Leaf separation by hand (ban pian)

The categories this step defines

In tea, processing is not a modifier applied to a category — it is what creates the category. These are the types that exist because this step exists.

• Green tea — Kill-green (fixation) applied before meaningful oxidation can develop.

What it is

The second operation in Liu An Gua Pian and the one that decides everything after it. A picked shoot arrives as a bud with leaves attached; a worker snaps it apart between finger and thumb, and only the leaf blades continue. The bud is removed — which inverts the usual Chinese hierarchy, where the bud is the expensive part — and so is the stem, and the leaves are separated into first and second so that pieces of similar thickness are fired together. It is slow, it is done on fresh leaf before any heat, and there is no machine for it. What it produces is a batch of single leaves of even substance, and that evenness is the precondition for the rest of the route: leaves with no bud and no stem can take the very high final charcoal heat without breaking up, which is why this tea can be fired the way it is and an ordinary green tea cannot.

Also transliterated as: ban pian, banpian.

What it does to the leaf

Separates leaf blades from the bud and the stem of each fresh shoot by hand, and sorts them by position, producing a batch of uniform single leaves before any heat is applied.

What it does to the cup

Removing the bud removes most of the downy sweetness a Chinese green is usually bought for, and removing the stem removes a source of moisture that would otherwise steam the leaf in the pan. The result is a cup with less bud-derived sweetness and far more toasted depth, which is the trade the whole tea is built around.

Variants that matter

Ways this step is carried out that produce genuinely different results, rather than regional names for the same thing.

First and second leaf kept apart

The two positions are fired as separate batches because they differ in thickness and would not dry at the same rate together. In the finished tea they are graded and sold separately.

Other steps at the Plucking stage

• Fresh-leaf reception and grading — The decision, taken at the factory door, about which intake becomes which product — and the point at which a day's leaf is split into separate lots that never meet again.
• Fresh-leaf transport and holding — The hours between the bush and the factory door, during which a packed bag of leaf can heat itself and start changing before anybody has decided what it should become.
• Hand plucking — Picking each shoot individually by hand, which is the only method that can choose what to take and what to leave.
• Mechanical harvesting — Cutting the top of the plucking table with a powered blade, which takes everything at a set height regardless of what is ready.
• Plucking standard — The rule about how much of each shoot is taken — bud only, bud and one leaf, bud and two, or mature leaf — which is set before any factory decision is made.
• Shading — Covering the bushes for days or weeks before plucking, which changes the leaf’s composition before it is ever picked.
