A machine to make your own.
Freshly ground. Every morning.
Small tools. Better mornings.
The 1Zpresso J-Ultra Coffee Grinder is a premium manual grinder built for the fine adjustments and consistency demanded by espresso. Its coated burr set is paired with an external adjustment system offering just 8 microns between clicks, giving you the control to make small changes to shot time without jumping past the setting you need.
Made to Dial In
The external adjustment ring keeps grind changes quick and easy, with 100 clicks per rotation and clearly marked settings you can return to as your coffee changes. Each click moves the burr by just 8 microns, giving espresso drinkers the fine control needed to work with different beans, doses and recipes without opening the grinder to make adjustments.
Built Around Espresso
A coated stainless steel burr is optimised for fine to ultra-fine grinding, with 1Zpresso tuning the J-Ultra towards sweetness and precision in espresso. The large burr and comfortable rounded body also make grinding fine coffee easier by hand, while the foldable handle packs neatly against the grinder when you're finished.
Simple From Dose to Cleanup
A magnetic catch cup holds approximately 35 - 40g of ground coffee and twists away from the grinder for easy transfer into your portafilter. When it's time to clean, the J-Ultra can be dismantled without tools, with a cleaning brush and blower included to clear retained grounds without disrupting your grind setting.
