Buy new tea and recognize old tea.
The nutrient composition of tea changes during storage, and the sensory quality of tea deteriorates with the extension of storage time, so new tea should be purchased.
Buy spring tea, recognize summer and autumn tea
Spring tea has plump buds, green color, soft leaves and white hair. Compared with summer and autumn tea, spring tea has fresher taste, stronger aroma and more obvious health care function. Spring tea generally has no pests and diseases in the growth process, so there is no need to use pesticides, so the pollution of tea is very small. Therefore, spring tea is the best quality green tea in a year. The contents of amino acids and vitamins in summer tea decreased obviously, while the contents of anthocyanins, caffeine and tea polyphenols increased obviously, and the taste was bitter. Autumn tea has a light taste, poor aroma and yellow leaves.

How to identify old and new tea?
Everyone is willing to drink the new tea of that year. At present, the color, fragrance and taste of tea can make people's teeth and tongue produce saliva, and the fragrance permeates the heart. Here are some ways to distinguish new tea from old tea. Look at the tea leaves. The new tea produced in that year was dry, hard and loose in appearance and bright in color. After a year or two of storage, Chen is tight and soft. Touch the tea. The new tea feels very dry with your hands, and it turns into powder with your fingers. Old tea is soft and heavy and is not easily crushed. Third, all the new tea stems are broken, but Chen is not easy to break. Fourth, the color of the new tea soup is clear and fragrant, while the color of the old soup turns brown and the flavor is extremely poor. The water content of new tea is generally low, while the water content of old tea is high. Tea loses its drinking value when its water content exceeds 10%. When buying new tea, we should pay attention to protecting its color, fragrance and taste. The method is to use No.5 bamboo shell thermos bottle (the inner container should be dry), put the tea into the bottle, seal it with the bottle cap, take a small amount at a time, and then take it after eating, so that you can taste the taste of new tea all year round and keep it light green and fragrant forever.
