Traditional German Beer Glass
Traditional beers, with stone (rare potatoes), tin, porcelain, silver, glass or wood, their tops are usually open, or with a tin cover that can be opened with a thumb. Traditional beers are mostly half a liter or a liter of capacity, decorated with nostalgic themes, usually in Germany or Bavaria's ancient allusions. Some people think that the lid originated in the black epidemic period, in order to prevent the fly fell into the beer.
