Withering vs drying
Both steps remove water from the leaf and they sit at opposite ends of the process for opposite reasons. Withering removes enough moisture to make the leaf workable and to let its chemistry start moving; drying removes enough to make sure nothing moves at all.

What is being compared
Point by point
| Aspect | Withering | Drying |
|---|---|---|
| Where in the sequence | First, on freshly plucked leaf. | Last. Every category ends here. |
| Purpose | Soften the leaf for handling and permit early aromatic development. | Reduce moisture far enough that enzymatic, microbial and oxidative change effectively stops. |
| Moisture removed | Partial. The leaf stays flexible and alive. | Down to a level at which the tea is stable enough to pack and store. |
| Temperature | Ambient or gently warmed, indoors or in sun. | Hot air, sun or a basket over heat, depending on tradition. |
| Flavour contribution | Substantial and deliberate — this is where floral and honeyed character develops. | Method-dependent: sun drying leaves a dry-hay note, basket firing a light toast, hot air very little. |
| Consequence of doing it badly | A rushed wither gives a flat tea with nothing built into it. | Under-drying is the commonest defect in home-stored tea — the leaf goes stale and musty rather than ageing gracefully. |
| For dark tea specifically | Sun withering is traditional for white tea and some sheng maocha. | The decision that determines whether the tea can age at all: dried too hot and too hard, it is stable but inert. |
The short answer
Drying is treated as a mechanical afterthought and it is the step that decides a cake’s entire future. Withering is treated as waiting around and it is where a white tea’s character is actually made.
