Buffalo Trace Distillery CEO Mark Brown dubs this the "Holy Grail" of whiskey. This Kentucky Straight Bourbon Whiskey is aged in oak barrels made from a single tree. The Single Oak Project is the most extensive bourbon experiment ever undertaken. It all started with 96 individually selected American oak trees that differed according to the number of growth rings per inch and growing location. Each tree was then cut into two parts - top and bottom - yielding 192 unique tree sections. A single barrel was constructed from each unique section. Before construction distillery varied the stave seasoning times. The 192 barrels were then charred differently. These single oak barrels were then filled with different recipe whiskeys, at various entry proofs and aged in a variety of different warehouse styles. We believe that this experiment will allow you to directly compare the impact of 7 various critical variables across 192 bottles for a total of 1,396 taste combinations. None of the 192 bottles in the complete set are exactly alike.
