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.
What it is
A factory taking leaf from more than one field, more than one picker or more than one time of day does not process it as one mass. Reception is where somebody looks at each delivery, judges its standard, its condition and its temperature, weighs it, and directs it to a bed — fine early leaf to the line making the top grade, coarser or later leaf elsewhere, damaged or heated leaf to the route that can absorb it. The consequence people notice is the reverse one: where reception is not done, everything is tipped together, and the finished tea contains material that was over-withered and material that was barely withered because they entered the same trough at different states. It is also the last moment at which the intake can be described honestly. Once a lot is combined, no downstream record can recover which garden or which round it came from, which is why traceability schemes and geographical indications place their requirements here rather than further along.
Also transliterated as: xian ye yan shou, xianye yanshou.
What it does to the leaf
Assesses, weighs and segregates arriving leaf by plucking standard, condition and temperature, and assigns each lot to a processing route before any operation is performed on it.
What it does to the cup
Sets the uniformity ceiling for the batch: a segregated intake can be processed to one endpoint, while a mixed one produces a cup containing both under- and over-processed material regardless of how well each step is run.
Variants that matter
Ways this step is carried out that produce genuinely different results, rather than regional names for the same thing.
- Payment by grade
- Where pickers are paid on assessed standard rather than weight alone, reception becomes a commercial negotiation as well as a technical one, and the assessment has to be visible and consistent.
- Cooperative receiving stations
- Common in Japan, Kenya and Taiwan. Many growers deliver to one facility, which makes segregation harder and consistency across a season easier.
- Single-estate intake
- One garden, one factory, one schedule. Reception collapses into the plucking round itself, which is why estate teas can be described by flush and smallholder blends usually cannot.
Where this gets misdescribed
Traceability is read as a paperwork exercise bolted onto a finished tea. Whether a lot can be traced is decided physically, at reception, by whether it was kept separate — and no certificate issued later can un-mix a bed of leaf.
Other steps at the Plucking stage
- 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.
- Leaf separation by hand (ban pian) — Breaking each freshly picked shoot apart by hand so that the individual leaves go forward and the bud and the stem are set aside.
- 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.
