Tea

3. Tea Production

A new tea-plant must grow for five years before its leaves can be picked and, at 30 years of age, it will be too old to be productive. The trunk of the old plant must then be cut off to force new stems to grow out of the roots in the coming year. By repeated rehabilitations in this way, a plant may serve for about 100 years.

For the fertilization of tea gardens, soya-bean cakes or other varieties of organic manure are generally used, and seldom chemical fertilizers. When pests are discovered, the affected plants will be removed to prevent their spread, and also to avoid the use of pesticides.

The season of tea-picking depends on local climate and varies from area to area. On the shores of WestLake in Hangzhou, where the famous green tea Longjing (Dragon Well) comes from, picking starts from the end of March and lasts through October, altogether 20-30 times from the same plants at intervals seven to ten days. With a longer interval, the quality of the tea will deteriorate.

A skilled woman picker can only gather 600 grams (a little over a pound) of green tea leaves in a day.

The new leaves must be parched in tea cauldrons. This work, which used to be done manually, has been largely mechanized. Top-grade Dragon Well tea, however, still has to be stir-parched by hand, doing only 250 grams every half hour. The tea-cauldrons are heated electrically to temperature of about 25℃ or 74℃. It takes four pounds of fresh leaves to produce one pound of parched tea.

The best Dragon Well tea is gathered several days before Qingming (Pure Brightness, 5th solar term) when new twigs have just begun to grow and carry one leaf and a bud. To make one kilogram (2.2 lbs) of finished tea, 60,000 tender leaves have to be plucked. In the old days Dragon Well tea of this grade was meant solely for the imperial household; it was, therefore, known as “tribute tea”.

For the processes of grinding, parching, rolling, shaping and drying other grades of tea various machines have been developed and built, turning out about 100kilograms of finished tea an hour and relieving the workers from much of their drudgery.

4. Advantages of Tea-Drinking

Tea has been one of the daily necessities in China since time immemorial. Countless numbers of people like to have their aftermeal cup of tea.

In summer or warm climate, tea seems to dispel the heat and bring on instant cool together with a feeling of relaxation. For this reason, tea-houses abound in towns and market villages in South China and provide elderly retirees with the locales to meet and chat over a cup of tea.

Medically, the tea leaf contains a number of chemicals, of which 20-30% is tannic acid, known for its anti-inflammatory and germicidal properties. It also contains an alkaloid (5%, mainly caffeine), a stimulant for the nerve centre and the process of metabolism. Tea with the aromatics in it may help resolve meat and fat and thus promote digestion.

It is, therefore, of special importance to people who live mainly on meat, like many of the ethnic minorities in China. A popular proverb among them says, “Rather go without salt for three days than without tea for a single day.”

Tea is also rich in various vitamins and, for smokers, it helps to discharge nicotine out of the system. After wining, strong tea may prove to be a sobering pick-me-up.

The above, however, does not go to say that the stronger the tea, the more advantages it will yield. Too much tannic acid will affect the secretion of the gastric juice, irritate the membrane of the stomach and cause indigestion or constipation.

Strong tea taken just before bedtime will give rise to occasional insomnia. Constant drinking of over-strong tea may induce heart and blood-pressure disorders in some people, reduce the milk of a breast-feeding mother, and put a brown colour on the teeth of young people. But it is not difficult to ward off these undesirable effects: just don't make your tea too strong.
