Differences between two fermentation processes of miang are demonstrated. The filamentous fungi growth-based process: mature tea leaves are used as the raw material (A); the fungal growth step (B); and the appearance of the final product after fungal growth (C). The non-filamentous fungi growth-based process: young tea leaves are used as the raw material (D); fermentation under anaerobic conditions (E); and the appearance of the final product after the fermentation (F).
