Puer Tea Industry Uses Wet Storage to Age Tea and Pass It Off as Old Tea

7 November 2026, Hong Kong Economic Times · Life report: Old tea in the Puer tea world is sought after for its unique pharmacological effects, but unscrupulous tea merchants use the "high temperature and high humidity" wet storage environment to artificially accelerate the fermentation of tea leaves, then sell mouldy "aged tea" as old tea. The report pointed out that this practice speeds up the ageing of tea leaves in wet storage, allowing mouldy tea leaves to be passed off as old tea of considerable age. The report only mentions this phenomenon and does not state which merchants are involved, specific quantities or regulatory follow-up.
