do chinese tea leaves expire
Tea leaves do expire.
They have a shelf life. The shelf life of different teas is different: green tea and yellow tea have a shelf life of 18 months, black tea has a shelf life of 24 months, and green tea has a shelf life of 36 months. White tea, black tea and Puer tea can be stored for a long time and do not have a clear shelf life.
All teas with a shelf life will expire, but not all teas have a shelf life. Among the six major tea categories, the shelf life of green tea and yellow tea is 18 months, the shelf life of black tea is 24 months, and the shelf life of green tea can reach 36 months.
Only white tea, black tea and Puer tea can be stored for a long time, have no clear shelf life, and become more fragrant and higher in quality the longer they are stored. Of course, if the tea gets damp, mouldy or spoilt during storage, that’s a different matter.
The main factors affecting the quality of tea are temperature, light and humidity. When storing tea, you should avoid high temperatures, direct sunlight, high air humidity and odours, as once the tea picks up other flavours, it will be difficult to remove them.
If it is sealed, will the tea expire?
1. Yes.
2. Whether you open the tea or not, the length of time will affect its freshness, so it will expire.
3. The shelf life of sealed tea is usually 12 to 24 months. Loose tea has a shorter shelf life because the process of leaving it out in the open will absorb moisture and odors, which will not only make the tea lose its original flavor, but also make it more perishable. Like green tea, it is usually best to consume it fresh. The shelf life at room temperature is usually about one year.
4. The main factors affecting the quality of tea are temperature, light and humidity. If these factors can be reduced or eliminated by suitable storage methods, the quality of the tea can be guaranteed for a long time.
