How the tribute system worked
TeaHQ's own reading of well-attested general knowledge, with no single source behind it.
Designated gardens were required to supply tea to the court, with quantities, timing and quality specified. Tribute status conferred prestige on a region and imposed real burdens on the growers responsible for meeting it. The system operated across several dynasties with substantially different arrangements in each, and this is a compiled general account of the shape of it rather than a summary of any particular dynasty's regulations, none of which TeaHQ has read.
Its effect on how teas are ranked today
TeaHQ's own reading of well-attested general knowledge, with no single source behind it.
A number of teas still marketed as historically significant trace their reputation to tribute status, and 'tribute grade' persists as a commercial term with no defined modern meaning. The famous-tea lists that organise Chinese tea marketing draw substantially on this inheritance.
