Good quality Single Malt Scotch does the trick for me, though, and I've come to have an open mind about them, they're all different, some very different. Compare something like Laphroaig to Talisker for example. Two completely different worlds, and I like them both.
Caol Ila has come to be my favorite. Greenish in color when it's in the glass. Add a drop or two of water..Somewhat smokey, peaty, and all that other stuff going on. i love it.
another one I really like is Oban. no peat and smoke, just a lot of flavor.
Second the Caol Ila. At a Scotch tasting a few weeks ago, sampled 6, Caol Ila was the most dentist's office, horrible stuff of the bunch.. and then it wasn't. It was clearly the best. Talisker was my second, my wife favored the Jura Superstition. Cool bottle, but tasted to me like good bourbon. I want smoke, peat, licorice, vapo-rub.... character!
