I've really been into bourbon for the last year. Two weeks ago my wife and I took a vacation to the Kentucky bourbon trail, went to 9 distilleries and a cooperage. Great times, many samples and many bottles of Kentucky-only bottles brought home. I highly reccomend it!
My current collection is around 12 bottles. Evan Williams Single Barrel (2002 & 2003 editions) and Four Roses Single Barrel make up my "top shelf" right now. I plan on getting some Blanton's soon, and of course the elusive anything by Pappy Van Winkle. My more regular dram has become Very Old Barton 100 proof, love that stuff.
