A calmer way to improve your home brew

A repeatable recipe makes small experiments easier.

Write down the starting point

Record your coffee dose, water amount, method and grind setting. Use a recipe you can repeat before changing it.

Try a small grind adjustment while keeping the other settings steady. Taste and record the result rather than assuming a change must be better.

Brewing is an experiment in your own preferences. Keep the version you enjoy and use it as your next starting point.
