Introduced: September 1968
Description
C12C covers the production of beer through fermentation processes and the preparation of its key raw materials. This includes malt production (grain steeping, germination, and kilning), hop processing and conditioning, fermentation technology, and beer clarification or stabilization methods. The classification encompasses brewing equipment design, fermentation control, yeast management, and process parameters specific to beer manufacturing. Adjacent classes distinguish beer production from spirits distillation (C12J) and other fermented beverages like wine or vinegar (C12L).
