This invention discloses a method for processing organic Wuyi rock tea with triple aroma enhancement and high sweetness through heavy fermentation at 51.3℃, belonging to the field of tea processing technology. Using fresh Wuyi rock tea leaves as raw material, after withering and cooling with cold air, the tea undergoes four cycles of ambient temperature withering, each cycle including shaking, static fermentation, and cold air blowing, with the shaking time progressively extended. Then, three temperature-controlled heavy fermentation cycles are performed, with static fermentation at 51.3℃ for 35-45 minutes, and the shaking time progressively extended until the leaves reach a state of three parts red and seven parts green. Finally, a final aroma enhancement shaking is performed, followed by direct fixation. After light pressing, heavy pressing, and light pressing and kneading, the tea undergoes initial drying, cooling, and re-drying to obtain the raw tea. This invention coordinates the oxidation transformation and moisture changes of fresh leaves at different maturity levels, reducing the bitterness of the finished tea, improving floral and fruity aromas, sweetness, and flavor harmony, and enhancing aroma retention and quality stability during storage.
