Grinders
Kinu
Kinu is a German maker of precision hand-cranked coffee grinders built around 47mm professional-grade conical burrs, auto-centered and running on ball bearings for fast, consistent grinding. It's known for a stepless adjustment system that dials in grind size in increments as fine as a few microns, and for over-engineered all-metal builds backed by a 5-year warranty. Its grinders span espresso to filter, prized for repeatable extraction across the whole range.
