From seed to Sip · Coffee
The Coffee Cup
Why does this coffee taste like this?
The cup is where every earlier decision finally has nowhere left to hide. Genetics, place, ripeness, processing, drying, roasting, grinding and brewing all leave clues. Start with what you taste and work backwards.
Sipping flavour chain
Every stage leaves a trace in the cup. Read the chain left to right — seed to sip.
Follow the flavour backwards
Start with what is actually in your mouth, then work backwards through the likely causes. Some links are strong; others are merely plausible. Coffee is annoyingly fond of having more than one explanation.
Plausible causes for sour, traced upstream:
Cup map
Think of this as the cup’s shape rather than its exam result. Acidity, sweetness, body, bitterness and aroma describe what is there; they do not hand out medals.
Shape only — no quality score, no "better".
Cooling cup
Coffee changes while you are drinking it. As the cup cools, sweetness, acidity, aroma and faults take turns becoming more obvious — which is why the last sip can be far more revealing than the first.
Aroma and sweetness muted; bitterness and roast most obvious.
Cup simulator
Change one thing at a time and watch the cup move. It will not predict every coffee perfectly, but it is a much better way to learn than changing grind, dose, temperature and prayer simultaneously.
Faster extraction → stronger, more bitter if pushed too far.
Directional, not predictive — the real cup depends on the whole system.

Your Coffee Passport
Save the cups you taste and Sipping builds a running taste profile — the origins, roasts, methods and descriptors you return to. It is a passport, not a scorecard: a record of what your palate has met, to help you notice patterns and choose more deliberately next time.
