- Coated burr designed for espresso
- Magnetic catch cup holds 35–40 g of grounds

Overview
A good hand grinder is the cheapest way to get espresso-quality grinding, and the J-Ultra is built specifically for it. Each click of the external dial moves the burr by just 8 microns, which gives you the fine control espresso needs, and the burr is factory-calibrated to stay stable over years of use.
The catch is effort: you grind every shot by hand. For one or two drinks a day that is part of the ritual; for a busy household an electric grinder like the Encore ESP is easier.
Pairs well with the Bambino Plus, a scale for weighing beans, and single-dose bean tubes so each shot's beans are ready to go.
