Glass of Koelsch, Cologne - This unique local beer is pale and highly fermented. It comes served in relatively small glasses (for Germany) carried by waiters in large, circular bucketed serving trays. Typically, at the Peters Brauhaus pictured here, staff use a time-honored technique to keep track of the number of beers consumed per group of patrons: after each beer is served, another mark is made on the tabletop cardboard coaster. At the end of the night, the marks are tallied and the bill is paid.
