The serving is the practice
A description of something people do now, compiled from published accounts rather than from practice.
Tea is poured from a considerable height into small glasses. This aerates it, cools it to drinking temperature and raises the foam that a well-made glass is judged by. Serving is commonly the responsibility of a particular person, and offering tea to a guest carries obligation on both sides.
Three rounds
A description of something people do now, compiled from published accounts rather than from practice.
Three successive servings from the same leaf are conventional, each described as differing in character from the last. A saying comparing the three to life, love and death is very widely quoted in outside writing; it is a real saying and it is not a rule governing practice, and TeaHQ records it as one rather than the other.
Chinese leaf, North African practice
TeaHQ's own reading of well-attested general knowledge, with no single source behind it.
The base is imported Chinese gunpowder green tea, and the trade relationship that established it is long-standing. The preparation is entirely North African; the leaf is not. Describing the drink as a Chinese green tea would misplace it, and describing the leaf as local would be wrong.
