I got into whisk(e)y back in college, so I started off with some pretty rough stuff. At one point I thought Jim Beam was the best stuff in the world because of how it compared to the other stuff I was drinking.
But recently, I've branched out a bit. Here's a list of the bourbons I've been drinking recently:
Maker's Mark
Wild Turkey 101
Old Granddad Bonded
Buffalo Trace (really nice stuff)
Unfortunately Scotch and Irish whisky are fairly expensive over here in the States so havent had the chance to sample many. But J&B is pretty good, Black Bush is great, as is Jamesons.
J&B with a little soda-water (ie. just carbonated water) is a nice simple drink. Not sure if you consider that blasphemy or not, heh.
