Why is there a small hole in the lid of the teapot?

The small holes in the teapot cover are used to balance the air pressure acting on the inner and outer water surfaces of the teapot and to suck in air. If the lid is airtight when pouring water, the air in the teapot is insufficient, and the spout will be blocked by the outside atmosphere, so it is impossible to pour water. There is a small hole in the lid of the pot. Air enters the pot from the small hole, which is in balance with the atmospheric pressure of the spout, and the water can be poured out.

There are three kinds of water holes in teapot: single hole, mesh hole and honeycomb hole. Generally, small pots are single-hole, which is easy to be blocked by the bottom of leaves after soaking, which makes the water "flow" not smooth, especially the trumpet-shaped holes need to be dredged with tea needles, so its "flow" is straight.

You must choose the right container for making tea.

1, green tea

Delicate and precious green tea, such as West Lake Longjing, Dongting Biluochun, Junshan Yinzhen and Huangshan Mao Feng, is suitable for soaking in transparent glasses, which is convenient for observing the process of tea slowly stretching, swimming and changing in water. People call them "te amo".

Middle and high-grade green tea, such as first-and second-grade fried green tea, pearl tea and baked green tea, focuses on tasting or quenching thirst, and can be soaked in porcelain cups. Low-grade green tea contains a lot of cellulose, which is resistant to brewing and rich in tea fragrance, and is suitable for soaking in teapot. If you use a teapot to soak and drink exquisite tea, it will suffocate the tea and make it lose its fresh fragrance because there is much water and it is not easy to cool.

2. Black tea

In general, white porcelain or glass-covered bowls are generally used to brew high-grade Kung Fu black tea and small-sized black tea. On the one hand, the soup color of high-grade black tea requires red, white or ivory porcelain to truly reflect the soup color of black tea, which is convenient for tea drinkers to watch. On the other hand, brewing with a covered bowl can give full play to the inherent aroma and taste of black tea without destroying the quality of tea, which is very convenient for tea tasting and smelling.

For strip black tea, teapot brewing is a good choice, which can make the taste of black tea more mellow and lasting. In addition, using the same teapot for a long time to brew the same kind of black tea can also increase the aroma and make it more intense. For black or broken tea, we might as well use a white porcelain pot. Its biggest feature is that it can give full play to the rich and fresh aroma of tea, but the pot-soaking method is not good for aroma.

3.oolong tea

Oolong tea is mainly divided into four categories: southern Fujian oolong (such as Tieguanyin), northern Fujian oolong (such as Dahongpao), Guangdong oolong (such as Dan Cong) and Taiwan Province oolong (such as frozen top oolong). For Minnan Oolong, especially Tieguanyin, besides tasting tea soup, it is also important to smell the fragrance and enjoy the bottom of the leaves. Brewing in a covered bowl is especially convenient for tea drinkers to observe the bottom of leaves and smell the fragrance.

For Wulong in northern Fujian and Wulong in Guangdong, brewing in a bowl can highlight the original flavor and aroma of tea and facilitate the observation of the bottom of leaves. Brewing in a teapot can make the tea soup full of fragrance. It is generally recommended to choose a flat-walled teapot to store old tea in order to maximize its taste. Teapots should be specially designed for brewing, and it is not allowed to brew several kinds of tea in one pot, otherwise the tea tastes bad.
