① 2026–2027 Harvest Calendar at a Glance
| Month | Harvest Stage | Brix (Sugar) | Availability |
|---|---|---|---|
| Mid–late Oct | Early harvest (early varieties) | 10–12° | Limited (only 5–10% of output) |

*The Ganzhou government sets an official main-harvest start date each year. For 2026, the expected start is November 1, pending official announcement.

② How the Official Harvest Date Is Set
Unlike most regions where farmers harvest individually, Gannan operates under a unified harvest start date regulated by the Ganzhou Municipal Bureau of Agriculture and Rural Affairs. This system exists to:
- Prevent premature harvesting that damages the brand's reputation
- Guarantee minimum quality standards across all commercial fruit
- Coordinate marketing and export promotion
- Protect the Gannan GI (Geographical Indication) brand value
The date is set by fruit maturity sampling: harvest may begin once average Brix reaches 11–12°. Early-maturing varieties may be approved 1–2 weeks earlier.
③ Month-by-Month: What to Expect
October — Early Season (Limited Supply)
Early-maturing varieties like the "Gannan Early Navel" begin ripening in mid-to-late October — only 5–10% of annual output. Brix runs 10–12° with noticeable acidity. Good for channels that need first-to-market positioning.
November — Main Harvest Starts (Supply Ramps)
From November 1, Brix rises to 12°+ and all grades become available. This is the month to lock in your annual volume.
December — Quality Peak (Best Window)
Brix reaches 13–17° with the optimal sugar-acid ratio. Importers chasing top quality should target December sailings — ideal for the Christmas and Chinese New Year retail season in Europe.
January — Late Season (Premium Only)
Brix peaks at 14–17°, but supply tightens and prices hold firm. Suited to top-up orders and premium channels.
February — Final Harvest (Scarce)
Only a few late-maturing fruits remain; Brix eases to 12–15°. Extremely limited availability.
④ When to Buy: Timing Strategy
| When | Advantage | Best For |
|---|---|---|
| Aug–Sep pre-season contract | Locks price; 10–15% discount | Importers who plan ahead |
| October early harvest | First to market; grabs shelf space | Channels needing earliest arrival |
| Nov–Dec spot market | Best Brix + widest grade choice | Most wholesale/retail importers |
| Jan–Feb top-ups | Peak sugar; scarcity premium | Premium & specialty retail |
