Brewfest is a popular holiday event that occurs in the World of Warcraft every year at the end of September/beginning of October. It is a celebration of the fruits of the harvest, including various beers and fattening-sounding foods like pretzels and sausage. The main areas for the event are set up just outside the cities of Orgrimmar and Ironforge, though smaller beer gardens exist outside the other major cities and inside Shattrath, as well.
There are eleven World of Warcraft achievements for players to earn, ranging from consuming copious amounts of alcoholic beverages and brewfest foods to taking the time to down the infamous Coren Direbrew or drunkenly defending the festival from a dark iron dwarf attack. There is also one meta-achievement, "Brewmaster," associated with the holiday.
There are four achievements associated with gorging oneself during the festival. The first, "The Brewfest Diet," is awarded to players who consume each of the following 8 brewfest foods: Dried Sausage, Pickled Sausage, Savory Sausage, Spiced Onion Cheese, Spicy Smoked Sausage, Succulent Sausage, The Essential Brewfest Pretzel, and The Golden Link.
There are two separate faction-specific versions of the "Strange Brew" achievement. Alliance players must consume Barleybrew Clear, Barleybrew Dark, Barleybrew Light, Gordok Grog, Mudder's Milk, Ogre Mead, Thunder 45, Thunderbrew Ale, and Thunderbrew Stout. Horde players must drink Brewdoo Magic, Gordok Grog, Jungle River Water, Long Stride Brew, Mudder's Milk, Ogre Mead, Path of Brew, Small Step Brew, and Stout Shrunken Head.
The last consumption achievement, "Brew of the Year," is awarded for consuming each of the twelve beers available through the Brew of the Month Club over the course of a year. They are: Wild Winter Pilsner, Stranglethorn Brew, Springtime Stout, Metok's Bubble Bock, Lord of Frost's Private Label, Izzard's Ever Flavor, Draenic Pale Ale, Blackrock Lager, Binary Brew, Bartlett's Bitter Brew, Autumnal Acorn Ale, and Aromatic Honey Brew.
