Beer per se, brewing of beer, fermentation processes and post fermentation treatments for beer are classified in subclass C12C.

C12C deals with the process of making beer with a low alcohol content

Low alcohol beer is classified in C12C 12/04.

Low alcohol of wine is classified in C12G 1/00 and others low alcohol beverages are classified in C12G 3/08.

Post-fermentation treatment such as carbonation is subject matter of this subclass but is classified in C12H when combined with subject matter of that subclass.

When classifying in this subclass, classification is also made in group B01D 15/08 insofar as subject matter of general interest relating to chromatography is concerned.
