I collect craft brew bottles, but I only keep bottles that I've sampled and reviewed myself. At four hundred plus bottles, I have a need to branch out to some high quality regionals such as Russian Rivers and Three Floyds. Trading seems to be the best option. I have access to many good brews. Terrapin, Cigar City, Dogfish Head, many trappists, lambics, Bell's, not to mention the awesome local brewers: Intuition, Bold City, Greenroom, and Engine 15.
