debeer1-5, Exercise 2: Kölsch and Altbier

Model answer:

Kölsch comes from Cologne (Köln): a pale, clean, lightly hoppy ale, served in small straight glasses. Altbier comes from Düsseldorf: a copper-brown, bitter, malty ale, the name meaning "old" after the ale-brewing method that came before lager. A city might protect the name of its beer because the style is part of its identity and its trade; protection keeps the name tied to the place and stops outside breweries borrowing the reputation, as with protected regional names in the European Union.
