The difference between green tea and green tea can be distinguished by whether it is fermented or not. Green tea belongs to semi-fermented tea, but green tea belongs to non-fermented tea. Green tea, also known as oolong tea, is between black tea and green tea. It not only has the sweet and mellow characteristics of black tea, but also has the delicious and rich taste of green tea, which belongs to "cold nature" tea. Its manufacturing feature is that the tea leaves are green and are constantly shaken after manual screening. Because the edges of leaves collided with each other, they were mildewed and oxidized, showing the characteristics of green tea and red tea. So green tea also has the reputation of "green leaves with red edges". When the green degree is moderate, immediately use the method of pan-frying to kill the green, quickly inhibit the mildew and oxidation of tea, and integrate the unique quality characteristics of green degree. The demand for green tea leaves depends on the method of rolling, which makes the tea leaves shrink into strips. Choose this kind of thick, solid and heavy tea, most of the leaves are spiral, and there are vermilion serrations on the edge of the tea, but the leaves are dark green, moist and shiny, and have the fragrance of orchids. Tieguanyin in Anxi, Dahongpao in Wuyi and Oolong Tea in Taiwan Province all belong to green tea. In addition to the best Nanyan Tieguanyin, Dahongpao, the king of tea, and Frozen Top Oolong from Lugu Township, Nantou County, Taiwan Province Province, they are all the best in green tea. And a good frozen top oolong has a strong fragrance similar to osmanthus after brewing. The brewing method of green tea is to open the tea at the water temperature of 100℃, and then brew it with water of 98℃ for 5 times, but the water temperature of 95℃ is the best for the last brewing. The first bubble is 5 seconds, the second bubble is 5 seconds, the third bubble 10 seconds, the fourth bubble is 20 seconds, and the fifth bubble 1 minute. Green tea Green tea is a non-fermented tea. After high-temperature deactivation, it keeps the original green color of young leaves. The tea brewed by green tea is green and clear, with quiet aroma and fresh taste. Green tea is cold and anti-cancer, which belongs to health drink, but people with cold stomach should pay attention to it. The manufacturing characteristic of green tea is that it must go through the process of enzyme fixation, and the tissues of fresh leaves are destroyed by enzyme fixation. After tea was fixed at high temperature, the enzyme was destroyed. Because of the inhibition of enzyme catalysis, the substances contained in tea must change rapidly, and the characteristics of color, aroma and taste of green tea should be combined. Choose green tea with flat appearance, light green and yellowish color, smooth and even tea leaves, clear and transparent tea color, mellow taste and slightly sweet fragrance. High-quality tea like Bi is shaped like a sparrow's tongue, with thin, flat and slightly curly leaves, covered with white hairs, light green, light yellow and oily leaves, lasting fragrance and flowery taste. Tea can be roughly divided into six categories: black tea, black tea, green tea, green tea, white tea and yellow tea. Among the six categories of tea, many people mistake green tea and green tea for the same category, but of course they are different. Because green tea belongs to semi-fermented tea, but green tea belongs to non-fermented tea.
