I guess that would be this one. I'm kind of disappointed it's only going to be 7 years old. I suppose it's essentially barrel proof Buffalo Trace, which is something I'd like to try, but not for nearly 4 times the price of regular Buffalo Trace.
Next time you're at Jack Rose, try the Willett Matinee and French Connection. The Matinee is almost certainly BT. I can't tell about the French Connection but I believe it to be.
