Celebrated by both the Horde and the Alliance, the Brewfest ( http://www.worldofwarcraft.com/info/events/brewfest/ ) is a time to enjoy the fermented fruits of the harvest: pretzels, cheese, and booze! The competing breweries Thunderbrew, Barleybrew, and the Ogres, all come together outside of all the major cities in a bid to outdo each other with their special ales, meads, and beers. This year's iteration of the holiday includes new achievements. Brewfest runs from September 20 to October 5.
