You're getting a "baseline" with French press, which is convenient for people who don't want to fuck with a lot of brewing variables, but along with a brew method you can't fuck up you get lower extraction. Immersion methods use coffee to brew coffee, after all.

Not at all surprising that the method where you're constantly adding fresh solvent to the grounds is going to be less tolerant of sub-optimal grind sizes. Thanks, Jimmy.
