title_body: How to pair a beer with a glass?
upvoted_answer: It might sound snobbish to be peckish about the type of glass but the glass does influence the taste of the beer. 
  
  Some things are:
   - the thickness of the glass. A thin glass invites to a more delicate way of drinking, a really thick glass would let you expect a sturdier beer.
   - the surface compared to the volume of beer. A big surface gives a change to let of more aroma's but I would think you also need a little more foam.
   - the capacity to keep the aroma's. As pointed out by Rube. Think of a cognac glass versus a vase. Some glasses also take in you nose deeper than others.
   - the way the beer flows. The shape of the glass how quickly you can drink it without spilling. Think of kwak, you HAVE to drink the last very carefully.
  
  So to answer your question: there are many factors how the glass influences how you taste a beer. What's best is very subjective. You could at first stick to the opinion of the brewer, what he finds the best glass for it. If you like the taste with an other glass better, use that. I would not approach this as a hard science. Brewers might choose a specific glass to "stand out".
