Sorry to post again but as I go through the cellar and find "lost" bottles I can't resist opening and trying. Just opened a Racer 5 that is close to two years old - ugh! Don't. (And, Racer 5 is one of my "go to" beers and, IMO, one of the best beers on the planet! Old is not good however). Just opened at same time a Sculpin that is also about two years old. It did not have the same character that we all expect in Sculpin. However, it was very good and quite drinkable! I probably would not age Sculpin on purpose; but, if you want to just experiment and see what happens - it ain't bad!
