Oolong (traditional Chinese: ??; simplified Chinese: ??; pinyin: wulÃ³ng) is a traditional Chinese tea (Camellia sinensis) somewhere between green and black in oxidation. It ranges from 10% to 70% oxidation. It is among the most popular types of teas served in typical Chinese restaurants. In Chinese tea culture, semi-oxidized oolong teas are collectively grouped as qingchÃ¡ (Chinese: ??; literally "clear tea"). Oolong has a taste more akin to green tea than to black tea: it lacks the rosy, sweet aroma of black tea but it likewise does not have the stridently grassy vegetal notes that typify green tea. It is commonly brewed to be strong, with the bitterness leaving a sweet aftertaste. Several subvarieties of oolong, including those produced in the Wuyi Mountains of northern Fujian and in the central mountains of Taiwan, are among the most famous Chinese teas. Oolong tea leaves are processed in two different ways. Some teas are rolled into long curly leaves, while some are pressed into a ball-like form similar to gunpowder tea. The former method of processing is the older of the two. The name oolong tea comes into the English language from the Chinese name (traditional Chinese: ???), which is pronounced as OÂ·-liÃ´ng tÃª in the Min Nan spoken variant. The Chinese name means "black dragon tea". There are three widely accepted explanations on how this Chinese name came about. According to the "tribute tea" theory, oolong tea was a direct descendant of Dragon-Phoenix Tea Cake tribute tea. Oolong tea replaced it when loose tea came into fashion. Since it was dark, long and curly, it was called the Black Dragon tea. According to the "Wuyi" theory, oolong tea first existed in Wuyi Mountain. This is evidenced by Qing dynasty poems such as Wuyi Tea Song (Wuyi Chage) and Tea Tale (Chashuo). It was said that oolong tea was named after the part of Wuyi mountain where it was originally produced. According to the "Anxi" theory, oolong tea had its origin in the Anxi oolong tea plant. A man named Sulong, Wulong or Wuliang discovered it. Another tale tells of a man named Wu Liang (later corrupted to Wu Long, or Oolong) who discovered oolong tea by accident when he was distracted by a deer after a hard day's tea-picking, and by the time he remembered about the tea it had already started to oxidize. Organic food is produced by farmers who emphasize the use of renewable resources and the conservation of soil and water to enhance environmental quality for future generations. Organic meat, poultry, eggs, and dairy products come from animals that are given no antibiotics or growth hormones. Organic food is produced without using most conventional pesticides; fertilizers made with synthetic ingredients or sewage sludge; bioengineering; or ionizing radiation. Before a product can be labeled "organic," a Government-approved certifier inspects the farm where the food is grown to make sure the farmer is following all the rules necessary to meet USDA organic standards. Companies that handle or process organic food before it gets to your local supermarket or restaurant must be certified.
