Longjing tea (simplified Chinese: 龙井茶; traditional Chinese: 龍井茶; pinyin: lóngjǐng chá), also known as Dragon Well tea, is a variety of roasted green tea^[1] from Hangzhou, Zhejiang Province, China where it is produced mostly by hand and has been renowned for its high quality, earning the China Famous Tea title.

According to many tea experts, the Longjing tea is amongst the finest and most representative of green teas.^[2] It has been described as the "ideal" beverage for "quiet, contemplative times."^[3]

Production and Health Content

Like most other Chinese green tea, Longjing tea leaves are roasted ^[4] early in processing (after picking) to stop the natural "fermentation" process, which is a part of creating black and oolong teas. In the world of tea, the term "fermentation" refers to the actions of natural enzymes, present in the leaves, on the juices and tissues of the leaf; this is not "fermentation" in the true sense of the term (as, for example, the action of yeast in producing beer). The actions of these enzymes is stopped by 'firing' (heating in pans) or by steaming the leaves before they completely dry out. As is the case with other green teas (and 'white teas'), Longjing tea leaves are therefore "unfermented." When steeped, the tea produces a yellow-green color, a gentle, pure aroma, and a rich flavor. The tea contains Vitamin C, amino acids, and, like most finer Chinese green teas, has one of the highest concentrations of catechins among teas.^[5]

Preparation

For best infusion results, water at around 75 °C should be used to brew the tealeaves.^[1][6]

Although it is common practice nowadays to steep Longjing tea in porcelain or glassware, the real taste profile of a finer Longjing is achieved only by using a genuine Yixing clay teapot, which since the beginning, was popular exactly for preparing green tea well.^[7]

Quality

The tea can be very expensive,^[8] and the prices depend on the varieties, which there are many.^[8] Longjing is divided into seven grades: Superior, Special, and then 1 down to 5. Infused leaves are a good indicator of quality, which is characterized by maturity and uniformity of the shoots harvested for processing. High quality Longjing teas produce tender, whole leaves that are uniform in appearance. Lower quality varieties may vary in color from bluish to deep green after steeping. Before infusion, higher quality Longjing teas have a very tight, flat shape and light green color. A study by Wang and Ruan (2009) found that one aspect of the perceived low quality of Longjing teas was a higher concentration of chlorophyll, producing a darker green color. The study revealed that free amino acids and theanine concentrations contribute positively to what is perceived as a good taste.^[9]

Legends

Longjing tea was granted the status of Gong Cha, or Imperial tea, in Qing Dynasty by Chinese emperor Kangxi. According to the legend,^[10] Kangxi's grandson Qianlong visited West Lake during one of his famous holidays.

He went to the Hu Gong Temple under the Lion Peak Mountain (Shi Feng Shan) and was presented with a cup of Longjing tea. In front of the Hu Gong Temple were 18 tea bushes. Emperor Qianlong was so impressed by the Longjing tea produced here that he conferred these 18 tea bushes special imperial status. The trees are still living and the tea they produce is auctioned annually for more money per gram than gold.^[11]

There is another legend connecting Emperor Qianlong to Longjing Tea. It is said that while visiting the temple he was watching the ladies picking the tea. He was so enamored with their movements that he decided to try it himself. While picking tea he received a message that his mother, the Empress Dowager was ill and wished his immediate return to Beijing. He shoved the leaves he had picked into his sleeve and immediately left for Beijing. Upon his return he immediately went to visit his mother. She noticed the smell of the leaves coming from his sleeves and he immediately had it brewed for her. It is said that the shape of Longjing Tea was designed to mimic the appearance of the flattened leaves that the emperor brewed for his mother.^[11]

Longjing, which literally translates as "dragon well," is said to have named after a well that contains relatively dense water, and after rain the lighter rainwater floating on its surface sometimes exhibits a sinuous and twisting boundary with the well water, which is supposed to resemble the movement of a Chinese dragon.

