1. Choose tea suitable for cold brewing: green tea, white tea, Tieguanyin, Longjing and Biluochun are suitable.

2. Take out a proper amount of tea leaves and put them in a teapot or container.

3. Add cold water, and generally use about twice as much tea as hot water. For example, 300ml of cold water is used for 5 grams of tea.

4. Cover the lid and put it in the refrigerator for about 8 hours.

5. Filter the tea leaves, ice cubes can be added or ingredients such as fruits, mint leaves and lemon slices can be added to enhance the taste and interest.

Water continuation method:

1. In the cold tea pot, the tea soaked all night is exhausted, so it will be lighter to use the refilling water.

2. Adding a new piece of tea to the original tea will make the tea taste more mellow.

Keep the same time as before, but increase the amount of tea, so that the tea tastes more intense. If you like to drink strong tea, you can try this method.

4. If you like to drink weak tea, then you should choose to add water gently, for example, soak it in boiling water, and then pour it into the original tea to mix. The tea made by this method will be milder.
