NAVERQIO Grinders — where the cup is decided

Single-dosing is honesty in grinder form. The Ravello makes it effortless — near-zero retention, alignment that survives the courier, and burr options that turn a home bar into a small laboratory with crema.

Burrs are the whole argument. Ours are cut from hardened tool steel or coated in titanium nitride, measured on an optical comparator, and matched in pairs; carriers are machined, not cast, so alignment survives shipping, seasons and years of shots. Chirp-free at zero, even after the ten-thousandth kilogram.

Design & Craft

  • Stepless micro-adjustment travels espresso to filter and back
  • Small footprint, full-size grind quality — a home bar's quiet flagship
  • Titanium-nitride burr option doubles service life
  • Motor wound for torque without heat; sealed oversized bearings
  • Machined burr carriers hold alignment through shipping and seasons
  • Burr pairs matched on an optical comparator and shimmed to zero chirp

Care

Brush the burr chamber weekly and run grinder cleaning pellets monthly; never wash burrs in water. Check alignment and burr wear at the annual service — we track burr life by kilograms and remind you before the cup does.

Questions, Answered

How loud is it?
Measured sound levels are in the specification — our shop grinders run in the low 70s dB(A) under load, single-dosers quieter still. If the grinder is the loudest thing on your bar, something else is very right.

How long do burrs last?
Tool-steel burrs are rated in the specification (typically 800–1500 kg for shop sets); titanium-nitride coatings extend that two- to three-fold. Replacements are stocked for fifteen years and change in minutes.

The NAVERQIO Promise

One standard across the range: if we would not put it on our own bar in Prague, it does not ship with the NAVERQIO mark.
