In addition to tea production in China, over fifty countries in the world currently produce tea, and tea varieties are introduced from China for the most part. No matter which kind of tea is, the color is uniform, the tea is moist and bright, the tea is good after being lubricated and fresh, and the tea is dark and dull, which indicates that the tea raw material is old and tender, the process is poor and the quality is poor. The color and luster of the tea not only is the tenderness of the tea, but also has very important relation with the production area and season of the tea trees. The dryness and humidity of tea should be paid attention to besides color, shape, fragrance and taste. Only dried new tea can be stored for a long time, one or two tea leaves are taken to twist slightly, if the tea leaves can be twisted into powder, the dried tea leaves are indicated, on the contrary, the tea leaves are indicated to be affected with damp, and the tea leaves are not only greatly influenced in color, luster, aroma, taste and shape, but also easily mildewed and deteriorated, and are not suitable for purchase.
