Particle measurement basics
How to measure and understand grind particle size, distribution, and its impact on extraction.
Key concepts
Motor torque and speed
How the grinder motor's torque and rotational speed affect grinding performance, consistency, and heat generation.
Stepped vs stepless adjustment
The differences between stepped and stepless grind adjustments and how they affect dialing in espresso or other brewing methods.
Burr wear and replacement
How burr wear affects grind consistency and flavor, and when to replace them for optimal performance.
Heat generation and throughput
How grinder speed, burr type, and throughput influence heat buildup and coffee quality.
Static, clumping, and RDT
How static and clumping affect grind consistency and how the Ross Droplet Technique (RDT) can mitigate these issues.
