Tips & Quirks

Things to know about dialing in the Zero.

ux

Popcorning: Early Niche Zero units suffered from beans bouncing back out of the burr chamber during grinding. Niche addressed this with the NFC (Niche Flow Control) disk accessory that attaches to the bottom of the hopper and slows bean feeding. Included with newer units.

recommendation

Oily dark roast beans may not feed by gravity through the single-dose hopper due to insufficient steepness. Users report needing to manually push remaining beans into the throat when grinding very dark or oily beans.

recommendation

Grind dial is sensitive in the espresso range: moving just 1/3 of a mark (e.g., 17 to 17.3) can shift shot time by ~5 seconds. Make very small adjustments when dialing in for espresso.

ux

Calibration numbers are not transferable between units. Settings reported online are only a rough starting guide. Each grinder must be individually dialed in regardless of what numbers others report.

positive

Very low retention (~0.4-0.7g) makes it excellent for single-dosing and switching between brew methods. Maximum exchange from previous grind is under 1.7% in an 18g basket.

recommendation

Static is low from new, especially compared to other grinders. A few drops of water (RDT — Ross Droplet Technique) on beans before grinding eliminates any remaining static.

Calibration

Unit-to-unit variance and zero-point info for the Zero.

Variance

±5 dial marks (0-50 numbered on collar)
Medium variance — calibration recommended

Zero Point

Burr-touch calibration: (1) Clean grinder thoroughly. (2) Screw on bean funnel hand-tight. (3) Rotate top dial clockwise until burrs touch and dial will not turn further. (4) Rotate the black bottom bezel ring until the silver indicator ball aligns with the 'Calibrate' mark. (5) Rotate bean funnel anticlockwise to desired grind setting. Factory ships grinders calibrated at setting 20 as a safety measure to prevent running at zero.

Calibration is arbitrary and depends on how firmly the user tightens the burrs at zero. A grown adult vs. a lighter-handed person can produce different calibration points. Variance of 5-7 marks between units is normal. Once calibrated, the setting is stable — use tape trick on bezel ring to mark position before cleaning to restore exact calibration afterward. Burr wear over time (rated ~1600 lbs of coffee) will cause gradual drift toward finer settings.
