3. Oktoberfest, Munich
This list wouldn't be complete without acknowledging the granddaddy of all beer festivals - Oktoberfest. Festivities traditionally take place from late September to the first weekend of October and entry is free. The 16-day event has attracted millions of visitors from all over the world since it began in 1810.
4. The Great British Beer Festival
Held in London every August, this is the largest beer festival in the United Kingdom. The festival focuses on real ales served straight from the cask, but also serves bottled beers and ciders. It's best to arrive thirsty - with more than 900 drinks to try, there's bound to be something for every taste. Pub snacks and traditional games are also on offer to break up the drinking.
5. Christmas Beer Festival Essen
Belgium is known for its beer and the village of Essen has put itself on the festival map with this annual Christmas celebration. Held in winter, it breaks the standard beer festival mold and offers a wide range of Belgian Christmas and winter beers. The festival offers around 200 brews to sample, including a selection of special wood-matured beers. It's grown over the years from a small local affair, to an international event that attracts visitors from all over the world.
6. Pyongyang Taedonggang Beer Festival, North Korea
It might seem like a strange location for a beer festival, but North Korea's inaugural event was launched last week. The festival aims to showcase local brews and to promote its government-owned Taedonggang Beer Factory. Taedonggang beer has been described by the New York Times as "full-bodied lager a little on the sweet side, with a slightly bitter aftertaste" and "one of the highest-quality beers on the [Korean] peninsula for several years". While it's not an easy country to visit, Koryo Tours brought 100 visitors to the festival this year.
