What you are aiming for

Flat-bottom drip baskets like a medium grind, close to coarse sand. Use the ratio, not the scoop marks on the carafe.

On the 1Zpresso K-Ultra, 6.0 is the documented start. If your grounds look much finer or coarser than this, your grinder may be calibrated differently: trust the taste, then the number.

Fix the beans too

Better drip machine starts with fresher beans.

The right grind only gets out what the beans have. A subscription keeps fresh coffee arriving before you run out.
