We all know that food has a shelf life, but does tea have a shelf life? How long is the shelf life of tea? Tea does have a shelf life, but it depends on the type of tea. Different teas have different shelf lives.

There is no clear regulation on the shelf life of tea. Mingshan Ecological Tea strictly controls the moisture content in its raw materials and production, and adopts advanced preservation technology. Therefore, Mingshan Ecological Tea can generally be preserved for 1-2 hours under sealed packaging at room temperature.

Tea has a shelf life, usually 18 months.

The shelf life of tea is related to the variety of tea, and different teas have different shelf lives. Pu'er tea, black tea, etc. are fully fermented products with a shelf life of up to 10~. Therefore, the country has not set a shelf life for it. Similar teas include Wuyi Rock Tea, Guangxi's Liubao Tea, etc. As long as these teas are stored properly, they will not deteriorate but will improve their quality.

How long is the shelf life of tea? Usually, the shelf life of sealed packaged tea ranges from 12 to 24 months, and the shelf life of loose tea is even shorter. Generally speaking, fresh tea is better. Such as green tea, the shelf life at room temperature is generally about one year. However, the factors that affect the quality of tea mainly include temperature, light and humidity. If the storage method is appropriate and these factors are reduced or eliminated, the tea can be kept for a long time.

There are several ways to judge whether tea is expired: check whether it is moldy or has a stale taste; whether the green tea turns red, the soup turns brown or dark; the concentration, astringency and freshness of the taste decrease; in addition, check the shelf life on the packaging.

The shelf life of Tieguanyin tea is generally about 18 months. Generally, under sealed packaging, the taste of various types of tea will remain unchanged within one year. If it is well stored, there is no problem drinking the tea from the previous year. The storage time varies depending on the type of tea.

There is no clear regulation on the shelf life of tea, and different types of tea have different shelf lives. The key to tea preservation lies in the moisture content of the tea itself and the moisture-proof performance of the packaging materials used for small packaged tea. As long as you use the correct method to preserve tea, it can be preserved for a longer time.
