The grading of Long Jing discussed here focuses on the national standards created by Chinese government and local standards by Long Jing farmers. Names of grades created by other organizations or individuals are not within the scope of this discussion.
The grading of Long Jing has changed a lot in the past a few decades.
In the old days (before 1995), Xi Hu Long Jing was classified into 13 grades, from
Superior 1, Superior 2, Superior 3, Grade 1... to Grade 10. From Grade 1 to Grade 10, each grade was divided into 5 levels. So there were totally 13 grades and 53 levels. It was the
official and universal way of grading when everything within the tea industry was state-owned. Each year, standard tea samples of all 53 levels were made available as benchmarks to grade Long Jing products collected from tea farmers and to guide the market of Long Jing. It was a nice and strict system. But 53 levels were just too many to be practical for a growing market of luxury tea in China (Long Jing has been the utmost of the luxury tea in China since Qing Dynasty, after being "advertised" by generations of emperors).
Back then, the highest grade Long Jing (higher than Grade 4, or any pre-Qingming tea) was not available in the market for ordinary people to buy. On the other hand, money was not the key to get the best tea. "Connections" were sometimes more important. There were many years when the whole family of us got pre-Qingming Long Jing along with Long Jing of medium grades from my aunt who worked in the Science and Technology Department of Hangzhou. Somehow their office got Long Jing "samples" every year - which basically meant a few kilos for everybody in the office, yet it was called "samples" :-p With our special connection through my aunt, we were lucky to enjoy nice and fresh tea each year. But the amount was small for each person and the tea was seen as very precious.
In 1980s, once my father went to Hangzhou, and bought some
grade 4 long jing - the highest grade then available in market for
ordinary people to buy. Up till these days he still says how much better
the grade 4 Long Jing was than many so-called superior-grade Long Jing products in market today. I don't
believe it's all because of his wrecked memory and nostalgia. Back then, everything went by the universal standards, and a grade 4 was a solid grade 4. Nowadays, many things could be called superior grade with a big price tag - I think I sound like a senior citizen now :-p
In 1995, the grading of Long Jing was simplified to 7 grades, including Superior 1-3, and Grade 1-4. This simplification was partially to make the grading less complicated, and partially because many farmers stopped autumn harvest of Long Jing. Autumn tea of Long Jing was of lower grades than spring tea (and this is true for most Chinese green teas). With increasing living standards of Long Jing farmers and higher labor costs, the lowest grades of Long Jing tea were discontinued.
Today the aforementioned two systems of Long Jing grading are still in the textbooks of tea
institutes and are still used in tea labs of research institutions. But most tea estates and
tea companies are privately owned now. Producers and owners can grade their
tea in any way they wish. In Long Jing, as well as in many other types of tea, I've seen a lot of grade 2 teas from certain producers that are much better than superior grades of some
other producers. So I think nowadays the grading doesn't tell you much about the
tea itself, but tells a lot about the standards of a
Without a centralized, consistent grading system, nowadays a lot of farmers of long jing, bi luo chun and
other green teas use harvest dates to grade their tea - although it's
not a perfectly scientific standards, it's probably more objective. For approximate dates of tea harvest, here is a tea calendar. But please keep it in mind that the harvest dates vary from year to year, depending on weather conditions.
