The Single Oak Project is its most inventive and comprehensive experiment yet. 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 section. Prior to construction, the stave seasoning was varied. 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. This experiment allows whiskey connoisseurs to directly compare the impact of seven different 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. The Single Oak Project is undoubtedly the most extensive bourbon experiment ever undertaken.
