Already one of the best distilleries on the Bourbon Trail, Buffalo Trace isn't one to rest on their laurels. The pioneering distillery is in the process of releasing the Buffalo Trace Experimental Collection ($46 each), the returns from testing recipes and barrel treatments that began two decades ago. For their most recent wheat entry, the same bourbon recipe was put into barrels at different proofs (from 125 to 90) and aged for 11 years and 7 months. All four were then bottled at 90 proof. There isn't a bad one in the bunch, so grab one for your collection or all four for a taste test experiment of your own.
