A tea friend asked if the thickness of the cup wall has an effect on the quality of tea soup. What is the effect on tasting experience when the teacup is heated before drinking?
To explore this issue, it is necessary to set some conditions in advance:
Due to various factors such as material, shape, glaze, and sintering temperature of the teacup, they will have certain effects on the taste of tea soup. Therefore, we set that all other factors such as thickness of the cup are completely identical.

The general principle is that the thinner the cup wall, the better it is for aroma expression. Therefore, Ruo Chen Ou in Chao Shan Kungfu Tea Four Treasures should be a small porcelain cup with a very thin wall. By drinking a small cup of Oolong tea, it not only ensures a high fragrance and rich taste, but also does not become an burden by drinking too much water.
On the other hand, thicker walled teacups are not conducive to showing off the aroma, but are beneficial for showing off a thick soup feeling, suitable for drinking Pu’er ripe tea, black tea and other teas that do not rely on fragrance to win. Therefore, in the process of tasting tea, we should combine different kinds of tea and equip different teacups in order to better show the best effect of tea soup (just like Zu Qianqiu in “Laughing Proudly at Rivers and Lakes”, drinking different wines with different cups).
Regarding the boiling water to heat the cup before tea tasting, I think it has the same effect no matter how thick or thin the wall of the cup is – high temperature not only helps to bring out the aroma more effectively, but also enhances the flavor of the tea soup.

Pour boiling water (100°) into a cup at room temperature and it will lower the water temperature to 80°-90°. Then, pour out the boiling water and replace it with freshly brewed tea. Enjoy while hot for better flavor than if you put hot tea into a cold cup. Give it a try if you’re interested!
From a health and safety perspective, does boiling water burn cups have a sterilization effect? Considering the short duration of its burners, there should not be much effect. On the contrary, the custom of “when guests come for tea, the tea should be new and people should be warm, the tea should be boiled” is a good footnote.
