Cologne, Germany

Cologne is home to Kolsch — a crisp, delicate top-fermented ale that by law can only be brewed within the city and its immediate surroundings. Over 20 traditional Kolsch breweries operate in Cologne, most with their own brewpub (Brauhaus), where cylindrical 200ml glasses called Stangen are kept coming by waiters known as Kobes. The Fruhlingsfest each April kicks off the city's beer calendar in style.
