Long before a dried bird's nest reaches a box, it crosses a sorting bench, where a trained worker holds it under strong light and places it into one of several quality tiers by hand. There is no machine or barcode scanner that makes this call — a person does, piece by piece, based on cup shape, size, colour, and intactness.
Key Takeaways
- Sorting is done entirely by hand under strong light, one piece at a time.
- Sorters judge each nest by cup shape, size, colour, and intactness — not cleanliness alone.
- Ten Lei Yen's own tiers are S grade (Blue Label Supreme + Red Label Super) and A grade (everything else, including 5A).
- A skilled sorter can take years to learn to judge a nest correctly at a glance.
- Pieces that don't make the top tier aren't wasted — many become broken nest.
What Happens on the Sorting Bench?
The Light Table
Sorting happens over a small illuminated table, similar to the light boxes photographers use to check film. Held up to that light, a dried nest reveals things a naked eye in normal room light would miss: thickness, evenness, hairline cracks, and any thinning or gaps in the weave. A sorter tilts each piece under the light, turning it over, before deciding where it belongs.
What Sorters Look For
Four things matter most on the bench:
- Cup shape — is the piece a clean, intact half-cup or boat, or is it cracked, flattened, or fragmented?
- Size — larger, fuller cups sort differently than small or thin ones.
- Colour — is the tone even, or blotchy and unevenly stained?
- Intactness — is the piece whole, or are strands broken and loose?
| What Sorters Check | Passes to the Top Tier | Downgraded |
|---|---|---|
| Cup shape | Intact half-cup or boat, clean edges | Cracked, flattened, or fragmented |
| Size | Larger, fuller cups | Small or thin cups |
| Colour | Even ivory-white or natural gold tone | Blotchy or unevenly stained |
| Intactness | Whole piece | Broken strands or loose fragments |
Who Does This Work?
Sorting is handled by experienced workers, often the same people who oversee cleaning, who have spent years learning what a nest of each tier looks and feels like. It isn't a job that can be picked up in an afternoon: judging a nest correctly at a glance, without needing to hold every piece up to the light for minutes at a time, takes real repetition.
Why Sorting Takes So Long
Every nest is a natural, irregular object — no two are identical, so no simple measurement (weight or size alone) can sort them accurately. A sorter has to weigh shape, colour, and intactness together for each individual piece, which is why a batch of nest can take hours to sort properly, long after cleaning is already finished.
What Gets Downgraded?
A nest doesn't get discarded just because it misses the top tier. Cracked cups, uneven colour, or strands that came loose during cleaning are common reasons a piece moves down a tier. Many of these downgraded pieces are still entirely usable — they're simply sorted into broken nest or a lower grade box instead of a premium whole-cup box.
From Bench to Box
Once sorted, nests are grouped into Ten Lei Yen's two working tiers: S grade, covering Blue Label Supreme and Red Label Super, and A grade, covering everything else in inventory, including 5A. The sorting bench is what actually creates that split — grading isn't decided at checkout, it's decided by hand, tray by tray, long before a box is ever sealed.
Frequently Asked Questions
Is bird's nest sorting done by machine?
No. Sorting is done entirely by hand under strong light. A trained worker examines each piece individually and places it into a quality tier — there is no automated scanner involved.
What is the difference between S grade and A grade at Ten Lei Yen?
S grade covers Blue Label Supreme and Red Label Super. A grade covers everything else in inventory, including 5A.
What happens to nests that don't make the top tier?
They aren't discarded. Many are sorted into broken nest or a different grade, since the underlying material is still genuine, usable bird's nest.
How long does it take to become a skilled sorter?
There's no fixed timeline, but sorters typically build their judgment over years of handling nest daily, since shape, colour, and intactness all have to be weighed together for every single piece.
