A Singular Idea

Mark Gillespie explores Buffalo Trace's single oak project
By Mark Gillespie
Most distilleries have a few dozen or so “experimental barrels” stashed away in their warehouses. Buffalo Trace has more than 1,500, but the idea for the Single Oak Project, the Kentucky distiller’s most extensive experiment, didn’t come from master distiller Harlen Wheatley or even the Buffalo Trace marketing team.“We were sitting in a meeting talking about aging, and Ronnie started to talk about the importance of the tree and picking different trees,” said Buffalo Trace CEO Mark Brown of longtime warehouse manager Ronnie Eddins.“It became very clear to us that he really knew exactly what he was talking about in terms of where the tree is grown, how high up on the slope, the moisture level of the ground around the tree, the growth rings per inch of the tree, the fact there is a difference in a barrel made from the top half of the tree versus the bottom half.” That was back in 1999, and Ronnie Eddins was dispatched to the forests of the Missouri Ozarks to pick a set of trees to test those differences. He selected 96 different trees based on their growth rings and the resulting grain, and the trees were sent to a sawmill for processing.Unlike most barrels in the industry, which are produced from randomly selected staves, these trees were cut in half, and each half was used to produce the heads and staves for a single barrel.The idea: to test seven different variables for their influence on the final flavour of the matured Bourbon.After eight years of aging, the 192 barrels were emptied within a week and immediately bottled to minimise any additional differences. So far, only a handful of distillery employees have tasted the 192 different Bourbons, which are being released in quarterly batches of 12 casks each until 2015.A case contains one bottle from each of the 12 casks in the release, and with most retailers receiving as little as one case of each release; it will be difficult for any one individual to acquire the entire collection.For those who do acquire a bottle of Single Oak Project Bourbon, Buffalo Trace is offering perhaps the most detailed provenance of a whiskey’s history ever.After registering a bottle at www.singleoakproject.com and adding one’s own tasting notes, the distillery will reveal all of the specifics for that particular bottle’s recipe, barrel char level, tree location, entry proof, and finally its warehouse location.Sadly, Ronnie Eddins didn’t live long enough to see the results of his test. He died in late 2010 after a battle with cancer, about six months before the initial release of the Single Oak Project. At the debut, distillery employees planted a tree at Buffalo Trace in his honour.Fittingly, it was a Quercus Alba, an American White Oak. TASTING NOTES(all bottled at 45% ABV) RELEASE #1: MAY 2011
The whiskies in this release varied only in recipe, tree location, and grain size. All other variables remained the same, and pairs of whiskies often differed by just one variable. The three variables were enough to produce subtle, yet distinctly different results. However, to preserve the unique nature of the project, I will not disclose here which whiskies had which variables.BARREL #3 Nose: Baked red apples with brown sugar, nutty with a touch of dark chocolate.Taste: Peppery with cinnamon, slightly tart apples underneath.Finish: Long, slow to fade with a touch of mint.Score: 7.0 BARREL #4 Nose: Very muted, subtle aroma of break baking, hint of hazelnut.Taste: Slower to reach a peppery peak, muted cinnamon, brown sugar, but no sign of tartness.Finish: Lingers nicely with a slight spiciness.Score: 7.2 BARREL #35 Nose: Soft honey, molasses, chocolate.Taste: Caramel cola at first, with a quickly-rising blast of black pepper that fades slowly to reveal vanilla and a slight nuttiness.Finish: Long and smooth.
