A repeatable brew starts with measurement
Baseline: weigh coffee and water, record grind and time, and change only one variable in the next cup.
Use one baseline, then change one variable
A practical starting ratio for filter coffee is 60 grams of coffee per liter of water, or about 1:16.7. Taste, roast, grinder, water, and brewer can justify a different result. The value of a ratio is repeatability, not obedience.
Method starting points
| Method | Grind | Starting ratio | Main adjustment |
|---|---|---|---|
| Pour-over | Medium-fine | 1:16 – 1:17 | Finer for faster drawdown; coarser for bitterness or stalling |
| Drip machine | Medium | 1:16 – 1:17 | Match basket and batch size |
| French press | Medium-coarse | 1:15 – 1:17 | Longer steep before grinding finer |
| AeroPress | Fine to medium | Recipe-dependent | Change dilution separately |
| Cold brew concentrate | Coarse | 1:5 – 1:8 | Dilute after brewing |
Diagnose the cup
- Sour, thin, quick: grind finer, extend contact, or use hotter water.
- Bitter, dry, slow: grind coarser, shorten contact, or lower extraction.
- Weak but balanced: use more coffee.
- Strong but balanced: use more water.
For mushroom coffee powders
Instant blends dissolve; they do not extract like ground coffee. Follow the stated serving, weigh it when possible, and adjust water for taste without assuming extra powder is medically better.
