Those into trying experimental bourbons surely have heard of the Buffalo Trace Distillery’s Single Oak Project offerings, which started back in 1999 to focus upon how different aspects of individually selected American oak trees interact with different whiskies. I’ve put the whole back story below for those not familiar with the tale so I can focus instead upon the most recent release, the 12th go around which this time looks at tree cut, with difference in using oak from the top and bottom of the tree to age bourbon. Wood grain size and recipe also vary.Master Distiller Harlen Wheatley, in a statement from the distillery, had this to say on the topic of if tree cut matters. “From top to bottom, the tree chemistry is quite different. The chemicals most affected by the tree structure are oak lignins and tannins. Oak lignins are composed of two building blocks, vanillin and syringaldehyde. Generally there is a higher composition of oak lignins in the bottom part of the tree which in turn delivers more vanilla. Tannins are generally higher in concentration in the top section of the tree versus the bottom; however, they also vary from inside out. The outer heartwood is generally higher in tannin concentration.”
What The Single Oak Project Is
To further the variety of experiments, the barrels were filled at two different proofs, 105 and 125 proof. Two completely different warehouses were used to store the barrels, one with wooden floors and one with concrete floors. In total, seven different variables were employed in the experiment.
For eight years the tracking process continued, creating intricate databases and coming up with a potential of 1,396 tasting combinations from these 192 barrels.

Releases And Pricing
The Single Oak Project Bourbons are being released in a series every three months from 2011 through 2015 until all of the 192 barrels have been released. The first release hit select stores in 2011. This twelfth release will reach stores towards the end of February. Like all the other releases, the quantities are very limited. Every case will contain 12 bottles, each from a different barrel. The twelfth release is made up of barrel numbers 15, 16, 47, 48, 79, 80, 111, 112, 143, 144, 175, and 176. All releases will be packaged in a 375 ml bottle and priced for around $46 a bottle.
Once it is all said and done, Buffalo Trace will take the top rated bourbon from the project and make more like it under the Single Oak name.
