Camellia sinensis Tea Teh Theaceae

Camellia sinensis, Tea, Teh


Camellia sinensis, Tea, TehAll the worlds tea comes from this camellia species, grown mainly in plantations in the highlands of tropical Asia but also in southern China (its original home) and Japan, and more recently in various other parts of the world where the climate is suitably mild and humid. It normally makes a shrub of 6-10 ft (1.8-3 m) tall with thin, serrated leaves and rather insignificant, white to cream with a hint of lemon flowers about 1 in (25 mm) across borne on recurved stalks from the leaf axils; when grown for tea the plants are kept trimmed to about breast height and flowers are rarely seen. Hardiness zone from 9 To 11
Cultivation: Most camellias grow best in mild, humid climates and some species are very frost tender, but most of the cultivars are moderately frost hardy. They prefer well-drained, slightly acid soil enriched with organic matter and generally grow best in part-shade, though some cultivars are quite sun hardy. Good drainage is important to prevent phytophthora root rot, but they like to be kept moist. There are many varieties suited to pot culture and camellias make handsome tub specimens. Pruning is largely unnecessary, but plants can be trimmed after flowering or cut back harder if rejuvenation is required. Propagate from cuttings in late summer or winter, or by grafting.

According to Chinese mythology, in 2737 BC the Chinese Emperor, Shen Nung, scholar and herbalist, was sitting beneath a tree while his servant boiled drinking water. A leaf from the tree dropped into the water and Shen Nung decided to try the brew. The tree was a wild tea tree.
The modern term "tea" derives from early Chinese dialect words - such as Tchai, Cha and Tay .Known as Camellia Sinensis to Western botanists, tea is an evergreen plant of the Camellia family.
The freshly gathered shoots are collected and a method of withering, rolling fermenting and drying, produces the fine teas.
Black tea makes up 98 percent of the international tea trade and is the familiar coloured tea, flavoured with a delicate aroma and should be without any bitterness. Green tea does not go through the fermenting process and the leaves are heated (roasted in an iron pan or steamed) to prevent fermentation. It makes a pale greenish-yellow tea, which is milder and slightly bitter.
The process of blending takes place after further professional tasting. Usually a blend may be made up of different teas from various tea gardens. The blenderÕs expertise guarantees consistency - to ensure tea picked and packed throughout the year in different seasonal conditions does not vary in quality, aroma or taste.
The tea color is a result of the chemical changes that occur to the leaves when they are given time to oxidize, before drying, during the manufacturing process. Tea leaves that have been given full time to ferment become black tea. Oolong leaves are those that have been given a shorter time to oxidize or semi-ferment. Tea leaves which have been dried without being given time for oxidation or fermentation remain green in color.
Tea easily absorbs moisture and odours and so it is essential that it is kept in a cool dry place away from any strong smelling items. It must be stored in an airtight container not exposed to light and used within a reasonable time.
Today, the consumption of tea is just as important as the consumption of drinking water. On average about 21Ú2 million metric tons of tea are produced worldwide
India and China are the largest consumers of tea on the basis of total leaf used, and this consumption is largely from internal production. These countries are the largest producers of tea, as well.
The UK is the largest per-capita consumer of tea averaging about 3.5 to 4.0 cups per day.
