Beer pairing dinners in my area seem to be on the rise as more craft beer-centric establishments show up. This may not be true across the world, but I see this practice becoming increasingly common.
BeerAdvocate, a noted resource amongst all the beer fanatics I know, has a guide to pairing and another specific guide for pairing with cheese.
Epicurious, home of magazine content from Gourmet, Bon Appetite, and others, has a guide to how to pair that relates beer to wine.
Brewers Association, a group of craft brewers and organization to advocate for craft breweries, has a guide to pairings with information from a published cookbook. Their online store has several titles that may provide interestedinteresting resources.
