This is a minimalist approach that would make a Belgian waiter's moustache lose its waxed point. Belgium is the land of the beer glass fetish. Here, the greatest concession to ceremony is usually reserved for imported weisse beers, often treated to a tall Bavarian weisse beer glass with a citrus wedge perched on the rim. The answer is yes, up to a point. Conventional ales and pilsner style beers have no special requirement other than a glass that has an appropriate size to easily take a 12-ounce pour and leave room for the head.
Life is too short to wait around for heads to settle before pouring the last dregs of the bottle.
If you value a head on your beer, make sure that there are no traces of detergent in the glass. Detergent neutralizes head formation and will prematurely flatten your beer. In the case of Belgian ales, there is no need to go to the extreme of having a different glass for each brand of beer. However, the Belgian approach is still useful when it comes to appreciation of Belgian-style beers. Belgian abbey ales and other Belgian specialty styles are meant to be constantly savored for their aromas as well as their flavors.
