Inside the Hey Café Jack coffee grinder
German Steel Burrs
64mm hardened steel flat burrs, made in Germany, hold their edge for high grinding performance and a cleaner cup.
Cast Aluminium Chamber
Cooling ribs on the grinding chamber limit heat transfer to the coffee, protecting delicate aromatics during long runs.
Stepless Grind Range
An extra-wide, stepless dial lets you dial in espresso, pour-over, or French press without hunting between fixed clicks.
Low Retention Flow
A steady, low-retention path keeps ground coffee moving through, cutting waste and keeping every dose repeatable.
Quick-Clean Access
An integrated spout and flapper give fast access for daily cleaning, without tools or downtime.
Height-Adjustable Tray
The dosing tray adjusts in height to fit portafilters, cups, and containers of varying sizes.

Hey Café Jack Grinder — frequently asked
Is the Hey Café Jack Grinder suitable for a home bar?
Yes. Its low noise level and compact footprint make it workable on a home counter, while its stepless adjustment covers espresso through French press.
Can it handle single-dose grinding?
Yes. The included purge unit is designed for single-dose use in addition to the standard hopper-fed workflow.
How often should the burrs be cleaned?
Brush the burrs weekly to clear coffee residue, and check your grind settings periodically to keep results consistent.
Will it work for both espresso and filter brewing?
Yes. The extra-wide stepless range is built to move between espresso, pour-over, and French press grind sizes.
How is heat transfer to the grounds managed?
Friction inside the burr chamber generates heat. The cast aluminium chamber with cooling ribs limits how much of that heat reaches the ground coffee.
Who the Hey Café Jack Grinder is built for
This is a grinder for specialty coffee shops, roasteries, and home brewers who want café-grade consistency without guesswork — precise enough for competition-level espresso, simple enough for a daily home ritual.
