How is tea classified by season?

According to the growth characteristics of tea plants, tea buds can germinate at temperatures above 10 °C. So theoretically, as long as tea buds germinate, they can be picked. According to the season, it can be divided into spring tea, summer tea, autumn tea and winter tea. The southern region, especially Yunnan, Guangdong and other subtropical areas, can basically achieve year-round mining, but in order to ensure the nutritional supply of tea plants and low winter temperature, it will be appropriate to choose not to harvest in winter or less in early winter. Generally, the quality of spring tea is the best of the year. Because tea plants store a lot of nutrients in the roots in winter, they are used for tea bud germination the following spring. The aroma of autumn tea will be better, because the temperature difference between day and night in autumn is large, the temperature is reduced but it is not lower than the temperature of the growth point of the tea plant, so tea buds continue to germinate, and the appropriate low temperature can promote the formation of aromatic substances. Summer tea is generally bitter and has poor taste coordination; Winter tea generally has a light taste. Green tea is particularly seasonal, and green tea spring tea, that is, green tea picked in spring, is of the best quality. The reason is that green tea pursues freshness, and the amino acids of spring tea, especially theanine, are the most abundant time of the year. The freshness of tea is mainly provided by amino acids, and the reason why summer tea is bitter is also because amino acids are reduced and the phenolic ammonia ratio is large. The Mingqian tea and Guyu tea mentioned by the subject are further divided from the twenty-four solar terms. Mingqian tea refers to tea leaves picked before or around Qingming, and tea before rain refers to tea leaves picked before or around Gu Yu. "Mingqian tea, expensive as gold", "one or two spring tea, one or two gold" is derived from this, it can be seen that the quality of spring tea is high, and the price is also high.
