Retention and single-dosing
How grinder retention affects freshness and consistency, and the principles behind single-dosing strategies.
Key concepts
Grind distribution and fines
How the particle size distribution, particularly fines, affects extraction uniformity and flavor.
Alignment and parallelism
How precise alignment and parallel positioning of burrs affects grind consistency and extraction performance.
Burr geometry and cutting angles
How the shape and angles of burrs influence grind efficiency, particle size distribution, and flavor extraction.
Burr types: flat vs conical
The differences between flat and conical burr grinders and their impact on grind consistency.
Customer communication on defects
