180,000 yuan West Lake Longjingtou Tea!
20 12 in March, 500 grams of West Lake Longjingtou tea sold for a sky-high price of 18000 yuan at the pre-sale charity sale of West Lake Longjingtou tea, but according to the market price of gold that day, it only reached 168500 yuan. Tea is as expensive as gold before tomorrow, worthy of the name!
Why do you say "tea is as expensive as gold before tomorrow"?
Qianming tea is a kind of tea picked before Tomb-Sweeping Day. It is a good tea with few pests, tender buds and leaves, fragrant color, mellow taste and beautiful appearance. At the same time, because the temperature before Qingming is generally low, the number of germination is limited, the growth rate is slow, and the yield that can meet the picking standard is very small, so there is also a saying that "tea before Qingming is as expensive as gold". Tea culture experts said that in Jiangnan tea area, after a long winter, the nutrients in tea trees have been fully accumulated, and the temperature is low in early spring, and the growth rate of tea trees is slow. At this time, the bud quality is better.
How to distinguish tomorrow tea from rain tea?
Tea before the Ming Dynasty and tea before the rain are the names of spring tea in different stages of Jiangnan tea area in the Yangtze River basin in China according to the solar terms.
"Tea before tomorrow" is the tea picked in Tomb-Sweeping Day. The tea before tomorrow is tender and of good quality, and the tea before rain is of good quality.
"Tea before rain" is the tea picked after Tomb-Sweeping Day and before Grain Rain. Tea after Grain Rain and before long summer is generally coarse and old with poor quality.
Distinguish between tea before tomorrow and tea before rain:
I. Selection Time and Time to Market
The picking time of West Lake Longjing tea before the Ming Dynasty is of course before the Qingming Festival, and due to global warming, the listing time of West Lake Longjing tea before the Ming Dynasty is getting earlier and earlier. Basically, the West Lake Longjing tea before tomorrow has been listed in March. Before the rain, West Lake Longjing tea, also known as spring catechu, is usually picked in front of Grain Rain after the Qingming Festival and usually listed in April and May.
Second, the external characteristics are different.
The tea leaves of West Lake Longjing new tea before the Ming Dynasty are thick, short and tender. The buds of the new tea before the Ming Dynasty are like the hearts of lotus seeds, so this kind of tea is sometimes called lotus seeds. On the other hand, before the rain, the tea leaves of West Lake Longjing Tea were thin, long and old. This kind of tea has not only buds, but also a flag gun with one bud and one leaf or a tongue with one bud and two leaves.
Third, the content of nutrients is different.
Compared with the West Lake Longjing tea before the Ming Dynasty, the West Lake Longjing tea before the rain has higher nutritional content. The main reason is that the temperature rises quickly after Qingming, the buds and leaves grow faster and the accumulated inclusions are richer, so the West Lake Longjing tea is more resistant to soaking before rain.
How to identify true and false tea before tomorrow?
How to distinguish the authenticity of tea before the Ming Dynasty is very particular.
If it is before Qingming, it must be tea before Qianming, but it is not necessarily Longjing before Qianming produced in Xihu District. In terms of price, Xihu District is much higher.
Longjing can be divided into morning and evening. In the past, only spring buds were used to make Longjing. The picking period from Qingming to Grain Rain took only one season. 1 year ends in May, and Longjing tea is not needed in summer and autumn.
The modern "West Lake Longjing" is picked four times a year in spring. The first kind of tea picked before Qingming Festival is called "Qianming Tea", and its tender buds are like lotus plumule, so it is also called "lotus plumule". According to the standard of super Longjing, there are at least 60,000 tender buds in the lotus plumule fried by 0.5 kg.
Tea picked in front of Grain Rain is called "tea before rain", also known as "spring catechu".
Long Xia Zhishi, known as "Sanchun Tea". At this time, the tea bud developed greatly, with two leaves, which looked like a sparrow tongue, so it was also called "sparrow tongue".
"Sanchun tea" is called "rejuvenation tea" after being picked for one month. At this time, tea has been sliced with tea stems, so it is also called "stem slices", and its quality is not as good as the first three.
