I was quite surprised when I bought a 6 pack of Guinness bottles (dark, black almost 'painted' bottles) the other day that they have the message "please drink directly from the bottle" on the cap and bottleneck. They no longer use the 'widget' technology anymore, that's how long it had been since I have drank one.
What I imagined to be a very hearty dark, meal-like stout ended up being incredibly "flat" tasting. That really surprised me as the head of the beer itself usually took up a large portion of the glass if you chose to use one, but it seemed to taste awfully flat and lacking any kind of carbonation.
Has it always been that way? One good thing is that it did not bloat me after drinking the 6 pk, but again--it just didn't seem to have any kind of 'kick' as far as being carbonated anymore. Maybe it's just been too long since I had one that I don't remember.
Figured I'd ask since you brought it up.
