Storing them in the fridge helps isolate them from external influences and maintains their stability. However, when…

How to prevent tea from aging and deteriorating: Do well in preventing pressure, dampness, sealing, avoiding light, and preventing odor. Green tea is suitable for canning and sealed refrigeration; black tea needs to be stored in a tightly closed and dry container; Oolong tea can be stored at room temperature using double-lid cans such as iron or tin cans; white tea requires a well-sealed tin or iron can for storage; Pu'er tea should be stored with cotton paper in a normal temperature environment without any odor. How to Better Prevent Tea from Aging? 1. Control of moisture content in tea: The safe moisture limit for tea is below 5%. For coarse tea, if it undergoes one short-term high-temperature drying, it may not achieve complete and sufficient drying, so two-stage drying is more ideal. Freshly dried tea needs to cool down before being bagged, but this cooling time should not be too long to avoid re-moistening; after the coarse processing, picking out stems and dust, the tea must be dried again to ensure that the moisture content is less than 5%. 2. Avoid light exposure. Experiments have shown that light is the most intense and rapid factor leading to deterioration of…

Pu'er tea, due to its post-fermentation characteristics, is not as picky about storage conditions compared to green teas, especially premium ones that require sealed, shaded, and low-temperature storage. For everyday home storage of Pu'er tea in small quantities, there's no need to be overly meticulous; the main considerations are a clean environment, absence of odd odors, shade, ventilation, and dryness. However, if storing larger quantities, attention should be paid. After all, it would be a shame for perfectly good Pu'er tea to suffer in flavor due to improper storage.

There are six main types of tea, and the storage time after opening varies depending on the type. Green and yellow teas can typically be stored for about 2 to 3 months after opening. These types of tea are particularly susceptible to oxidation and should be consumed as soon as possible. Black and Oolong teas can be stored for 6 to 12 months after opening. Dark teas and Pu'er teas can be stored long-term if properly preserved after opening. How Long Can Opened Tea Be Stored? If tea is left unsealed after opening, it can be stored for around 3 months. The key to preserving tea is keeping it dry, sealed, away from light, and free from odors. Leaving opened tea unsealed makes it susceptible to external influences, accelerating the oxidation of its internal components and shortening its shelf life (to around 3 months). If you seal the tea in an aluminum bag and place it in a metal tin, then cover the tin with a plastic bag and tie it securely, you can store it in the refrigerator. How to Store Opened Tea: After opening, store the tea in containers or bags with high airtightness at room temperature. To…

Storing Pu'er tea requires attention to sealing, avoiding light, preventing dampness and off-flavors, while also considering humidity and temperature. When storing, you can use a cardboard box; find a clean cardboard box, put the Pu'er tea inside, and store it in a tea room away from walls and the floor. For individual Pu'er tea cakes, you can use kraft paper bags or aluminum foil bags for storage, seal them well, and then place them in a ventilated area free of moisture. How to Store Pu'er Tea Cakes 1. Pu'er tea cakes are compressed from Pu'er tea leaves. Initially, they were made for convenience in transportation, so the shape and production method of Pu'er tea cakes determine their ability to be stored for a long time.
