Key specs explained for this grinder
Burr Size: 48mm

You get efficient grinding for daily use without excessive effort. This dimension helps ensure uniform grounds for pour over or French press brewing, supporting a balanced extraction in your cup.
Grinding Mechanism: Conical burr
This grinder uses conical burrs, which are stacked in a cone shape. This design typically produces fewer fines than flat burrs, reducing bitterness.

This mechanism is a standard choice for manual grinders seeking consistency and ease of use.
Grind Settings: 30 clicks per rotation
The adjustment dial offers 30 distinct clicks for each full turn. This provides precise control over your grind size. You can dial in specific settings for different brewing methods, from coarse for French press to fine for espresso. The numbered internal adjustment helps you remember your preferred settings. This level of granularity allows for consistent results across multiple brewing sessions.
Burr Material: Stainless steel
The burrs are made from stainless steel, known for durability and resistance to corrosion. This material maintains sharpness over time, ensuring consistent grind quality.
