A calmer way to adjust your hand grinder
When a cup tastes different from yesterday, changing everything makes the next brew hard to understand. A small notebook and one adjustment at a time are more useful than chasing someone else’s perfect setting.

Keep the starting point simple
Record the coffee, your chosen dose, the amount of water and the grinder setting. Grinder numbers are not universal, so note the setting on your own model rather than copying a number from another device. Keep your usual brewer and pouring routine for the first comparison. This gives you a reference you can actually reproduce.
Change one thing
Move the grind a small amount, then taste the coffee once it has cooled enough to notice its character. Describe the result in ordinary words: sharp, drying, heavy, sweet or flat. These notes are observations, not a score. Water, freshness and pouring can also change the cup, so avoid treating grind size as the only explanation.
Make the useful setting easy to find
When you like a brew, write down the recipe and date. Clean the grinder following its manufacturer’s instructions; do not assume every burr assembly can be washed. Keep a second note for a different bean instead of overwriting the first. A reliable everyday recipe is a better starting point for experiments than a constantly moving target.
