Storage
Tea has a shelf life that varies with storage conditions and type of tea. Tea stays freshest when stored in a dry, cool, dark place in an air-tight container. Storage life for all types of tea can be extended by using desiccant packets or oxygen absorbing packets, and by vacuum sealing. Improperly stored tea may lose flavor, acquire disagreeable flavors or odors from other foods, or become moldy.
Black tea has a longer shelf life than green tea.
Black tea stored in a bag inside a sealed opaque canister may keep for two years.
Green tea loses its freshness more quickly, usually in less than a year. When storing green tea, discreet use of refrigeration or freezing is recommended. In particular, drinkers need to take precautions against temperature variation.
Some teas such as flower tea may go bad in a month or so.
An exception, Pu-erh tea improves with age.
Gunpowder tea, its leaves being tightly rolled, keeps longer than the more open-leafed Chun Mee tea.
The addition of milk to tea was first mentioned in 1680 by the epistolistMadame de Sévigné. Many teas are traditionally drunk with milk. These include Indian masala chai, and British tea blends. These teas tend to be very hearty varieties which can be tasted through the milk, such as Assams, or the East Friesian blend. Milk is thought to neutralize remaining tannins and reduce acidity.
The Chinese do not usually drink milk with tea. but the Manchurians do, and the elite of the Manchu Dynasty continued to do so. Hong Kong-style milk tea is based on British colonial habits.
The order of steps in preparing a cup of tea is a much-debated topic. Some say that it is preferable to add the milk before the tea, as the high temperature of freshly brewed tea can denature the proteins found in fresh milk, similar to the change in taste of UHT milk, resulting in an inferior tasting beverage.
Others insist that it is better to add the milk after brewing the tea, as most teas need to be brewed as close to boiling as possible. The addition of milk chills the beverage during the crucial brewing phase, meaning that the delicate flavor of a good tea cannot be fully appreciated. By adding the milk afterwards, it is easier to dissolve sugar in the tea and also to ensure that the desired amount of milk is added, as the color of the tea can be observed.
A 2007 study published in the European Heart Journal found that certain beneficial effects of tea may be lost through the addition of milk.
Tea was first discovered by the Chinese Emperor Shennong in 2737 BC. It is said that the emperor liked his drinking water boiled before he drank it, so it would be clean. The phoneme 'tu' (荼) later developed into 'te' in the Fujian dialect, and later 'tea', 'te'.
The first use of the word Cha instead of 'tu' for tea was in Lu Yu's Cha Jing, The Classic of Tea (Cha Jing 茶經) of 760 AD.
Tea leaves were processed into compressed cakes form (brick-tea) , which was ground in a stone mortar. Hot water was added to the powdered teacake, or the powdered teacake was boiled in earthenware kettles then consumed as a hot beverage.
A form of compressed tea referred to as white tea was being produced as far back as the Tang Dynasty (618-907 A.D.). This special white tea of Tang was picked in early spring, when the tea bushes had abundant growths which resembled silver needles. These "first flushes" were used as the raw material to make the compressed tea.
