1. Green tea. Green tea belongs to non-fermented tea leaves, has no bitter taste, and the longer it is soaked, the more fragrant it is, so it is more suitable for cold soaking. Prepare 3g tea and a glass, preferably with a lid. Mix tea leaves with water at a ratio of 1: 5. After standing at room temperature for 6 hours or refrigerating in the refrigerator for 12 hours, the tea soup can be poured out, and the tea tastes mellow and refreshing.

2. oolong tea. Oolong tea tastes fresh and mellow. When it is soaked in cold water, the taste of tea will not be reduced, but it will be more fresh and fragrant, and the taste will be sweet and bitter. When cold-soaking, tea leaves can be less and lighter, and about 1~15g of tea leaves can be put into a 1L container. Put the cold-soaked oolong tea in the refrigerator for 4 hours before drinking. It can be brewed many times.

3. White tea. White tea has a fresh and elegant aroma and is rich in nutrients. Cold soaking white tea can better lock the nutrients contained in tea and reduce the loss of nutrients. Wash the white tea with cold water first, then pour it into the utensil, cover it, add the cold boiled water, and let it stand for an hour before drinking. It can also be made into iced drinks and put in the refrigerator for two hours.
