Inside the Longjing Tea Harvest: What Happens in the 72 Hours After Picking
The spring harvest of Longjing tea is one of China's most time-sensitive agricultural events. The leaves must be hand-roasted within hours of picking — and the technique has not changed in 1,000 years.
Every spring, for a window of approximately three weeks, the hillsides around Hangzhou's West Lake become the most valuable agricultural land in China. The Longjing (Dragon Well) tea harvest is underway, and the clock is ticking. The finest Longjing — the tea that emperors drank, that diplomats receive as state gifts, that sells for thousands of dollars per kilogram — must be picked, processed, and roasted within 72 hours. After that, the moment is gone for another year.
Why Longjing Is Different
Longjing (龙井, Dragon Well) is China's most famous green tea, produced exclusively in a small area around Hangzhou's West Lake. What makes it extraordinary is the combination of terroir (the specific microclimate and soil of the West Lake area), the picking standard (only the bud and one or two leaves), and the processing technique (pan-firing by hand). The result is a flat, jade-green leaf with a distinctive chestnut aroma and a clean, sweet taste that lingers for minutes.
The Picking: Before Qingming Is Everything
The most prized Longjing is 'Pre-Qingming' (明前茶, Míngqián chá) — tea picked before the Qingming Festival in early April. These leaves have spent the winter accumulating nutrients and emerge in spring with exceptional concentration of flavor compounds. A skilled picker can harvest only 500 grams of fresh leaves per day — and it takes 4–5 kilograms of fresh leaves to produce 1 kilogram of finished tea. Pre-Qingming Longjing can cost 3,000–10,000 yuan per kilogram.
The 72-Hour Process: From Leaf to Cup
- Hour 0–2: Picking — only the bud and one or two leaves, by hand, in the early morning
- Hour 2–6: Withering — leaves spread on bamboo trays to lose 15–20% moisture
- Hour 6–12: First roasting — master's hands press and turn leaves in a 200°C iron wok
- Hour 12–24: Cooling and sorting — defective leaves removed by hand
- Hour 24–48: Second roasting — lower temperature, longer duration, develops flavor
- Hour 48–72: Final sorting, grading, and packaging
- After 72 hours: Quality begins to decline; the window has closed
The Master's Hands: A Living Thermometer
The hand-roasting technique (炒茶, chǎo chá) is the most critical and most difficult part of Longjing production. The master places their bare hands into a wok heated to 200°C and uses specific hand movements — pressing, turning, flicking — to simultaneously dry the leaves, flatten them, and develop their flavor. The temperature must be maintained precisely: too hot and the leaves burn; too cool and they do not develop properly. An experienced master's hands are calloused and heat-resistant, developed over decades of practice.
"I have been roasting tea for 40 years. My hands know the temperature better than any thermometer. When the leaves smell right, when they feel right, when the sound changes — that is when you know. You cannot learn this from a book." — Master Lu Guoying, Longjing Village tea farmer
The Eighteen Imperial Tea Trees
At the Hugong Temple near Longjing Village, 18 tea trees are protected by iron fences and security cameras. These are the 'Imperial Tea Trees' (御茶, yù chá) — the trees from which Emperor Qianlong of the Qing Dynasty personally picked tea during his visit to Hangzhou in 1751. The emperor was so impressed that he designated these trees as imperial tribute. Today, the tea from these 18 trees is auctioned annually; in recent years, 100 grams has sold for over 100,000 yuan.
How to Brew Longjing Correctly
Longjing should never be brewed with boiling water — the high temperature destroys the delicate flavor compounds. Use water at 75–85°C. Place the leaves in a glass cup (not a teapot — you want to watch the leaves unfurl). Pour a small amount of water first to 'wake' the leaves, then fill the cup. The leaves will stand upright as they absorb water — this is called 'the tea forest.' Drink within 3 minutes. The second and third infusions are often considered the best.
Where to Experience the Harvest
The Longjing harvest season runs from late March to mid-April. Visitors can participate in tea picking at farms in Longjing Village (龙井村) and Meijiawu Village (梅家坞) near Hangzhou's West Lake. Many farms offer picking experiences followed by a roasting demonstration and tea tasting. The China National Tea Museum (中国茶叶博物馆) in Hangzhou provides excellent context. Book in advance — the harvest season is short and popular.
