People always have ideal glass type:beer type pairings. Obviously the consensus on Belgians is that they go in tulip glasses, a German style lager would generally go in some kind of slender Pilsner glass, so on and so forth. I never hear much discussion about using the wrong glass though. Are there any glass/beer type pairings that are regarded as actually being inappropriate together? As if putting a Barleywine in a big Wheat glass could skew your experience with the style (just a hypothetical example)? In the case of IPAs, there's not really one specific glass they're supposed to go in. Tall, skinny Pilsner glasses have become one of my favorites for American IPAs, even though very few would regard them as appropriate together.
