Description
TEA & BEVERAGE INGREDIENT
Oolong Tea Powder
Oolong tea powder is a milled preparation of semi-fermented tea leaf, supplied as a fine powder. The degree of fermentation is part of the identity of this grade and drives the balance of colour and aroma between green and fully fermented tea. The purchasing definition is the particle size, the moisture and the delivered organoleptic profile.

Buyer Decision Guide
Agree the degree of fermentation, the particle size and the moisture limit before approval, and confirm whether the application needs a soluble preparation instead. Where the finished product is colour-sensitive, approve against a retained sample rather than on the specification sheet alone.
- Degree of fermentation and particle size stated on the certificate of analysis
- Confirmed as a milled leaf powder, not a soluble instant preparation
- Delivered colour and aroma agreed against a retained sample
- Packing and particle size agreed at quotation
- COA, specification sheet and safety data sheet accompany each shipment
- Regulatory status, permitted uses and labelling are the buyer’s responsibility for the destination market
How This Grade Differs
Oolong is offered at different degrees of fermentation, as milled leaf powder and as a soluble instant preparation. The fermentation level and the delivered form both change the colour and aroma contribution, so a substitution should be evaluated in the buyer’s own application.
For a substitution review, compare botanical identity, plant part, assay target, analytical method, physical form and the current offered-batch COA.
