Gu Yun: Have friends come from afar, not too happy? It is also a great pleasure in life to brew a cup or a pot of good tea and drink it with friends. So, how should tea brew and drink? An introduction is now made for readers to refer to in their daily lives. (1) "Three elements" of making tea Good tea must have good water and good tea set, but if you only have these, and you don't master the tea making technology, you still can't get good results. The tea technique consists of three elements: the first is the amount of tea, the second is the temperature of the tea, and the third is the brewing time. The amount of tea is the appropriate amount of tea in each cup or pot. The temperature of the tea is to brew tea with boiling water of appropriate temperature. The brewing time contains two layers of meaning. First, the tea is poured into the appropriate concentration and then poured out. Start drinking, and second, some tea leaves should be brewed several times, each time you need to soak. 1. The amount of tea To make a cup of tea or a pot of tea, you must first grasp the amount of tea. There is no uniform standard for each tea used, mainly based on the type of tea, the size of the tea set, and the drinking habits of consumers. There are many kinds of tea, and the teas are different and the dosages are different. Such as brewing red, green tea, tea and water ratio, roughly in the 1:50 ~ 60, that is, put about 3 grams of dry tea per cup, add boiling water 150 ~ 200 ml. If you drink Pu'er tea, put 5 to 10 grams per cup. If a teapot is used, it should be properly controlled according to the capacity. The most used tea is oolong tea, which is almost one-half of the teapot volume and even more. In short, the key to the amount of tea used is to master the ratio of tea to water. If the tea is less water, the taste is strong; if the tea is less water, the taste is lighter. 2. Tea temperature It is advisable to just boil and blister, and the tea scent is good with such water. If the water boils for too long, it is called “water old†by the ancients. At this time, the carbon dioxide dissolved in the water is volatilized, and the fresh taste of the tea is greatly inferior. The water that has not been boiled is called “sweet†by the ancients. It is also not suitable for making tea. Because of the low water temperature, the effective ingredients in tea are not easy to be soaked, so that the fragrance is low, and the tea floats on the surface and is inconvenient to drink. The mastery of tea water temperature depends mainly on what tea to drink. High-grade green tea, especially the famous green tea with various buds, can not be brewed with 100-degree boiling water, generally about 80 degrees. The tea leaves are tenderer and greener, and the brewing water temperature is lower. The tea soup soaked out must be green and bright, and the taste is fresh and refreshing. The tea vitamin C is also less damaged. At high temperatures, the tea soup tends to turn yellow, the taste is bitter (the caffeine in the tea is easily leached), and the vitamin C is destroyed in large amounts. As usual, the water temperature is high and the tea is "hot". To drink a variety of flower tea, black tea and medium and low-grade green tea, you should use 100 degrees of boiling water to brew. If the water temperature is low, the permeability is poor, the effective ingredients in the tea are less leached, and the tea taste is weak. Soaking oolong tea, Pu'er tea and scented tea, each time using more tea, and the tea is thicker and older, you must use 100 degrees boiling water to brew. Sometimes, in order to maintain and raise the water temperature, hot tea set with boiling water before brewing, after pouring, drench the water outside the pot. Minority drinking brick tea requires higher water temperature, breaking the brick tea and cooking it in a pot. Generally speaking, the temperature of tea water is positively correlated with the solubility of effective substances in tea. The higher the water temperature, the greater the solubility, the stronger the tea soup. Conversely, the lower the water temperature, the smaller the solubility, the lighter the tea soup, generally 60 degrees. The amount of warm water leaching is only equivalent to 45 to 65% of the 100-degree boiling water leaching amount. It must be stated here that, as mentioned above, high-grade green tea is suitable for brewing with 80 degrees of water, which usually means boiling water (water temperature up to 100 degrees) and then cooling to the required temperature; if it is sterile raw water , just burn to the required temperature. 3. Brewing time and frequency The time and frequency of tea brewing vary greatly, and are related to the type of tea, the temperature of tea, the amount of tea used, and the habit of drinking tea. For example, use a cup of tea to drink ordinary red green tea, put about 3 grams of dry tea per cup, brew with about 200 ml of boiling water, and cover it for 4 to 5 minutes before drinking. The disadvantages of this kind of bubble method are: if the water temperature is too high, it is easy to boil the tea (mainly refers to green tea): if the water temperature is low, it is difficult to make tea taste; and because of the large amount of water, it is often not enough to be consumed for a while, soaked for too long, the tea soup becomes Cold, color, aroma and taste are affected. The improved brewing method is: after putting the tea into the cup, first pour a small amount of boiling water to the degree of immersion of the tea leaves, cover for about 3 minutes, and then add boiling water to 70% or more to be hot. When you drink about one-third of the tea in the cup, add boiling water, so that the concentration of the tea before and after is relatively uniform. According to the measurement, when the tea leaves are bubbled for the first time, the soluble matter can be leached 50~55%; the second time, the leaching can be about 30%, the third time, the leaching can be about 10%; the fourth time, the bubble There are very few left. Therefore, it is usually appropriate to brew three times. For example, if you drink small, smashed red and broken tea, brew it in boiling water for 3 to 5 minutes, and most of its active ingredients are leached, so you can drink it quickly. Drinking instant tea is also a one-time brewing method. Drink oolong tea with a small teapot. In the case of a large amount of tea (about half a pot), the first bubble will be poured out in 1 minute, the second bubble is 1 minute and 15 seconds (15 seconds longer than the first bubble), and the third bubble is 1 minute and 40 seconds. The fourth bubble is 2 minutes and 15 seconds. That is to say, gradually increase the brewing time from the second bubble, so that the concentration of the tea before and after is relatively uniform. The temperature of the tea and the amount of tea used also affect the length of the brewing time. The water temperature is high, the tea is used more, the brewing time should be short, the water temperature is low, the tea is used less, and the brewing time should be long. How long is the brewing time? The tea soup concentration is suitable for the taste of the drinker. louver fitting light,led louver fitting,mirror louver fitting,led recessed louver fitting,light fitting louver diffuser,louver window fittings,Recessed Louver Fitting Ningbo Wellway Optoelectronic Technology Co.,Ltd , https://www.wellwayopto.com
