Buffalo Trace Distillery has announced the release of the last set of Single Oak Project Bourbon bottles, as the four year research project into finding the “Holy Grail” of bourbon comes to a close.

The project consisted of bottles from 192 barrels released every three months in increments of twelve 375ml bottles over the past four years. Seven different variables were studied over the course of the study: recipe (wheat or rye) - entry proof (105 proof or 125 proof) - stave seasoning (six months or 12 months) - grain size (tight, average, or coarse grains) - warehouse (concrete floor or wooden rick floor) - char number (number three or number four char) and tree cut (top or bottom half of the tree).

available from the end of February

This final of the 16 releases offers a variety of all of the above variables, which should prove to be a treat for those following along over the years, or even those who’ve just begun to taste and rate these unique bourbons.

Commenting on the set of Single Oak Project Bourbon bottles, Kris Comstock, Bourbon Marketing Director at Buffalo Trace, said: “This last release has quite the variety of bourbons. We’ve got some wheat and rye recipe, both the 105 and 125 entry proofs, all three grain sizes represented both types of warehouse floors, and oak from both the top and the bottom of the tree. The only consistencies in this release are the stave seasoning at six months and the number four char. The diversity provides a good starting point for those who aim to learn how these different nuances affect the taste, or for those current participants who want to taste test what they have learned so far.”

Kris Comstock was referring to where participants can join and review Single Oak Bourbons they have tasted. After each review, members are availed the provenance of the bourbon in which they just appraised. This allows tasters to gain insights into how each variable imparts different taste characteristics and determine which type of bourbon they prefer.

So far, more than 4,600 reviews have been given and barrel #82 remains the overall favourite, with barrels #109 and #111 not far behind.

The winning bourbon will be announced this summer, to give plenty of time for bottles of this last release to be reviewed. If the results are too close to call, a panel of bourbon industry experts will help evaluate the finalists. After the winning bourbon is announced, Buffalo Trace plans to replicate the winning bourbon under the Single Oak Bourbon name.

The Single Oak Project is part of an intensive research project Buffalo Trace Distillery started conducting in 1999 by hand picking 96 trees with different wood grains and then dividing them into a top and bottom piece, yielding 192 unique sections.

For eight years the Distillery continued with its tracking process, creating intricate databases and coming up with a potential of 1,396 tasting combinations from these 192 barrels

The sixteenth and final round of Single Oak Project Bourbon bottles will be available in the US from the end of February, with each bottle retailing for $46.35
