The nose is full of butterscotch with a bit of maple syrup. On the palate the first taste is sweet with some very sophisticated Cognac-like notes, then spice box and some nice brine. The finish is full of spice, almost hoppy at times reminding me a little of Charbay's hopped whiskey.
This is really an amazingly flavor-packed, complex bourbon. I like the current Eagle Rare, but this version is just above and beyond it in terms of complexity.
