The Brewers Association’s beer style guidelines reflect, as much as possible, historical significance, authenticity, or a high profile in the current commercial beer market. Often, the historical significance is not clear, or a new beer type in a current market may represent only a passing fad and is quickly forgotten. For these reasons, the addition of a style or the modification of an existing one is not undertaken lightly and is the product of research, consultation, and consideration of market actualities, and may take place over several years.
Since 1979 the Brewers Association has provided beer style descriptions as a reference for brewers and beer competition organizers. Much of the early work was based on the assistance and contributions of beer journalist Michael Jackson; more recently these guidelines were greatly expanded, compiled, and edited by Charlie Papazian. The task of creating a realistic set of guidelines is always complex. The beer style guidelines developed by the Brewers Association use sources from the commercial brewing industry, beer analyses, and consultations with beer industry experts and knowledgeable beer enthusiasts as resources for information
