What is the shelf life of flower tea

The shelf life of flower tea is generally 12 to 18 months, and the actual time is affected by various factors such as storage environment, packaging method, raw material quality, processing technology, and whether preservatives are added. When stored in a sealed, dark, and dry environment, flower tea can usually maintain its quality for about 18 months. This type of storage condition can effectively slow down oxidation and microbial growth, especially suitable for common varieties such as jasmine tea and rose tea. Flower tea sealed in aluminum foil bags or ceramic jars has a longer storage time than ordinary paper bags. High temperature and high humidity environments can accelerate the volatilization of flower tea aroma and moisture deterioration. Pure natural flower tea without added preservatives has a relatively short shelf life, while flower tea treated with low-temperature drying technology is more resistant to storage than dried tea. Some special flower teas such as chrysanthemum tea and honeysuckle tea may have their shelf life shortened to about 10 months. These types of flower teas contain a lot of volatile components and are easily affected by air after opening. Herbal tea with added sugar or dried fruits usually has a shelf life of no more than 12 months due to the hygroscopicity of sugar. If obvious discoloration, clumping or moldy taste is found in the flower tea, it is not recommended to continue drinking even if it has not expired. Vacuum packaged flower tea can extend its shelf life by 3 to 6 months when unopened.

When storing flower tea, it is recommended to divide it into small portions for use to avoid repeated opening and closing of the packaging, which may cause moisture. Flower tea can be placed in a cool and dry place, away from damp environments such as kitchens, and combined with food desiccants to better maintain quality. Before drinking, pay attention to whether the petals maintain their complete color. If the tea soup becomes cloudy or has a strange smell after brewing, it may have spoiled. Different types of flower tea should not be stored together, and special formula flower tea should strictly follow the shelf life indicated on the packaging.
