Cai Cha

The seed-grown mixed population that predates named cultivars in Fujian, and the original stock for both Gong Mei white tea and traditional Zheng Shan Xiao Zhong. Because it is a population rather than a clone, no two gardens are quite alike.

Where it sits in the botany

Cai Cha 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: cai cha, caicha.

What the plant is like

Its variability is the reason older Fujian teas taste less uniform than modern ones, and is a genuine quality in categories where complexity is wanted.

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.

Small-leaved, seed-grown, uneven and low-yielding — the stock the Da Bai cultivars were selected to replace, and largely did. Where it survives it is usually on marginal ground, in old plots nobody replanted, or kept deliberately by producers making Gong Mei and Shou Mei, whose grades want a leaf rather than a bud and therefore lose nothing by using it. Its buds are small and thinly downy, which rules it out of the Silver Needle grades entirely.

What it does in the cup

Less sweet and less downy than Da Bai material, with more herbal and wild-flower notes and a firmer, drier edge. In traditional smoke-dried Zheng Shan Xiao Zhong it gives a leaner, more resinous base than a modern clonal leaf would.

How much of this is really the cultivar?

Cai Cha is worth a record chiefly because it makes the grade system legible. The difference between Bai Hao Yin Zhen, Bai Mu Dan and Shou Mei is a plucking standard — all bud, bud plus leaves, mostly leaf — and it interacts with cultivar rather than being independent of it: Da Bai for the bud grades, Cai Cha content perfectly acceptable in the leaf grades. So a Shou Mei tasting rougher than a Silver Needle is being caused by picking standard, cultivar and price point simultaneously, and attributing it to any one of the three is a mistake.

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.

White tea — The least handled category: withered and dried, with no fixation and no deliberate rolling.
Black tea — Tea taken deliberately through full enzymatic oxidation, giving the dark leaf, amber-to-red liquor and malty or brisk character most Western drinkers think of as simply 'tea'.

Guides covering this cultivar

Landrace populations and clonal monoculture — A field of one clone and a field of a seed-grown population are two different agricultural objects. The difference runs all the way through — when the field is picked, how the factory has to work, what the cup does, and what happens in a bad year.

Written comparisons

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

Cai Cha vs Fuding Da Bai — The seed-grown population that predates named cultivars in Fujian, and the selected cultivar that displaced it for white tea. The difference explains why Silver Needle looks the way it does and why older Fujian teas taste less uniform than modern ones.
Qun Ti Zhong vs Cai Cha — The two seed-grown populations that predate named cultivars in Zhejiang and Fujian respectively. Neither is a cultivar in the strict sense, and both are valued for the one property clonal planting removes: variability.
