J-Ultra
Grind settings, every brew method
Worked out from this grinder’s own dial curve — five reference points placed on a shared 0–100 grind index, interpolated with a monotone spline for conical burrs — rather than a one-size-fits-all chart.

The J-Ultra widens the useful band relative to the J-Max, trading a little espresso resolution for genuinely usable filter and French press. If you want one hand grinder for everything, this is the one in the range that tries hardest.
