List of beer styles: Beer style is a term used to differentiate and categorize beers by various factors including appearance, flavour, ingredients, production method, history, or origin.  The term "beer style" and the structuring of world beers into defined categories is largely based on the work done by writer Michael Jackson in his 1977 book "The World Guide To Beer".  Fred Eckhardt furthered Jackson's work publishing "The Essentials of Beer Style" in 1989.

It is very rich in Vitamin B.  The beer has a rather low alcohol content (usually less than 3%) and is known to have a heavy and distinctly sour aroma.  In appearance, the beer is opaque and light tan in colour.  It has a thick, creamy and gritty consistency (from the maize).

Experimental beer: Experimental beer is beer that is produced in or as a new style, using a new recipe, or as a type of beer that does not fit within present beer style criteria or definitions.  The term also encompasses minor beer styles that are not covered under any of the Beer Judge Certification Program (BJCP) categories, with the exception of Belgian beers.  Such minor beer styles may serve "as an incubator" for new potential categories, and may attain an official category if the style becomes of interest to the general public at a sufficient level.  The Great American Beer Festival has an experimental beer category as a part of its competition, for which awards are given, as does the World Beer Cup, which also provides awards for beers in this category.  The Oregon State Fair has a home brew competition that includes a category for specialty and experimental beers.
