Is milk tea made from black tea or green tea?

Milk tea can be made with black tea or green tea. Milk tea is a mixed drink of milk and tea, and many types of tea can be used. For example, Mongolian salty milk tea is mostly made of green brick tea or black brick tea, pearl milk tea is mostly made of black tea, and kumquat lemon is mostly made of green tea. Black tea has the characteristics of red soup, red leaves, sweet and mellow taste, while green tea has the characteristics of clear soup, green leaves, and strong astringent taste.

During the processing of black tea, chemical reactions centered on the enzymatic oxidation of tea polyphenols occur. The composition of fresh leaves changes greatly, with tea polyphenols reduced by more than 90%, and new components and aroma substances such as theaflavins and thearubigins are produced. Keemun black tea is the most famous variety.

Green tea retains the natural substances of fresh leaves, including tea polyphenols, catechins, chlorophyll, caffeine, amino acids, vitamins and other nutrients. The green color and tea soup retain the green tone of fresh tea leaves, hence the name green tea.

Why can't green tea be used to make milk tea?

Green tea cannot be used to make milk tea because green tea itself has a light taste and is slightly bitter, and milk tea made with green tea will also taste astringent. Therefore, when making milk tea, black tea or oolong tea is usually used to make the tea base. They do not have the bitterness and sweetness of green tea, and the taste is relatively mild, which can be better blended with milk and sugar.

Commonly used black teas include broken black tea, Assam black tea from India, and Ceylon black tea from Sri Lanka.

Broken black tea is chopped and processed granular tea leaves. The tea soup is bright red and has a stronger tea flavor when used to make milk tea.

Assam black tea is dark brown with a light caramel flavor, while Ceylon black tea is reddish brown with a mint and lily of the valley aroma.

Why can't you drink new green tea right away?

New green tea contains polyphenols, which will irritate the gastrointestinal mucosa if consumed immediately. New green tea should be kept at home for about 15 days before drinking. At this time, the irritating substances in the green tea are oxidized, but the fragrance is not lost, and the taste will be better, making it the most suitable for drinking.

Since the new green tea contains polyphenols, aldehydes, and hydrocarbons that have not been fully oxidized by air, drinking it at this time will irritate the stomach and intestines.

The newly processed new tea not only tastes bad, but also has a weak tea flavor and a relatively light aroma, which is not as mellow as the tea that has been left for a period of time.

If you drink new green tea right away, the tea soup will taste more bitter, and there will be no sweet taste for a long time after it enters the throat.
