Buying Guide: Grinders
A good grinder matters as much as the machine — arguably more. It sets the particle size and consistency that every other variable depends on, so if your budget is split, don't starve the grinder. Read grinder burrs for the theory behind these picks.
Match the grinder to your needs
- Budget, travel, or no power → Hand Grinder ($89). Manual 38mm conical, stepless, single-dose. Expect ~30-45s of cranking per dose. Compact and quiet.
- Best-value electric, forgiving, works with any machine → Compact ($219). Electric 40mm conical, 40 stepped settings, 150g hopper. The cheapest electric and the easiest to live with; the sweet spot can occasionally fall between two steps.
- Flat-burr clarity plus single-dosing at mid price → Vortex ($349). Electric 64mm flat, stepless, near-zero retention. A cleaner, more articulate cup than conical.
- Flagship clarity and finest adjustment → Precision ($429). Electric 83mm flat, stepless high-resolution, single-dose. Maximum clarity — and the least forgiving, so it rewards good technique.

| Precision | 83mm flat | Stepless | $429 | Flagship clarity, finest control |
Pairing advice
- Pair flat-burr grinders with temp-stable machines. The clarity of the Vortex or Precision exposes every inconsistency, so they shine on a PID single boiler or dual boiler where brew temperature is steady.
- Conical grinders are more forgiving and a natural match for a first setup or milk-focused drinks.
- Stepless adjustment helps most on espresso, especially with flat burrs where small moves matter.
Check compatibility for basket and dosing-cup fit, then work through dialing in for each new coffee.
