In terms of shape, the strips of new tea are more compact, while those of old Chaze diverge. In addition, for Longjing tea and Biluochun, new tea has its own obvious characteristics. The former is green with yellow, and there are some spots on the leaves; The latter has fine white hairs on the back of the bud tip.
Looking at its color, new tea is more bright and shiny, while old tea is often darker; After the tea leaves are soaked in boiling water, the new tea is bright and the old tea is yellow and turbid. For example, the color of green tea and new tea is green, and the soup is yellow, green and bright; Black tea and new tea are moist in color, and the soup is red and bright.
Smelling its fragrance, the new tea is full of fragrance, fresh and natural, and the old tea is light and lacks umami flavor. The old tea of individual merchants can have fragrance, but the fragrance of this kind of tea is not pure enough. As long as you are careful, you can usually tell.
Judging from the humidity, new tea is dry and old tea is thick. New tea has just come into the market and has just been fried. Unless the business is fraudulent, it is generally dry goods. Because the old tea has been placed for a long time, the moisture regain will make the tea feel a little heavier, and it will be rubbed by hand without the crunchy rubbing sound.
