The 2015 BJCP Style Guidelines are a major revision from the 2008 edition. The goals of the new edition are to better address world beer styles as found in their local markets, keep pace with emerging craft beer market trends, describe historical beers now finding a following, better describe the sensory characteristics of modern brewing ingredients, take advantage of new research and references, and help competition organizers better manage the complexity of their events.

Many new styles have been added, and some existing styles have been divided into multiple categories or simply renamed. The groupings of styles into categories has a new philosophy that groups styles with similar judging characteristics rather than a common heritage or family name. Do not assume that the same primary characteristic (e.g., color, strength, balance, dominant flavor, country of origin) was used to determine each category grouping; the reasoning was more variable and nuanced. Some changes have been made to allow us to be more agile in making future revisions. Finally, we have provided some additional guidance on how to use the guidelines to reduce the potential for
misuse that we have observed in past editions.

If you are familiar with the 2008 guidelines, note that many category names and numbers are changing. Note that we have added an Introduction to Beer Styles section, just as we have had in the past with Mead and Cider styles. This new section addresses common characteristics of beer, and attributes that are assumed by default to be present or absent unless otherwise noted.
