For espresso grinding, a manual grinder needs fine adjustment steps to easily dial in the perfect grind for each coffee bean. The S3’s 15-micron micro-adjustment satisfies this requirement perfectly.
Beyond this essential feature, the S3 ESP offers two additional advantages:
- Smoother grinding experience: The 8 burr blades distribute coffee evenly, with limited capacity allowing you to grind small portions effortlessly.
- Optimized particle distribution for richer espresso: Compared to the standard S3 with S2C890 burrs, the S3 ESP uses conical S2C-042-EI burrs that increase fine particle ratio to enhance coffee body. This small percentage increase in fines creates a noticeable difference in richness while preserving the essential aromatics.

There’s a significant difference in burr blade count between the Timemore S3 ESP and S3. The S2C-042-EI has 8 blades while the S2C890 has 6 blades.
