White tea

White tea is the uncured and unfermented tea leaf. Like green, oolong and black tea, white tea comes from the camellia sinensis plant. White tea is fast-dried, while green tea is roasted in an oven or pan (while kept moving for even curing). Oolong and black teas are fermented before curing.

White tea usually contains buds and young tea leaves, which have been found to contain lower levels of caffeine than older leaves, suggesting that the caffeine content of some white teas may be slightly lower than that of green teas.

White tea is a specialty of the Chinese province Fujian. [Jane Pettigrew, cite web | title="The Tea Companion" | url=http://books.google.com/books?vid=ISBN0762421509 page 129, Running Press Book Publishers (September 7, 2004)] The leaves come from a number of varieties of tea cultivars. The most popular are "Da Bai" (Large White), "Xiao Bai" (Small White), "Narcissus" and "Chaicha" bushes. According to the different standards of picking and selection, white teas can be classified into a number of grades, further described in the varieties section.

History

In hard times, very poor Chinese people would serve guests boiled water if they could not afford tea. Host and guest would refer to the water as "white tea" and act as if the tradition of serving guests tea had been carried out as usual. This usage is related to plain boiled water being called "white boiled water" in Chinese.Kit Chow, cite web | title="All The Tea in China" | url=http://books.google.com/books?vid=ISBN0835121941 page 129, China Books & Periodicals Inc.

Varieties of white tea

Chinese white teas

*Bai Hao Yinzhen (Silver needle): The highest grade of the Bai Hao Yinzhen should be fleshy, bright colored and covered with tiny white hairs. The shape should be very uniform, with no stems or leaves. The very best Yinzhen are picked between March 15 and April 10 when it is not raining and only using undamaged and unopened buds. Fujian Province, China.
*Bai Mu Dan (White Peony): A grade down from Bai Hao Yinzhen tea, incorporating the bud and two leaves which should be covered with a fine, silvery-white down. From Fujian Province, China. (Sometimes spelled Pai Mu Tan.)
*Gong Mei (Tribute Eyebrow): The third grade of white tea, the production uses leaves from the "Xiao Bai" or "small white" tea trees.
*Shou Mei (Noble, Long Life Eyebrow): A fruity, furry white tea that is a chaotic mix of tips and upper leaf, it has a stronger flavor than other white teas, similar to Oolong. It is the fourth grade of white tea and is plucked later than Bai Mu Dan hence the tea may be darker in color. From Fujian Province and Guangxi Province in China

Other white teas

*Ceylon White: A highly prized tea grown in Sri Lanka. Ceylon White tea can fetch much higher prices than black tea from the area. The tea has a very light liquoring with notes of pine and honey and a golden coppery infusion.
*Darjeeling White: It has a delicate aroma and brews to a pale golden cup with a mellow taste and a hint of sweetness. This tea is particularly fluffy and light. A tea from Darjeeling, India.
*Assam White: White tea production in the Assam region is rare. Much lighter in body than the traditional black teas, a white Assam yields a refined infusion that is naturally sweet with a distinct malty character.
*African White: Produced in minuscule amounts in Malawi and Kenya, mostly as silver needles (Yin Zhen) type made of assamensis buds; usually higher in caffeine and richer in flavour than Chinese whites, sometimes approaching yellow teas, and often changing flavours in the cup.
*White Puerh Tea: Harvested in the spring from plantations found high on remote mountain peaks of Yunnan Province, China. Incredibly labor intensive with each step processed by hand, these luxury whites are wonderfully rich in fragrance, and possess an alluring, sweet nectar-like quality.

Potential health benefits

White tea compared to green tea

A study at Pace University in 2004 showed white tea had more anti-viral and anti-bacterial qualities than green tea. [Science Daily cite web | title="White Tea Beats Green Tea In Fighting Germs" | url=http://www.sciencedaily.com/releases/2004/05/040526070934.htm, (May 28, 2004).]

White tea contains higher catechin levels than green tea due to its lack of processing. ["New" white tea, surprisingly, may have a healthful edge. Environmental Nutrition. Sept 2003. FindArticles.com. 10 Dec. 2007. [http://findarticles.com/p/articles/mi_m0854/is_9_26/ai_n18616257] ] Catechin concentration is greatest in fresh, unbroken and unfermented tea leaves. [Linus Pauling Institute: Micronutrient Information Center. [http://lpi.oregonstate.edu/infocenter/phytochemicals/tea/] ] Furthermore, one study examining the composition of brewed green and white teas found that white tea contained more gallic acid and theobromine. [Santana-Rios G, Orner GA, Amantana A, Provost C, Wu SY, Dashwood RH. cite web | title="Potent antimutagenic activity of white tea in comparison with green tea in the Salmonella assay." | url=http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=11448643&dopt=Citation, Mutation Research-Genetic Toxicology and Environmental Mutagenesis, Vol. 495, no. 1-2, pp. 61-74. (22 Aug 2001).]

Caffeine content of green and white teas are similar, though both depend on factors such as the variety of tea, the cut and of the leaf, and the length and method of steeping.

White tea contains less fluoride than green tea, since it is made from young leaves only. [Linus Pauling Institute: Micronutrient Information Center. [http://lpi.oregonstate.edu/infocenter/phytochemicals/tea/] ]

Brewing

Generally, around 2 to 2.5 grams of tea per 200 ml (6 ounces) of water, or about 1.5 teaspoons of white tea per cup, should be used. White teas should be prepared with 80°C (180°F) water (not boiling) and steeped for 2 to 3 minutes. Many tea graders, however, choose to brew this tea for much longer, as long as 10 minutes on the first infusion, to allow the delicate aromas to develop. Finer teas expose more flavor and complexity with no bitterness. Lower grade teas do not always stand this test well and develop bitter flavors or tannins. On successive brews (white teas produce three very good brews and a fourth that is passable), extend the time by several minutes per. The third brew may require as long as 15 minutes to develop well. Temperature is crucial: if it is too hot, the brew will be bitter and the finer flavors will be overpowered.
