Burr types: flat vs conical

Key Concepts

• Flat Burrs:

• Burrs are parallel to each other, creating a uniform grinding path.

• Typically provide very consistent particle size.

• Often produce more heat due to higher rotational speeds.

• Conical Burrs:

• Burrs are cone-shaped; coffee is crushed and sheared between inner and outer burrs.

• Tend to generate less heat, preserving aroma.

• Can handle larger bean volumes and are quieter in operation.

• Grind Consistency and Particle Distribution:

• Flat burrs often yield slightly narrower particle distribution.

• Conical burrs may produce a small fraction of fines but are gentler on beans.

• Maintenance Considerations:

• Flat burrs may require more precise calibration and cleaning.

• Conical burrs are typically easier to maintain but may be larger.

• Choosing Based on Brew Method:

• Espresso: both types work well; flat burrs often favored for precision.

• Filter: conical burrs are often preferred for preserving subtle flavors.

Summary

Flat and conical burr grinders each have trade-offs in heat generation, particle consistency, and maintenance. Selection should align with brewing method, desired flavor preservation, and grinder usage patterns.
