When brewing aged high-quality tea, we will find that there will be a very thin layer of oil mist on the surface of tea soup, and a misty mist is swirling above the tea soup, which makes people feel the agility of nature and adds a mystery to the tea soup.
oil fog
This white fog, called "tea" or "soup", is not an impurity, but a manifestation of fat-soluble substances in tea soup.
It means "harmony and prosperity between heaven and earth". The misty gas produced on tea soup is "tea".
How is the teapot formed?
inclusion
The amount of substances contained in tea leaves, there are some fat-soluble substances in tea soup, fatty acids, carotene and some volatile aroma components separated from tea leaves, the specific gravity is relatively light, floating on the noodle soup, which is caused by the large temperature difference between the upper and lower noodles.
Haode Pu 'er tea
The richer the contents, the more substances are removed from the corresponding tea soup. Tea soup is mainly a fat-soluble substance. If the temperature difference between tea and soup is large, fat-soluble substances will easily float on the noodle soup, which is the tea we see. Therefore, the better the raw materials of Pu 'er tea, the easier it is to form "tea".
anaclasis
There is also a physical reason for the formation of tea-the refraction of light. Tea soup brewed with hot water will vaporize when it meets air, and water vapor will rise upwards. When it meets sunlight, the light will reflect the fog emitted by water vapor.
Factors affecting the presentation effect of "tea"
First, the more fat-soluble substances in tea extract, the more obvious the effect.
Second, the darker the soup, the easier it is to compare and the easier it is to be found.
Third, the darker the soup, the easier it is to compare and the easier it is to be found.
Fourth, when the temperature is low and the air pressure is low, it is also easier to produce.
Fifth, the container for soup will also have a slight impact, especially the use of white porcelain utensils.
Small knowledge
Is the more tea, the better?
Tea is only a normal phenomenon affected by various factors, which can be considered as a factor in purchasing tea, but it cannot judge the quality of tea. Relatively speaking, tea with tea bran will taste better, because the soup will be more mellow, or the tea will be cooked thoroughly and the tea soup will be clearer.
Only Pu 'er tea has tea?
The phenomenon of making tea is not a unique patent of Pu 'er tea soup. In the process of drinking tea, it is found that brewing Wuyi rock tea, Yunnan black tea, or other teas with high fermentation degree will also form tea.
