I'll just throw in my objective 2 cents worth here for the sake of defending glass styles and say without being pompous or instructive, that although the Trappist style goblets could appear as having no practical qualities other than being grandiose or pretentious, theres a few design purposes that affect factors other than taste, for those who aren't aware.
1. The stem prevents heat from the drinkers hand from being transfered into the beer. Is this necessary? No, but if you're drinking a Chimay or something it's going to be a sipping beer, not a guzzling beer at the pub, so it sure helps.
2. The wide rim of the glass apparently accents aromatic qualities. We're presuming of course the people who're drinking premium beers care for such a thing.
3. The wide rim also accommodates for enhanced carbonation in some of the more Trappist/Belgian style beers such as La Chouffe, which has unrelenting carbonation in which a pint glass wouldn't manage greatly.
I haven't missed any 'point' to this thread, I'm just stating this to justify this certain style, for anyone who thought they were 'pointless' when paired with beer. Obviously, given the context, drinking a Fat Yak out of one of these isn't utilising the intended purposes of such a glass, but hell, if you just like the aesthetics of the glass, then why not drink out of it? I don't doubt they're marketed and paired with these beers because they think the public will want to snap them up because they 'look cool'. And they do, IMO. And who cares if those people aren't aware of the appropriate style for the glass or drink their macro-beers from them. It's not as if the Glassware Police are going to burst in through your door and take you to court on charges of 'Inappropriate glassware usage", and at the end of the day, they're the ones critiquing and deconstructing blatant flavoured beers, so let them.
