Judging from the color of the soup, the West Lake Longjing is bright as a green tea soup, especially the tea before the Ming Dynasty, which is slightly weaker before the rain and slightly darker after the rain because of its strong tea nature. Here, I also want to say, don't brew Longjing immediately with just boiled water. It is easy to brew Longjing directly with freshly boiled water, but it is bright at the moment of brewing, so there is no need to dim it later. It is best to use mineral water bubbles. Tap water is not as good as before, especially in big cities, where sewage is pumped back to make tap water before it seeps through. If there is a white stain on the cup that has been drinking tea, it is not your mouth that is dirty, but water. There are also some photos of online stores that are either soaked in a few pieces of tea or the color of PS is distorted, which will not be the effect you bought back at all. Be wary of these shops. I'm sorry, I said where I thought of it! In fact, in the process of transportation and packaging, even a pinch of tea leaves, no matter how well screened, will produce certain fragments, which can be seen when soaked. On the other hand, it affects the color of soup, that is, the color of tea. Tea has just been said, which is inevitable. Big tea companies will carefully screen and blow some ultra-high-end teas, but beauty and nutrition must be chosen. Finally, from the perspective of aroma, tea aroma is an important feature to judge new tea and old tea. On the one hand, it is the aroma of dry tea. In fact, the aroma of dry tea is easier to smell than that of tea before rain, because the leaves of tea before rain grow up and carry more aroma, while tea before rain is more expensive than buds, and buds are more reflected in the brewed tea soup. The dry tea flavor of Qianming Tea is somewhat restrained. On the other hand, there is the fragrance of tea soup. Newly brewed tea is generally fragrant, and West Lake Longjing is generally fragrant with beans. After the tea leaves are all wet, the fragrance is in the soup. The taste of good Longjing soup should be fresh and refreshing first. Whether it is sweet or not depends on one's tongue. We know what good tea is in our market, but fortunately, many people can't say it.
