Key ideas in Brewing Better Coffee at Home
- Fats, salts, and sharp acids dissolve into brew water almost instantly.
- Caramelized sugars require sustained contact time and heat to dissolve.
- Heavy plant fibers and bitter chlorogenic breakdown extract dead last.
- Under-extraction pulls fast acids before balancing sweetness can dissolve.
- Under-extracted coffee produces a quick, hollow finish without lingering body.
- A fast brew that leaves a sharp puckering sensation indicates under-extraction.
- Over-extraction leaches heavy tannins that physically dry out your tongue.
- Bitter, ashy notes from deep plant tissue cling to the back of the palate.
- Sour lemon bites indicate under-extraction rather than over-extraction.
- Under-extracted cups feel thin and hollow because heavy sugars are missing.
- Over-extracted cups strip oral saliva through polyphenols, feeling chalky.
- Balanced cups coat the mouth smoothly with extracted lipids and complex sugars.
- The first cup of a split brew captures dense, salty, hyper-acidic solubles.
- The final fraction of a brew contributes pale, bitter, and astringent water.
- Splitting a brew demonstrates how later water dilutes and balances early acids.
- Grinding coarser increases flow rate and shortens brew time
