Mmm... Pappy Van Winkle's 15 Year Family Reserve.

Somewhat pricey (if you can even find it - seems to be around $60 a bottle these days anyplace that has it in stock), but absolutely worth it. Got rated 98 by Beverage Tasting Institute and top listings by many other reviewers.

Some prefer the 20 Year Reserve, others think this is the better bang for the buck; I've not had the 20 year yet and so can't compare, but the 15 Year is flat out the best I've ever had.

I like Booker's too, and Knob Creek is pretty good for a few more steps down the rungs...

Merry Christmas!