Legend also has it that to achieve the best taste from Longjing, water from the Dreaming of the Tiger Spring, a famous spring in Hangzhou, is to be used. The water quality of the spring now is certainly very different than before.

Authentic Longjing

There are various definition of Longjing; however a common definition is that authentic Longjing at least has to come from the Zhejiang province in China,^[12][13] with the most conservative definition restrict the type to the various villages and plantations in the West Lake area in Hangzhou.^[14] A large majority of Longjing tea on the market however is actually not from Hangzhou, Zhejiang. Credible sellers may sometimes provide anti-fake labels^[15] or openly state that the tea is not from Zhejiang. Many of these inauthentic longjing teas are produced in provinces such as Yunnan, Guizhou, Sichuan, and Guangdong.

It is actually quite easy to tell if Longjing Tea is authentic and that is by taste and smell. The aroma and flavors of the inauthentic Longjing Teas are nowhere near as complex, or longlasting as the authentic tea. These teas, although similar in appearance are mild in flavor and aroma and do not have the long lasting aftertaste of the original.^[16]

Some tea makers take fresh tea leaves produced in Yunnan, Guizhou and Sichuan provinces and process them using Longjing tea techniques; and some merchants mix a small amount of high grade with low grade tea, and sell it as expensive high grade.

Varieties

Examples of Xi Hu Longjing

Xi Hu Longjing

This is an example of the very standard convention of naming; the Xi Hu (West Lake) is a place where this particular Longjing is grown. This Longjing, also known as West Lake Longjing, is a China Famous Tea—in fact the most famous one—and is grown in the Zhejiang Province near Xi Hu lake. It is grown in a designated area of 168 square kilometers. Historically, Xi Hu longjing tea was divided into four sub-regions: Lion (Shi), Dragon (Long), Cloud (Yun) and Tiger (Hu). As the distinction between the sub-regions blurred over the years, this categorisation has now been adjusted to Shi Feng Longjing, Mei Jia Wu Longjing, with the remaining known collectively as Xi Hu longjing, although the Lion variety is still considered the "crème de la crème" by connoisseurs.

Bird's Tongue Longjing

First growth picked on March 21 yields a more intense aroma and taste of sweetness than the better known Ming Qian Longjing. Supply solely depends on yearly climate; therefore it can be expensive. It is not necessarily more expensive since you will need less for the cup.

Ming Qian Longjing

Pre-Qingming Longjing

The premium early season first-picking known as Ming Qian or Pre-Qingming (or Before Ching Ming) Longjing tea requires it to be produced from the very tender first spring shoots prior to the Qingming Festival on the 5th of April each year (approximately). The production cycle is very short, only ten days before Qingming every year. Tea picked after this period is of a lower grade called Yu Qian Longjing (雨前龍井), or "Dragon Well Before the Rain". In the 10-day span when Ming Qian Longjing is produced, the sprouts at the tip of the stalks are only hand-picked by experienced workers, and then specially processed; as a result, Pre-Qingming Longjing is more expensive than "standard" Longjing tea.

Shi Feng Longjing

A type of Xi Hu Longjing. Fresh tasting, its fragrance is sharp and long lasting. Its leaves are yellowish green in color. Some unscrupulous tea makers excessively pan-fry their tea to imitate its colour.

Mei Jia Wu Longjing tea, sold in Shanghai

Mei Jia Wu Longjing 

A type of Xi Hu Longjing. This tea is renowned for its attractive jade green color. Early teas can fetch up to 6000 yuan per kilogram (2005 data) direct from the growers.

Bai Longjing

Not a true Longjing but looks like one and is commonly attributed, it is actually a Bai Pian. It comes from Anji in the Zhejiang Province. It was created in the early 80's and is a Green tea from a race of White tea trees and is hence very unusual; it is said to contain more amino acids than ordinary Green tea.

Qian Tang Longjing

This tea comes from just outside the Xi Hu Longjing designated area, in Qian Tang. It is generally not as expensive as Xi Hu Longjing.
