The “Five Major Taboos” of Tea Storage
#Tea Knowledge# The “Five Major Taboos” in Tea Storage 1. Avoid Excessive Moisture: When storing tea, it’s best to keep the moisture content between 3% and 5%. If the moisture level exceeds 6%, the tea is prone to spoilage. 2. Keep Tea Away from Strong Odors: Tea has a strong ability to absorb odors. If stored alongside items with intense smells, its quality will be severely compromised. 3. Do Not Store Tea in High-Temperature Environments: Heat accelerates the auto-oxidation of polyphenols and other compounds within tea. The higher the temperature, the faster the tea ages—especially green tea, which may turn yellowish in color and develop an aged aroma. Generally speaking, green teas and lightly fermented oolongs should be refrigerated, while pu’er and post-fermented dark teas do not require refrigeration. Experiments show that at -5°C, oxidation occurs very slowly, and at -20°C, tea virtually does not deteriorate. For home storage, around 10°C is ideal. 4. Avoid Direct Sunlight: Sunlight can cause tea to oxidize and change color, and may also trigger photochemical reactions that produce unpleasant odors. Particularly with high-grade green teas, exposure to direct sunlight can lead to chemical changes in lipids and polyphenols, resulting in reddish tea liquor, bitter taste, and even a fishy smell after brewing. 5. Do Not Leave Tea Exposed for Long Periods: Prolonged exposure to air and light causes internal components to undergo oxidative decomposition and other chemical reactions, diminishing the tea’s original flavor, degrading its quality, and allowing it to absorb external odors. #2022NewYearRenewalSeason# #ThisIsChineseStyle# This article is sourced from Tencent Weibo.

The “Mangshi 7,000-ton Green Food Tea Industrialization and Export Processing Plant Project,” invested in and constructed by the company within its industrial park, covers a total land area of 20,828 square meters and has a total floor area of 13,285 square meters. The project primarily includes one production line for refined green tea and black tea, one production line for Pu’er tea and De’ang sour tea, as well as associated ancillary facilities. The total investment exceeds RMB 55 million, fully financed through the company’s own funds.
