Is zedoary turmeric oil supply affected by seasonality?
Yes, like most rhizome oils, zedoary turmeric oil has a seasonal supply pattern. Curcuma rhizomes are harvested once a year (typically autumn to early winter in Guangxi and Zhejiang), and the freshly distilled oil is released in the months after harvest. Stocks remain available year-round, but specific Dao-di lots are limited.
Seasonal Pattern
| Period | Supply situation |
|---|---|
| Harvest season (Oct-Dec) | Fresh rhizomes available; new oil released |
| Post-harvest (Jan-Apr) | New oil in stock, best freshness and markers |
| Mid-year (May-Sep) | Old stocks; quality stable, availability depends on volume |
| Dao-di Wen-ezhu lot | Limited annual output; reserve early |
How We Manage It
- Annual production planning with farmers and cooperatives in Guangxi and Zhejiang
- Cold storage of rhizomes extends the distillation window
- Buffer stocks of finished oil (both pharmacopoeia and fragrance grade) maintained for year-round supply
- Standing customers get priority allocation of new-harvest lots and fixed pricing
Buying Advice
- If you need Dao-di Wenzhou Wen-ezhu pharmacopoeia grade, place your order before the harvest (Q3) to reserve the lot
- For regular fragrance-grade supply, standard stocks cover most orders without seasonal impact
- Lock annual volume at the beginning of the year to stabilise price and guarantee allocation
