What's the best manual coffee grinder for espresso, for pour-over, or under $100? Six hand grinders, and the one idea each teaches you about what actually matters in a grinder.

A grinder is a gap between two burrs. How firmly it's held, how finely you can set it, and what the burr does inside it shape the spread of particle sizes, and that spread shapes your cup. We walk through six grinders, one idea at a time, then put all six and five lower-price alternatives on a map by budget and brewing method.

A NOTE ON THE DIAGRAMS
The grinder cutaway, the size charts, the wobble and the espresso window are schematic illustrations, not measurements of any grinder in this video. The step sizes on the click ladder are the makers' stated adjustment per click, not the size of the grounds.
