Description
TEA & BEVERAGE INGREDIENT
Dark Tea Powder
Dark tea powder is a milled preparation of post-fermented tea leaf, supplied as a fine brown powder. It is a whole-leaf powder rather than a soluble instant preparation, so it retains the insoluble fraction and delivers body and colour rather than dissolving clear. The purchasing definition is the particle size, the moisture and the delivered colour and aroma.

Buyer Decision Guide
Agree the particle size, the moisture limit and the delivered colour before approval, since particle size drives both mouthfeel and the suspension behaviour in the buyer’s line. Confirm whether the application requires a soluble preparation, in which case an instant tea powder is the correct grade rather than this milled powder.
- Particle size and moisture 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
Dark tea is offered as milled leaf powder and as a soluble instant powder. The milled powder carries the whole leaf, including the insoluble fraction, and does not dissolve clear; the instant powder dissolves directly and delivers only the soluble fraction. Confirm which behaviour your application needs before comparing quotations.
For a substitution review, compare botanical identity, plant part, assay target, analytical method, physical form and the current offered-batch COA.
