How to use the Coffee Kick
Coffee brewing is a precise extraction process. Ratio, grind size, water temperature, and contact time all interact to determine the flavor of the final cup.
The golden ratio
Most brewing methods target 1:15 to 1:17 (coffee:water by weight). That's 1g of coffee per 15–17ml of water. Espresso uses 1:2 (a 20g dose pulls a 40g shot). Stronger or weaker preference? Adjust the ratio before adjusting brew time or temperature.
Extraction and TDS
- Under-extracted: sour, salty, thin. Fix: finer grind, longer contact time, or higher temperature.
- Over-extracted: bitter, astringent, harsh. Fix: coarser grind, shorter time, or lower temperature.
- Water temperature: 90–96°C (195–205°F) for most methods. Espresso: 90–94°C.
Brine for cold brew
Cold brew uses a 1:8 ratio (coarse grind) steeped 12–24 hours in cold or room-temperature water. Lower temperature slows extraction, requiring more time — but produces a smoother, less acidic result.
Frequently Asked Questions
How accurate are the results?
The Coffee Kick applies a standard formula to your inputs — accuracy depends on how precisely you measure those inputs. For planning and estimation, results are reliable. For high-stakes or professional decisions, cross-check the output with a domain expert or primary source.
Why do my results differ from other converters?
Volume-to-weight conversions depend on the specific ingredient and its packing density. A 'cup of flour' can range from 110g (sifted) to 155g (packed) — a 40% difference. For baking precision, weigh ingredients rather than measuring by volume.
How should I interpret the Coffee Kick output?
The result is a calculated estimate based on the formula and your inputs. Compare it against the reference values or benchmarks shown on this page to understand whether your result is high, low, or typical. For decisions with real consequences, use the output as one data point alongside direct measurement and professional advice.
When should I use a different approach?
Use this calculator for quick, formula-based estimates. If your situation involves multiple interacting variables, time-varying inputs, or safety-critical decisions, consider a dedicated software tool, professional consultation, or direct measurement. Calculators are most reliable within their stated assumptions — check that your scenario matches those assumptions before relying on the output.
