Wu Niu Zao

An exceptionally early-budding Zhejiang cultivar, harvestable two to three weeks before Longjing 43. Much of the 'pre-Qingming Longjing' on sale early in the season is Wu Niu Zao, shaped in the Longjing style.

Where it sits in the botany

Wu Niu Zao is recorded under Camellia sinensis var. sinensis, the variety group one level above cultivar. It is associated with China, which is where it was selected or is most widely planted rather than the only place it grows.

Also transliterated as: wu niu zao, wuniuzao.

What the plant is like

Flatter in flavour than true Longjing cultivars and noticeably less nutty. Recognising it is the most practical defence against paying a first-harvest premium for the wrong plant.

Why a grower plants it

Yield, hardiness, when it buds, what it resists and whether a machine can cut it. This is the half of a cultivar’s identity that decides what is actually in the ground, and it is usually left out of writing aimed at drinkers.

Bred against the calendar and nothing else. It buds two to three weeks ahead of Longjing 43 in the same conditions, and in a market that pays a steep, fast-decaying premium for the earliest spring tea that head start is the entire commercial case. The exposure is the one every early cultivar carries and it is worse here in proportion to the advantage: the most valuable crop of the year sits in front of whatever late frost the season produces.

What it does in the cup

Reported as flatter and noticeably less nutty than the Longjing cultivars, which is the trade-off for the date. It is a competent early green tea rather than a distinguished one.

How much of this is really the cultivar?

Much of the pre-Qingming Longjing on sale at the very start of the season is this plant, shaped in the Longjing style, and being able to recognise it is the most practical defence a buyer has against paying a first-harvest premium for the wrong bush. Note the direction of the claim carefully: this is a statement about what is sold as Longjing, not a statement about what Longjing is made from.

Cultivar, growing site and processing all shape a cup, and the cultivar is very often the smallest of the three. It is also the one that fits on a label, so almost every commercial incentive runs toward overstating it. This section is on every cultivar page that has been reviewed for it, including the ones where the honest answer is “less than you would think”.

What it is usually made into

The categories this cultivar is typically processed into. It is a statement about common practice, not a limit — processing decides the category, and a cultivar can be taken down more than one route.

  • Green tea — Tea whose oxidation is halted early by heat, keeping the leaf green and the cup fresh, vegetal or marine in character.

Written comparisons

Where TeaHQ has set this cultivar against something it is routinely confused with, and argued the differences out in full.

  • Longjing 43 vs Wu Niu Zao — Much of the ‘pre-Qingming Longjing’ on sale early in the season is not made from a Longjing cultivar at all. Wu Niu Zao buds two to three weeks earlier and is shaped in the Longjing style, and recognising it is the most practical defence a buyer has.