From this point of view, the quality of tea is different at different picking times, and of course the price is also very different. No wonder many tea merchants make a fuss about "before tomorrow" and "before rain". This is what people who drink tea should pay attention to.
People who haven't drunk before are basically difficult to tell apart. Regular drinkers can still tell the difference between the two. The real Longjing looks smooth and flat, with green color and brown rice yellow. The taste is slightly floral but the aroma is rich in layers, and it is sweet after the entrance.

Solar Terms and Tea Picking in China
The twenty-four solar terms of the lunar calendar is a supplementary calendar for guiding farming in ancient China, and it is the crystallization of long-term experience and wisdom of working people in ancient China.
The 24 solar terms are: beginning of spring, Rain, Sting, Equinox, Qingming, Grain Rain, Changxia, Xiaoman, Mangzhong, Summer Solstice, Xiaoxia, Daxia, beginning of autumn, Chushu, Bailu, Autumn Equinox, Cold Dew, First Frost, beginning of winter, Light Snow, Heavy Snow, Winter Solstice, Slight Cold and Severe Cold.
In China, every15th day of the lunar calendar is a solar term, which is about "fright" on March 5th, "vernal equinox" on March 20th, "Qingming" on April 5th, "Grain Rain" on April 20th and "long summer" on May 5th.
Ancient agricultural production has always been guided by solar terms.
So is tea production. Early-developed varieties often germinate at the time of "fright" and "vernal equinox", and tea can be picked before "Qingming". The quality of Qianming tea is very good because of its tender buds and rich aroma and taste substances. However, before Qingming, the temperature was generally low, the germination was limited, the growth rate was slow, the yield that could meet the picking standard was very small, and things were rare, so the tea before Qingming was more precious.
In ancient times, tribute tea was early and expensive, so spring tea was divided into three types: "tea before society", "tea before fire" and "tea before rain".
Sheqian refers to the fifth five-day sacrifice to the land god before the ancient Spring Festival Society and after beginning of spring, which is called Shetian. According to the arrangement of branches, the social day is generally between 465 and 438+0 ~ 50 days after beginning of spring, about the spring equinox (around March 20), that is, half a month earlier than Qingming, so the tea harvested in this spring equinox season is more delicate and precious. The purple bamboo shoot tribute tea that was required to be transported to Chang 'an every Qingming Festival in the Tang Dynasty in China should belong to "pre-social tea".
Before the fire, that is, before the Ming Dynasty, it was called "cold food" because the ancients had the custom of forbidding fire for three days on the Cold Food Festival and not cooking for three days. Cold Food Festival is the day before Tomb-Sweeping Day, so "tea before fire" is actually "tea before tomorrow". In the Qing Dynasty, Emperor Qianlong went down to the south of the Yangtze River to watch the collection of Longjing tea in Hangzhou, and wrote a poem entitled "Watching the collection of tea and making songs". There is a poem that says "before the fire is tender, it is best to ride after the fire", which means that the Longjing tea picked in Tomb-Sweeping Day the day before is of the best quality, too early and too tender, too old and too late.
Before the rain, that is, before Grain Rain, that is, after April 5 to April 20, the harvested tea leaves are called tea before the rain. Although tea before rain is not as delicate as tea before tomorrow, tea before rain is often fresh, thick and bubble-resistant, because the temperature is higher, the buds and leaves grow relatively fast and the accumulated inclusions are rich.
Protection scope of geographical indication products of Longjing tea
According to the history and present situation of Longjing tea, it is determined that there are 12 counties (cities, districts) in Xihu District, Yuhang District, Lin 'an City, Fuyang City, Xiaoshan District, Tonglu County, Chun 'an County, jiande city, Shaoxing County, Zhuji City, Shengzhou City, Xinchang County and Shangyu City, which are adjacent to Shaoxing. Longjing tea production is divided into three major producing areas: Longjing tea West Lake producing area, Longjing tea Hangzhou producing area and Longjing tea Shaoxing producing area.
