The only micro I've been impressed with is the Leopold Bros. American Small Batch Whiskey. It doesn't try to be a highly-aged product, but it's great for what it is. I'd like to try the McKenzie Rye, as well as other things Tom makes when they get older.
I bought some of the McKenzie Rye today. I really like it. It's only aged a year, but they use smaller casks and then finish it in sherry casks. It doesn't taste young at all. It reminds me of Scotch.
