Bourbon is bottled at 86 proof, starts with premium Jim Beam Bourbon aged at least five years and is finished with a variety of fine quarter cask bourbons, and all aged at least four years in smaller barrels. By building on a base of mature liquid and finishing it with quarter cask aged liquid, the inspired distillers at Jim Beam were able to craft just the right balance of rich vanillas of a mature bourbon profile and the extra oak notes of the quarter cask bourbon.
