How to use this archive page
Scan the titles for the symptom that sounds closest to your cup, then read the article that names the same clue. Bitter coffee can come from over-extraction, a too-fine grind, stale oils, water that tastes rough, coffee held on heat, uneven flow, or beans that simply do not fit your taste. The safest move is to choose one likely cause and run one controlled test before changing anything else.
If several articles sound relevant, start with the cheapest check: clean the brewer, keep the recipe steady, taste fresh coffee before it sits, and make only a small grind or time change. That gives the next cup enough structure to teach you something.
