I tried Sam Adams' Triple Bock. It comes in a 20oz bottle. I knew when I bought it I figured that something that comes in a bottle that small I probably might want to put it in a glass smaller than a half pint. The guy at BevMo assured me I was overestimating. Well let me tell you a tulip glass would be better.
The brew is thick, like barley wine. The fragrance is chocolate, so much so I had a suspicion cocao was added to the fermenter, but the flavor is coffee, with prune in the back.
As I said earlier I would use a tulip glass to drink this beer. Just to be clear I mean a champaign glass, and don't put alot in the glass. This beer has a lot of flavor so I wouldn't reccomend quaffing this brew. I'm sure the brewer had this in mind when they made this brew. Which answers why there is a cork on top rather than a bottle cap. While the drinker enjoys the complex flavors the rest of the bottle can be put into the fridge to keep it cold.
One doesn't have to worry about the beer going flat, it already and. Carbonation would just get in the way of the thick mouth feel.
