Beer glassware comprise vessels, today usually made of glass, designed or commonly used for serving and drinking beer. Styles of beer glasses vary in accord with national or regional traditions; legal or customary requirements regarding serving measures and fill lines; such practicalities as breakage avoidance in washing, stacking or storage; commercial promotion by breweries; artistic or cultural expression in folk art or as novelty items or usage in drinking games; or to complement, to enhance, or to otherwise affect a particular type of beer's temperature, appearance and aroma, as in the case of its head. Drinking vessels intended for beer are made from a variety of materials other than glass, including pottery, pewter, and wood.
In many countries, beer glasses are served placed on a paperboard beer mat, usually printed with brand advertising, in commercial settings.
