and the Cannstatter Volksfest, most German beer festivals are also funfairs. They are called "Volksfest" (festival for the people) and are numerous in Germany.

United Kingdom British beer festivals focus on draught real ale, although bottled beers and ciders are often included. There is also an emphasis on variety as well as volume. Festivals can be organised by the Campaign for Real Ale (CAMRA), pubs, brewers, social and sporting societies or charities. CAMRA festivals are run by volunteers under the direction of local branches and the admission fee is reduced or waived for CAMRA members. Pub festivals use professional bar staff and there is usually no entry fee. Larger British beer festivals are usually held in large indoor venues (Kensington Olympia in the case of the GBBF).

Staff serve beer directly from the cask and take payment in the form of cash or tokens purchased at the entrance.
