Buffalo Trace Distillery has engaged in an unconventional way to use infrared light waves for its latest bourbon experiment, applying the light waves to barrels before charring, with the goal of learning how new and different flavors can be drawn from the oak.
Working with barrel cooper Independent Stave Company in 2009, eight special barrels were constructed. All eight first underwent the same process as standard Buffalo Trace barrels, staves were open air seasoned for six months before being made into barrels.
Then, the barrels were divided into two groups and subjected to two different levels of infrared light waves. The first group of four barrels underwent 15 minutes of both short wave and medium wave frequency at 70% power. The second group of four barrels was subjected to 30 minutes of both short wave and medium wave frequency at 60% power. The barrels were then given a quick #1 (or 15 seconds) char, before finally being filled with Buffalo Trace’s Bourbon Mash #1.
After six and a half years of aging, the bourbon from both barrels expressed distinct flavor notes of wood, caramel, and vanilla, as well as pepper flavors drawn from the oak. Another observation from the experiment was the short wave infrared light seemed to affect more of the inner layers of the wood, while the medium wave infrared light affected the surface and medium layers.
Tasting notes for each describe the 15 minute infrared light barrels as having a floral nose followed by a complex flavor profile. Oak and tannins mingle with dry raisins and sweet caramel. The 30 minute infrared light barrels are described as strong wood notes complemented by a taste of dried fruit. A lingering finish leaves a hint of cracked black pepper.
These barrels are part of more than 5,000 experimental barrels of whiskey aging in the warehouses of Buffalo Trace Distillery. Each of them has unique characteristics that differentiate them in distinct ways. Some examples of experiments include unique mash bills, types of wood, and different barrel toasts. In order to further increase the scope, flexibility, and range of the experimental program, an entire micro distillery, named The Colonel E.H. Taylor, Jr. “OFC” Micro Distillery, complete with cookers, fermenting tanks, and a state-of-the-art micro still has been constructed within Buffalo Trace Distillery. Buffalo Trace has increased its commitment to experimentation with the recent addition of its Warehouse X. Although small in size, Warehouse X is designed to explore the extent of environmental influences on the flavor profiles of whiskey.
The Experimental Collection is packaged in 375ml bottles, with six bottles from each infrared light experiment in a case. Both entry proofs were bottled at 90 proof. Each label includes all the pertinent information unique to that barrel of whiskey. These whiskeys retail for approximately $46.35 each and will be available in late May, 2016. Experimental Collection releases are generally quite small and have limited availability.
