Single dosing means weighing beans in and getting the same weight out, with nothing stale left behind. These four minimize retention through straight-through grind paths, bellows or knockers, and low-static designs.

Questions, answered
What does single-dose actually mean?
You weigh the exact beans for one brew, grind them all, and nothing stays in the grinder. No stale grounds sit in a hopper or chute between sessions, so every cup starts from fresh beans.
Is single dosing worth the extra effort?
If you brew one or two cups and switch beans or methods often, yes: retention of a gram or two in a hopper grinder is a meaningful share of an 18 g dose. For large daily batches, a hopper grinder with timed dosing is more practical.
Do I need a scale for single dosing?
Yes, a 0.1 g scale is part of the workflow. You weigh beans in and can verify grounds out, which is how you confirm your grinder's retention is actually low.
Which single-dose grinder is best for espresso?
The 1Zpresso JX-Pro and KINGrinder K6, with 12.5 and 16 micron click steps respectively. The Ode Gen 2 is filter-only. Our best espresso grinders ranking covers electric espresso options.
