Boulder, CO • January 12, 2011—The Brewers Association (BA) recently released its 2011 Beer Style Guidelines. Updated annually, the guidelines currently describe 140 styles of beer and are used in prestigious beer competitions, like theGreat American Beer Festival® and theWorld Beer Cup®.

For 2011, several beer style descriptions have been significantly updated:
Belgo-American-Style Ales
Belgian-Style Flanders Oud Bruin/Oud Red
German Bock
Rye Beer
Additionally, two beer styles have been renamed. American-Style Sour Ale is now known as American-Style Brett Ale, and its description has been significantly revised. American-Style Black Ale is the new name for American-Style India Black Ale, and it too has updated style guidelines.

Since 1979 the BA has provided beer style descriptions as a reference for brewers and beer competition organizers. The beer style guidelines developed by the BA use sources from the commercial brewing industry, beer analyses, and consultations with beer industry experts and knowledgeable beer enthusiasts as resources for information. Much of the early work was based on the assistance and contributions of beer journalist Michael Jackson. For 2011, revisions were aided by over 150 comments and suggestions from Great American Beer Festival and World Beer Cup judges, as well as other beer industry members.

“These guidelines help to illustrate the growth of craft brewers in the United States and also offer insight and a foundation for helping appreciate the hundreds of beer types brewed for the beer lover,” said Charlie Papazian, president of the Brewers Association.
