BUFFALO TRACE SINGLE OAK PROJECT BOURBON - The fifth round of experiments in this ongoing project will focus on three variables, the recipe, rye vs. wheat; the entry proof, 1O5 vs. 125 proof; and wood grain size, tight, average, or coarse. All of the other variables such as barrel stave seasoning, aging warehouse, char level, and tree cut (top or bottom) remain constant. As with the other four releases, people can continue to rate each whiskey they taste online at singleoakproject.com. To date, nearly 155O reviews have been given on the four various releases. Every case will contain 12 bottles, each from a different barrel. The fifth release is made up of barrel numbers 1, 17, 33, 49, 65, 81, 97, 113, 129, 145, 161, 177. Quantities are very limited. Suggested retail is $46.35 for a 375ml bottle. Available from Horizon Beverage Company.
