The nose has lots of sugar cane with a bit of a raw alcohol note. It smells much more like a white rum (rhum agricole in particular) than any sort of Bourbon. On the palate, the first thing that hits me is the syrupy mouthfeel and a surprisingly sweet flavor. Only at the end of the palate and on into the finish is there anything resembling whiskey. On that finish, I can feel the Bourbon and even a hint of rye spice.
The presence of rye is what separates the Buffalo Trace white dog from corn whiskey, which must be a whopping 80% corn and generally, doesn't include rye. In addition, the Buffalo Trace White Dog is cask strength, while most corn whiskey on the market hovers around 40% alcohol. Compared to corn whiskeys I've had, I definitely prefer the Buffalo Trace. The rye gives it a more complex flavor and the higher strength accentuates the flavor. Regular strength corn whiskey tastes pretty watered down and one dimensional in comparison.
It's interesting stuff and certainly something every Bourbon fan should try. It's hard to rate because while I think it's intriguing, and I definitely enjoy it, I probably wouldn't just relax and sip the stuff, unless I was in a "moonshine" type of mood. Still, it's well done enough to merit some serious tasting, so I give it a B/B+.
