Oolong (Chinese: 烏龍 → wūlóng) is a traditional Chinese tea somewhere between green (no oxidation) and black (fully oxidized) teas in oxidation. This it is known as semi-oxidized or partially oxidized. Like green, black, and white teas, oolong tea comes from the camellia sinensis plant.
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 notes that typify green tea. It is commonly brewed to be strong, with the bitterness leaving a sweet aftertaste. There are several subvarieties of oolong, with those produced in the Wuyi Mountains of northern Fujian and in the central mountains of Taiwan being among the most famous.
Oolong teas have long been famous for for aiding digestion as well as various other health benefits. While the actual effectiveness of oolong tea's medicinal properties is still to be determined, this tea is certainly an example of human creativity in processing the bounty of nature in a variety of ways to produce novel items for consumption and pleasure.
There are three widely accepted explanations of the origin of the Chinese name. According to the "tribute tea" theory, oolong tea came directly from Dragon-Phoenix Tea Cake tribute tea. The term oolong tea replaced the old term when loose tea came into fashion. Since it was dark, long, and curly, it was called 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 and Oolong) who discovered the tea by accident when he was distracted by a deer after a hard day's tea-picking. By the time he remembered about the tea it had already started to oxidize, but he prepared it anyway, and was delighted with the result.
Oolong is a traditional Chinese tea somewhere between green and black in oxidation. It ranges from 15 percent to 75 percent oxidation. The uniqueness of oolong tea comes from a withering process in the strong sun to remove moisture and then shaking to bruise the edges of the leaves so they oxidize faster than the center.
The leaves for oolong are picked just when they reach their peak, and must be processed immediately.
Oolong tea leaves are prepared in two different ways. Some teas are rolled into long curly leaves, while Anxi and Taiwan teas are pressed into a ball-like form similar to gunpowder tea. The former method of processing is the more traditional.
Oolong tea undergoes a series of delicate processes in order to produce their unique aroma and taste. Typical oolong tea is processed according to the following steps:
While most oolongs can be consumed immediately postproduction, like pu-erh tea, many oolongs benefit from long aging with regular light roasting with a low charcoal fire. Before roasting, Oolong tea leaves are rolled and bruised to break open cell walls and stimulate enzymatic activity. The process of roasting removes unwanted odors from the tea and reduces any sour or astringent tastes; in addition, the process is believed to make the oolong tea more gentle on the stomach.
Tea connoisseurs classify the tea by its aroma (often floral or fruity), taste and aftertaste (often melony). Oolongs come in either roasted (炭焙) or light (密香 or 清香).
Generally, 2.25 grams of tea per 6 ounces of water, or about two teaspoons of oolong tea per cup, should be used. Oolong teas should be prepared with 180°F to 190°F (82°C-87°C) water (not boiling) and steeped 3-4 minutes. High quality oolong can be brewed multiple times from the same leaves, and unlike green tea it improves with reuse. It is common to brew the same leaves three to five times, the third steeping usually being the best.
The most famous and expensive Oolong teas are made here but the production is still usually accredited as organic. A lot of Shuǐ Xiān is grown elsewhere in Fujian. Some of the better known yán chá are:
As the name implies, Dancong ("single bush") teas are clonal or single-bush productions.
Tea cultivation only began in Taiwan in the mid nineteenth century. Since then, many of the teas which are grown in Fujian province have also been grown in Taiwan. Since the 1970s the tea industry in Taiwan has grown at a rapid rate, in line with the rest of Taiwan's economy. Due to high domestic demand and a strong tea culture, the majority of Taiwanese tea is bought and consumed by the Taiwanese.
As the weather in Taiwan is highly variable, quality of tea may differ from season to season. Although the island is not particularly large, it is geographically varied, with high, steep mountains rising quickly from low-lying coastal plains. The different weather patterns, temperatures, altitudes and soil ultimately result in differences in appearance, aroma and flavour of the tea grown in Taiwan. In some mountainous areas, teas have been cultivated at ever higher elevations to produce a unique sweet taste that fetches a premium price.
Oolong tea contains caffeine which stimulates the central nervous system, sharpening thinking skills and improving mental alertness. Along with other teas, there is some evidence that drinking oolong tea reduces the risk of ovarian cancer.
The more heavily oxidized oolong teas have long been famous for for aiding digestion, curing headaches, and cleansing the system of smoke and alcohol. Ooling tea soothes the stomach, acting as a counter balance to rich or greasy food. The lightly oxidized Anxi and Taiwanese oolong teas are viewed by traditional Chinese medicine as beneficial to the respiratory system.
In recent times, oolong tea has been suggested as beneficial for controlling body weight, due to its effect of blocking the absorption of fats and carbohydrates. However, it is not a miracle weight loss ingredient. Rather, drinking oolong tea may support and enhance positive lifestyle changes that support weight loss, such as exercise, sleep, and a balanced diet, leading to faster results.
