Make the next cup easier to repeat.
Start with the same coffee, water, dose and brew method for several cups. Change one variable at a time so you can tell what actually improved.
What to pay attention to
Begin with the situation in front of you and the person it affects. Make a short note of what you know, what still needs checking and what a useful next step would look like. Good decisions are easier when observations are kept separate from assumptions.
Keep the context
These notes are an introduction, not a claim of a visit, service or hands-on test. Details can change; check current information before making plans.
