Sun-dried vs machine-dried pu-erh
The step that decides whether a pu-erh cake can age at all, and the one a buyer cannot see. It is the most consequential invisible difference in the category.

What is being compared
Why these get confused
'Sun-dried' is often assumed to be a marketing flourish. It is the mechanism the whole category depends on.
Point by point
| Aspect | Sheng maocha | Sheng dragon ball |
|---|---|---|
| Drying | Sun-dried at low temperature, leaving enzymes and microorganisms active. | Also sun-dried here — the contrast is with machine finishing, which is common in wet weather. |
| Why it matters | Residual activity is what decades of storage act on. Without it the tea simply goes stale. | Same material, so the same applies; format is the variable in this pair. |
| What a buyer can check | Very little. It is not visible in the leaf and wrappers rarely state it. | Equally little. |
| Effect on ageing | Full ageing potential. | Full potential from the material, reduced by the format: small balls expose far more surface than a cake. |
| Practical advice | Buy from sellers who state their drying method, and read silence as a question rather than an answer. | Drink these rather than store them. |
The short answer
Sun-drying is functional, not romantic. A cake made from machine-finished maocha will not age the way a sun-dried one does, whatever the wrapper claims.
