Bì Luó Chūn (碧螺春) — Jade Snail Spring
Bì Luó Chūn (碧螺春) — Jade Snail Spring
Bì luó chūn (碧螺春) is a pre-Qīngmíng green tea from the Dōngtíng mountains on the shores of Lake Tài (太湖), Jiāngsū province, distinguished by its tightly spiralled white-haired leaf, fruit-orchard terroir, and "three freshnesses" aroma (flowers, stone fruit, fresh leaf in a single cup). One of China's ten famous teas, it requires 60,000–70,000 hand-picked shoots per kilogram of finished tea. The name, "jade snail spring," was reportedly given by Emperor Kāngxī during a Qīng dynasty inspection tour; the original folk name was Xià Shā Rén Xiāng (吓煞人香) — "frighteningly fragrant."
Geography and Harvest
Dōngtíng East Mountain (东山) and West Mountain (西山) — peninsulas projecting into Lake Tài — provide the defining growing environment: moderate humidity, morning mist, lake-moderated temperatures, and direct interplanting of tea bushes with fruit orchards (peach, plum, apricot, bayberry). The shared root zone and canopy with fruit trees is credited with the tea's distinctive fruity-floral character.
Harvest is strictly pre-Qīngmíng (明前, before Qīngmíng festival, early April), when buds are smallest and most flavour-concentrated. Top grade: one bud plus one unfurled leaf. Picking by hand, early morning only. Each kilogram of finished tea requires 60,000–70,000 shoots — among the highest labour ratios of any Chinese tea.
The geographical indication (PGI) for authentic Dōngtíng bì luó chūn covers only Sūzhōu's Wúzhōng district (GB/T 18957-2008). Tea labelled "bì luó chūn" from Sìchuān or Zhèjiāng is processed in the same style but lacks the lake-terroir character.
TL;DR: Authentic bì luó chūn = Dōngtíng mountains, Wúzhōng district, pre-Qīngmíng, 60,000–70,000 buds/kg. PGI under GB/T 18957-2008. Interplanted fruit orchards are the terroir source for the stone-fruit aroma.
How is Bì Luó Chūn processed?
Processing done same day as harvest:
- Shāqīng (杀青 — fixation): Fresh leaf in dry preheated wok at 200–220°C; stir-fried continuously by hand 3–5 minutes to halt oxidation
- Róuniǎn (揉捻 — rolling): Temperature drops to 70–75°C; leaf rolled against wok wall, simultaneously dried and shaped into thin spirals
- Tuán bǎo (团炒 — spiral-shaping): Most distinctive step — leaf rolled into small clusters in the palm, then rubbed against wok surface to form tight white-haired spirals; takes 12–15 minutes
- Bèigān (焙干 — drying): Finished at 60–70°C to fix shape and develop final aroma
The tuán bǎo step requires skill to avoid burning; it is the technical bottleneck that separates genuine hand-crafted bì luó chūn from machine-processed imitations.
TL;DR: Four steps, all same day, all by hand. The defining step is tuán bǎo (spiral-shaping by palm) at 70–75°C — this creates the white-haired spirals and cannot be replicated by machine at the same quality.
Flavour Profile
Genuine Dōngtíng bì luó chūn: pale golden-green liquor, intense fragrance of fresh orchid, osmanthus, stone fruit (apricot, peach), and delicate vegetal sweetness. Clean and light with a long sweet finish. No bitterness in properly made spring-harvest tea.
The aroma is traditionally described as "three freshnesses" (三鲜 sān xiān): fresh leaf, fresh flowers, fresh fruit — distinct and simultaneous in a single cup.
If bitterness is present → cause is either summer-harvest material or brewing temperature above 80°C. Lower the temperature or verify the harvest grade.
How to brew Bì Luó Chūn
| Parameter | Value |
|---|---|
| Water temperature | 75–80°C — higher temps destroy aroma compounds |
| Vessel | Glass tumbler or porcelain gàiwǎn |
| Leaf ratio | 3–4 g per 150 ml |
| Pouring method | Water first, then leaf (下投法 xià tóu fǎ) |
| Steep time | 2–3 minutes per infusion |
| Infusion count | 2–3 |
Add water first, then drop in the spirals — this avoids scalding the tender buds. The spirals sink slowly as they absorb water; fully unfurled leaves standing upright indicate high bud quality.
Authenticity
Much of what is sold as "bì luó chūn" comes from Sìchuān or Zhèjiāng leaf processed in the bì luó chūn style. Common signs of non-Dōngtíng origin: lower white hair coverage, longer and less tightly wound spirals, less complex aroma. Authentic Dōngtíng origin carries the Sūzhōu Wúzhōng PGI mark.

FAQ
What is bì luó chūn? Bì luó chūn (碧螺春, "Jade Snail Spring") is a pre-Qīngmíng green tea from the Dōngtíng mountains, Jiāngsū province, China. It is identified by tightly spiralled white-haired leaves, an intense orchid and stone-fruit aroma, and requires 60,000–70,000 hand-picked buds per kilogram.
Why does bì luó chūn smell of fruit? The tea bushes are interplanted directly with peach, plum, apricot, and bayberry orchards on the Dōngtíng mountains. Shared root zone and canopy between tea and fruit trees transfers aromatic compounds to the tea leaf — this terroir cannot be replicated elsewhere.
How do I brew bì luó chūn? 75–80°C water, 3–4 g per 150 ml in a glass tumbler. Add water first, then drop in the leaf. Steep 2–3 minutes. Expect 2–3 infusions. Do not use boiling water — it destroys the delicate aroma.
What is the difference between authentic and imitation bì luó chūn? Authentic Dōngtíng bì luó chūn (PGI GB/T 18957-2008) comes from Sūzhōu's Wúzhōng district. Imitations from Sìchuān or Zhèjiāng use the same rolling technique but lack lake-terroir character. Signs: less white hair, longer looser spirals, simpler aroma.
When is bì luó chūn harvested? Strictly before Qīngmíng festival (early April). This pre-Qīngmíng (明前) window lasts 2–3 weeks. Later harvests produce a coarser leaf with less concentrated flavour. The earliest buds command the highest prices.
