Timer

What it is and what sets it apart: Time links grind and recipe. Differs from counting in your head—comparable day to day.

What it’s for and how to use it: Start at first water–coffee contact (or machine button) → mark bloom/splits → stop at yield.

Cup impact or benefit: See if you’re slow/fast and adjust grind. Teach the same recipe to others.

Technical notes: Scale timer, app or kitchen clock—same start rule always.

Common mistakes: Starting the timer randomly. Ignoring time after one “good” cup.
