This expression is RD1 Spirit's first exploration to marry the craft of traditional barrel-aged bourbon with modern finishing techniques focusing on unique wood. French Oak, commonly known for its complimentary aging to cognac and wine, is considered an elite wood due to its tightness of grain and depth of flavor complexity. This oak comes from the great five forests of Central France. It is seasoned for two to three years in Northern California and then cut, milled and toasted to our specifications. Simultaneously, RD1 Kentucky Straight Bourbon was aging in new American Oak barrels. After 4+ years, we inserted French Oak wood staves into the barrel for additional aging. The French Oak beautifully rounds out flavors and develops a mellow, easy drinking bourbon.
