Sour coffee: what to check

Unpleasant acidity can have different explanations. Check the brew first and describe the sensation. Keep the same coffee, method and recipe while testing just one change below.

Try changing first

Choose one experiment your equipment allows. Compare using the same coffee and recipe. This list is neither a diagnosis nor a sequence of changes to make all at once.

  1. Change 1 of 3

    Check the steps

    Verify quantities, time and execution. A skipped step is different from a recipe that needs adjusting.

  2. Change 2 of 3

    Try a finer grind

    With an adjustable grinder, try a small relative change. Keep coffee, water and temperature steady for comparison.

  3. Change 3 of 3

    Try a higher temperature

    Only if your equipment allows control, test within the recipe’s range. Acidity does not establish a diagnosis of underextraction.
