1, smell the fragrance.

Smell the fragrance before drinking tea. The specific way to smell the fragrance is to soak a small amount of green tea in boiling water and smell the fragrance of the soaked tea. Generally speaking, the top grade of green tea is orchid fragrance or magnolia fragrance; If the brewed green tea has a grassy smell, it is mostly inferior, because the grassy smell means that the green tea shows that the tea leaves are not completely immobilized, and there is a great possibility of organic tea, or the tea leaves are not fresh and tender in summer, and all those who smell rancid and musty are deteriorated tea.

Step 2 Look at Bai Hao.

Generally speaking, the more white hair, the better. In addition to the number of white hair, there is also a question of whether white hair is loose. Generally speaking, white hair is best restrained and attached to tea. Because Bai Hao is a layer of fine fluff growing on the back of tea buds, it is white after drying. If it is not allowed to fall off, the tea leaves will appear white. After soaking, Bai Hao still insisted on tea. After the green tea is kneaded, the white hair falls off and dries. After the tea leaves are soaked, the broken white hairs float on the water like an oil film, which proves that the tea leaves are fresh. If the white hair is lost after long-term storage or long-distance transportation, this phenomenon will not happen again. Because other kinds of tea are deeply processed, there will be no white hair.

Step 3 observe the ups and downs

This method can be used to identify whether the purchased green tea is new or old. The specific method is to prepare a cup of 90-degree boiling water and sprinkle a handful of tea leaves in it. If the tea leaves sink immediately, it is new tea, and the old tea will float on it at first.

Step 4 taste

The taste of green tea also varies with the place of origin and the type of tea. They are all sweet, and the strong alcohol is the top grade. The taste is light, and those with bitterness and irritation are not top grade. Although some green teas are slightly bitter, it is best to be bitter first and then sweet. Smells like grass or rancid mildew, even people who are bitter and numb are inferior.
