Tea professional
Evaluation, grading, sourcing and blending: the working knowledge of the trade.
Professional
1. Evaluation
Everything else in the trade rests on repeatable assessment.
2. Grading and quality
Grade and quality are different questions, and buyers are paid to know it.
3. Sourcing
How tea changes hands decides what a buyer can know about it.
4. Blending and scenting
Consistency is a product too, and it has its own economics.
5. Claims and protection
Regulation decides which claims on a label are enforceable.
