Yuelu Maojian is produced in Yuelu Mountain on the outskirts of Changsha, Hunan Province, and tea has been produced here since ancient times. It is said that during the Ming and Qing Dynasties, Yuelu Mountain was already a famous place for producing and supplying tea and water. The tea from Yuelu Mountain and the water from Baihe Spring were both very famous tributes at that time. The quality characteristics of Changsha Yuelu Maojian are many curls, dark green and oily, green and slightly yellow soup, clear and bright, long-lasting chestnut aroma, mellow and sweet taste, yellow-green and bright soup color, fat and tender leaf base. Pure water, spring water or tap water should be used to brew Yuelu Maojian, which has a great impact on the tea soup. The combination of different mineral contents in water and tea polyphenols will produce various tea soup flavors; tea heating temperature: such as water temperature, the contact distance between water and tea when water is poured; space temperature: such as season, time difference between morning and evening, whether there is air conditioning, etc.; Tea-drinking mood: The mood and the environment when drinking tea determine the final decision on which tea should be brewed for the tea drinker. Fresh, soft water with low mineral content is preferred. It is advisable to use clean spring water or distilled water. Tap water should avoid the smell of disinfectant. It can be filtered and stored the day before and used to make tea the next day. Generally, tea water should be boiled first, and the water temperature should not be lower than 95°C except for green tea. Tea sets should be made of ceramics. Be sure to wash it before use to avoid odor; scald the tea leaves in boiling water before putting them in to keep them warm and accelerate the extraction of tea flavor. The dosage recognized by the World Tea Review is three grams of tea leaves, poured into 150CC boiling water, and drunk after steeping for five minutes.
