Phú Thọ
The province north-west of Hanoi where Vietnamese tea science lives. The French established a research station at Phú Hộ in 1918, and it has remained the country’s principal tea institute through every subsequent change of government — the source of the clonal selections planted across the northern midlands and much of the agronomy the industry runs on. The province itself carries a large planted area of that clonal material, worked for commodity green and black tea rather than for the ancient-tree speciality trade further north, and it is the ordinary face of Vietnamese production.
History on this page: TeaHQ synthesis
TeaHQ's own reading of well-attested general knowledge, with no single source behind it.
This district’s description dates something — a founding, a first planting, a period of expansion. The label above says on what basis, and it applies to the historical statements rather than to the elevation, climate or soil claims below, which carry their own confidence separately.
Elevation
Recorded at 30–400 metres.
How firm this is: Inferred from general knowledge of the district rather than measured or taken from a source that states it.
When it is picked
A long northern Vietnamese season with a cool winter slowdown rather than a hard dormancy: plucking runs from spring through autumn on a short cycle, with the spring crop the best of it and the rain-season growth fast, thin and destined for commodity manufacture. Clonal planting flushes evenly, so the rounds are regular in a way the old seed-grown stands further north are not.

How production is organised
Large planted areas of research-station clonal material worked for commodity green and black tea, alongside the institute that bred it. This is the ordinary face of Vietnamese production and the opposite of the ancient-tree trade the country is known for abroad: uniform plants, regular rounds, volume manufacture and no provenance story to sell.

How the name is written
Also transliterated as phu tho, phu ho. Romanisations of a district name vary by system and by vendor, and a packet spelling one way is not describing a different place.
Teas this region is known for
- Vietnamese green tea — Assertive and drying in a way most East Asian greens are not, with a sweetness that arrives after rather than during. The bitterness is culturally valued here rather than tolerated.
Other growing regions in Vietnam
The neighbouring districts are the useful comparison: they share a country, a grading convention and often a cultivar, so what differs between them is closer to terroir than anything a cross-border comparison can isolate.
