Is Pu'er tea acidic or alkaline?

Pu'er tea is alkaline, but it is mild in nature, warms the stomach without hurting it, can lower blood lipids, and helps lose weight. Generally, ripe Pu'er tea warms the stomach, and people with poor stomachs are not recommended to drink raw Pu'er tea.

Pu'er tea is a kind of health tea. It is neither black tea nor red tea, but Pu'er tea. Generally speaking, if it is properly stored, ripe Pu'er tea can be stored for 8 to 15 years. However, it does not mean that the longer the Pu'er tea is stored, the better it tastes. If it is not stored properly, it will affect the taste of Pu'er tea and even affect its drinking.

Pu'er tea contains lipase, which can decompose fat. Therefore, people who are losing weight can drink Pu'er tea appropriately. Yunnan Pu'er tea has antibacterial effect, and can also reduce inflammation and kill bacteria. In addition, Pu'er tea contains a certain amount of tea polyphenols, which can play an anti-aging role.

Pu'er tea should not be consumed before or after meals, or before going to bed. It is best to drink Pu'er tea at least 3 hours before going to bed. Pu'er tea will dilute saliva and affect food digestion, so you cannot drink Pu'er tea immediately after a meal, nor before a meal, as this will irritate the stomach. Drinking tea can refresh the mind, but drinking Pu'er tea before going to bed will cause mental excitement, thus affecting sleep.

Why does Pu'er tea have white foam when it is brewed?

First, tea leaves contain saponins, which are prone to white foam. Saponins, also known as saponins, are a general term for plant glycosides that can form aqueous solutions or colloidal solutions and soap-like foam. They are an organic chemical component. The saponins in tea leaves dissolve in water to form white foam. In addition, during the rolling process of tea leaves, tea cells are destroyed, and the cell fluid flows out and adheres to the surface of the tea leaves. Even after drying, the product is still there, so white foam will still appear when brewing. Generally speaking, Pu'er tea that is well rolled has less white foam when brewing, so the amount of white foam can also be used as a reference standard for judging the grade of Pu'er tea.

Second, unsanitary conditions during the production of Pu'er tea can also lead to the formation of white foam. In order to make the tea look good and to increase the weight of the tea leaves, some unscrupulous tea factories will add sugar and gypsum powder during the tea making process, so the tea they produce is prone to white foam. Even after the tea has been washed several times, the white foam still exists.
