These are starting points. Taste, then adjust one thing at a time: grind first, then ratio.

Taste and adjust. Sour: grind finer (a bigger ratio also extracts more). Bitter or dry: grind coarser. Too weak: smaller ratio (more coffee). Too strong: bigger ratio (more water). Change one thing per brew.
