Over-extracted. The water's pulling too much out of grounds that are too fine.
Coarsen the grind one step, and stop the brew a touch sooner.
Not a course. Not a timer. Tell it what's on your counter and what's wrong with the taste, and it tells you the single thing to change.
Most advice assumes you'll buy more or watch more. Kafera assumes the opposite: you already own something that makes coffee, and you want it to taste good tonight.
So it starts from your kitchen, not a barista's. Free fixes before paid ones. Always.

Kafera builds your starting recipe around one of these. No new machine required.
Six taps. Your machine, your grinder, how you drink it, what's going wrong.
One setup, one method, one starting recipe built around your numbers. Not a list, just the one to start with.
Bitter today, sour tomorrow? Change one thing at a time, and always try the free fix before the paid one.
