Biluochun is one of China’s most famous green teas, but the right buying window matters as much as the garden it comes from. Harvest timing changes flavor, grade, price, and shelf strategy for importers, tea shops, and private-label brands. If you buy too early, you may pay a premium before finished lots are ready. If you buy too late, you may end up with a lower-grade harvest or tea that has already started to fade. This guide explains how the Biluochun spring season works and when to buy for freshness, value, or bulk supply.
What Biluochun Harvest Season Actually Looks Like
Authentic Biluochun comes from the East Dongting Mountain and West Dongting Mountain areas near Taihu Lake in Suzhou, Jiangsu. These are not the same Dongting as Dongting Lake in Hunan, which is a common sourcing confusion. The Suzhou microclimate, misty lake air, and early spring bud growth give Biluochun its distinctive tight spiral shape, dense white tips, and floral, chestnut-sweet aroma [2].
The main harvest is spring, usually starting in late March and peaking through the first half of April. For most years, the harvest winds down by late April or early May, although warm or cool weather can move the calendar by a week or more. Two traditional dates anchor the buying season:
- Qingming, around April 4–5, separates the famous pre-Qingming “Mingqian” tea from later spring picks.
- Guyu, around April 20, marks the end of the early-spring premium phase. Tea picked between Qingming and Guyu is called “Yuqian.”
Under the Chinese national standard GB/T 18957, Dongting Biluochun is defined by origin, processing, and sensory requirements, including harvest quality and bud-to-leaf ratio [1]. This is important for buyers: a tea labeled “Biluochun” may simply be a Biluochun-style green tea from another province, not the protected Dongting product.
Best Time to Buy Biluochun Tea by Buyer Goal
The right time depends on what you are sourcing.
| Buyer goal | Best window | Why |
|---|---|---|
| Peak-grade specialty retail or gifting | Late March through Qingming | Small buds, high aroma, soft texture, strongest market story |
| Balanced quality and cost | Qingming through Guyu | Still fresh spring tea, more body, lower premium than Mingqian |
| Value buying and bulk blending | After Guyu through mid-May | More mature leaves, bolder flavor, much lower unit cost |
| Reserved wholesale lots | February to early March | Secures allotment before harvest, but samples must be approved after processing |
For peak-grade Mingqian Biluochun, the practical sequence is to request pre-harvest samples as soon as the first lots are finished, often within a few days after picking. Do not commit to a full container before tasting the current year’s lot, because early-spring weather can make the same garden taste noticeably different from previous years.
For most B2B buyers who need consistent quality across a year, the Qingming-to-Guyu window offers the most useful balance. The leaves are still young and clean, the price has already softened from the very first Mingqian peak, and there is enough volume to build a stable product line.
Harvest Timing, Grade, and Flavor
Harvest timing is the largest driver of Biluochun grade and price. Earlier-picked buds are smaller, more tender, and more labor-intensive. Later-picked leaves are larger and easier to produce, so they cost less and taste stronger.
| Harvest window | Typical leaf standard | Flavor profile | Market position |
|---|---|---|---|
| Pre-Qingming | Bud and one tender young leaf | Sweet, delicate, high florality, soft umami | Premium retail and luxury gifting |
| Qingming to Guyu | Bud with one to two young leaves | More body, chestnut or light nutty notes | Everyday premium and specialty wholesale |
| Post-Guyu | Larger leaves with visible stems | Bolder, less delicate, more astringency | Volume blends, foodservice, cost-sensitive lines |
In general, Mingqian Biluochun carries the highest price, and prices drop through Guyu and the late-spring period. The gap is not small: a top pre-Qingming lot can trade at a substantial multiple of a post-Guyu lot from the same region. The exact premium varies by year, harvest volume, and supplier, so it is best to compare finished samples rather than rely on a fixed price assumption.

How to Verify a True Spring Biluochun Lot
Not every “new season” label means the tea was picked this spring. Use these checks when comparing suppliers:
- Ask for the harvest date, not the packaging date. Tea picked in late March may be packed weeks later, so the lot card should show both.
- Check the origin statement. Protected Dongting Biluochun should cite the Suzhou Dongting Mountain production area under the GB/T 18957 framework [1].
- Look at dry leaf and color. Fresh spring Biluochun usually has a bright, lively green tone with fine white tips and a tight curl. Dull or browning leaf can indicate old stock or poor storage.
- Request a tasting sample against a grade reference. The difference between Mingqian and late-spring Biluochun is usually visible in the brewed leaf, aroma, and mouthfeel, not only on a spec sheet.
- Confirm storage conditions. Biluochun is a green tea, so cold or climate-controlled storage matters. If a supplier cannot describe storage, treat “fresh” claims with caution [3].
A serious wholesale supplier should be able to give you a lot number, origin, harvest date, and a current cupping note. If those details are missing, you are probably being quoted on generic Biluochun-style tea rather than a verifiable spring lot.
Timing Mistakes That Cost Buyers Money
Even experienced tea buyers make harvest-timing errors. The most common ones include:
- Confusing packaging date with picking date. A January packaging date does not make autumn or previous-year tea a spring product.
- Paying Mingqian prices for generic Biluochun. The Suzhou Dongting name is the protected part; Biluochun-style tea from elsewhere should trade at a different level.
- Buying too late without a storage plan. Green tea freshness is limited. Bulk spring tea should move into cold storage quickly and be released in controlled batches.
- Waiting for the absolute lowest price. Post-Guyu tea is cheaper, but if your customer expects classic Biluochun delicacy, it may not be the right product.
- Skipping harvest-date verification. Without a harvest date, you cannot tell Mingqian, Yuqian, or old stock apart.
The better approach is to treat the spring season as a short buying calendar: secure samples in late March, confirm grades before Qingming, and place volume orders when your target leaf standard is actually available.

Frequently Asked Questions
When is Biluochun picked?
The main Biluochun harvest starts in late March and runs through April, with exact dates shifting by weather. Pre-Qingming lots are the earliest and most tender, while post-Guyu lots are larger and more affordable.
Is pre-Qingming Biluochun always better?
It is usually more delicate and aromatic, but “better” depends on use. Mingqian is the top choice for high-end retail and gifting. For a stronger daily-drinking cup or a cost-conscious blend, Yuqian or post-Guyu tea may be more appropriate.
What is the cheapest time to buy Biluochun?
Prices normally decline after Guyu as larger-leaf spring tea reaches the market. The cheapest fresh spring tea is usually available from late April into May, but quality orientation shifts toward body rather than delicacy.
How long does fresh Biluochun stay at its best?
Green tea is best consumed within six to twelve months when stored cold and sealed against moisture, air, and light [3]. A spring lot held too long in ambient conditions will lose aroma and color.
Should importers buy immediately at harvest or wait?
Secure samples as soon as lots are finished, but only place large orders after tasting this year’s tea. The Qingming-to-Guyu window is often the practical balance between freshness, quality consistency, and price.
How can I tell spring Biluochun from old stock?
Check the harvest date, look for bright green color and fine white tips, and taste for lively floral or chestnut notes. Dull leaf, flat aroma, or fading color often signals older or poorly stored tea.
