Found a 2012 bottle at my local store and had to pick it up. Served chilled from a 12 oz bottle and poured into a snifter. Pours a light brown and slightly purple color with a very thin head. Smells are of fruits-cherry and grape mostly, and a hint of booze, molasses and caramel. Carbonation is pretty light with a medium body. Taste is fruity and yeasty, with a bit of a funk as an aftertaste.
I'm happy that I bought it (and one other to store away) but this was nothing special. I don't know if it was stored properly. It still is surprising that my grocery store still had this on the shelves. I typically enjoy Dubbels, but not this one
EDIT: I spoke with a beer shop owner in the West Village after writing this post and was informed that Goose Island will stop producing this beer. They shipped out all of the inventory they had, including many 2012 bottles. I have seen the beer at numerous locations, so the place I initially purchased it had stored it properly. I have two more bottles in my inventory, but plan on aging them another 2-3 years.
