After choosing the right tea, how to make it play its greatest role is also a science. Han Chi said: "Different teas have different methods of preservation, brewing and drinking."
Preservation: Tea leaves are most afraid of moisture and odor. Tin bottles, porcelain jars and colored glass bottles are the best containers for preservation. Secondly, we should use tin cans, wooden boxes and bamboo boxes. Plastic bags and cartons are the worst. The container should be dry, clean and free of peculiar smell. Well-preserved tea should be placed in a dry and ventilated place, not in a damp, high temperature, unclean or exposed place. There must be no irritating articles such as camphor, medicines, cosmetics, cigarettes and washing products in these places. The new green tea of that year can also be sealed and put into the freezer, which can be kept for 3-6 months.
Brewing:
The longest time for washing tea is 15 seconds. "Now everyone likes to wash tea when drinking tea, but I don't approve of excessive washing tea." Han Chi said that we found in the experiment that the leaching rate of effective components in green tea was over 70% and that in black tea was over 60%. In other words, washing tea too much will lose a lot of nutrients. Jiang Heyuan reminded that if tea leaves must be washed, the washing time should not exceed 15 seconds. Green tea and white tea, it is best not to wash. "But there is one exception. People who are sensitive to caffeine can wash it before drinking tea, because the caffeine in it is leached faster than tea polyphenols, and quick washing can remove some caffeine. "
Drinking:
12g per day is the most suitable. Jiang Heyuan suggested that for ordinary people, it is appropriate to drink about 12 grams of tea every day and brew it in 3-4 times. People who eat more greasy food and have a large amount of alcohol and tobacco can appropriately increase the amount of tea. Pregnant women and children, neurasthenia, tachycardia, should be appropriate to reduce the amount of tea. Han Chi reminded that with the popularity of Kung Fu tea, people drink tea "more and more hot", which is very wrong. "People drink tea for health care, but drinking hot tea will increase the incidence of cancer such as esophageal cancer, which is not worth the candle. The best temperature for drinking tea should be about 60 degrees, not more than 70 degrees. "
Besides, you can drink different teas at different times of the day:
Drinking jasmine tea in the morning has a pleasant fragrance and can improve work efficiency; Drink a cup of light green tea in the morning to refresh your mind; Drink a cup of black tea in the afternoon to get rid of difficulties and refresh yourself; Getting together with friends or family at night and making a pot of oolong or Pu 'er will not affect sleep.
We might as well try this arrangement of drinking tea some day. Leftover tea can also exert residual heat. It is no exaggeration to say that tea is full of treasures. As long as it is used well, "expired" tea can also exert residual heat.
First, it is overnight tea. Jiang Heyuan said that there is no harm in drinking overnight tea, but tea leaves are easily oxidized, so there are often refreshments on the cups of overnight tea. In addition, the temperature is high in summer, and tea leaves are easily contaminated by bacteria, moldy and rancid, leading to diarrhea, so it is best not to drink overnight tea in summer. If you don't want to pour it out, you can also use it for the following purposes: 1 Overnight tea is rich in acid and fluorine, which can not only prevent capillary bleeding, but also play a role in sterilization and anti-inflammation, such as oral bleeding and skin bleeding, and can be used for bathing and gargling; 2. Wash your hair with overnight tea to treat scalp itching; Bad breath annoys many people. If you gargle with overnight tea three times a day, you can eliminate the trouble of bad breath.
The second is old tea and tea residue. Longjing and other green tea people pay attention to drinking the new tea of that year. In case they can't finish it, these teas can also play a role: 1. Cooking. When stewing meat or cooking other greasy and fishy dishes, you can put some tea leaves, which can remove oil and greasy; 2. Tea dregs can be dried and put away, and made into tea pillows with old tea, especially suitable for summer use. If the amount of tea is not enough, you can also make a small tea bag and apply it to your eyes, which can alleviate visual fatigue; 3. After the soaked tea leaves are dried, they can be scattered in damp places at home, such as under the bed, which can absorb moisture.
