We'd better not use sealed bags to store Pu'er tea at ordinary times, because Pu'er is a kind of post fermented tea, which will be transformed during storage, and the transformation needs the existence of oxygen. We usually keep Pu'er tea in a ventilated and dry place, and then put it in wooden boxes, iron cans and so on. Can we keep Pu'er tea in sealed bags? Pu'er tea is a kind of tea loved by the public. Many people like to store some Pu'er tea at home. Usually people store Pu'er with cans, bottles and other things, but if we don't have these things, can we use sealed bags to replace them?
It is not recommended to use sealed bags to preserve Pu'er tea, because Pu'er tea is a kind of post fermented tea, which means that Pu'er will be transformed in the later storage, and oxygen is needed if this transformation is to occur.
Therefore, when we save Pu'er tea at ordinary times, it is best to put them in a ventilated and dry place and store them in wooden boxes, iron cans and other things, so that Pu'er tea will not deteriorate in the process of preservation, but also can be transformed in the process.
