Opus
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.

Marketed as all-purpose, and it genuinely does cover more range than the Ode, but the espresso end is workable rather than good — expect to chase it. Where it earns its place is the coarse end: cold brew and French press come out notably even. If you bought the Opus mainly for espresso, dial it as a brew grinder first and judge it there.
