Pressing vs grinding
Grinding turns nibs into a fluid mass. Pressing splits that mass into cocoa butter and cocoa cake. Everything downstream forks here.
Side by side
| Pressing | Grinding | Why it matters | |
|---|---|---|---|
| What comes out | Two streams: cocoa butter, and a solid cake milled into cocoa powder. | One stream: cocoa mass, containing everything the nib had. | This is the fork in the whole industry. Chocolate making takes the grinding path; the cocoa powder trade takes the pressing path. |
| Order | Always after grinding — you cannot press a solid nib effectively. | First. | |
| Fat control | Adjustable. Press duration and pressure set the residual fat, which is how 10–12% and 20–24% powders are made. | None. The mass keeps the bean's natural ~55%. | The fat percentage on a tin of cocoa is a press setting, and it is the main quality variable between powders. |
| Economics | Cocoa butter is typically worth considerably more per tonne than cocoa powder, so the ratio between the two markets drives grinder behaviour. | Not applicable — nothing is separated. |
Choose Pressing when
When the product is cocoa powder, cocoa butter, or any chocolate needing added butter beyond what the bean carries.
Choose Grinding when
When the product is chocolate, where the bean's own fat stays where it is.
