When it comes to American Whiskey, these are the top of the heap for me, but this thread is making me want to expand my collection...
Have not tried the Whistle Pig, but it has been on my list.
Willet is great bourbon, I like that one quite a bit. Willet also makes an excellent rye that I can't recommend enough. I'm hit or miss with rye - some are great and some are meh. The Willet is in a league of its own, and is the gold standard for rye as far as I am concerned. If you see it, grab it! Usually $40-50 range. And it's a little hot alcohol-wise, but it doesn't drink like it is.
(I'm trying to post a pic of my bottle, but it isn't working. Will keep trying)
