CoffeeRate was built to bring measurement-driven methodology to every level of specialty coffee, from home enthusiasts to professional baristas.
CoffeeRate started from a straightforward observation: most online brewing guides give ratio recommendations without the context to apply them correctly. A 1:16 ratio means something different at different roast levels, with different water, on different brewers. The gap between a published recipe and a good cup is often filled only by years of hands-on experience.
The tools and articles on this site are built to close that gap. Each calculator uses validated parameters drawn from SCA research, lab testing, and input from working baristas. Each article is written by a named expert with direct experience in the topic — no aggregated SEO content, no vague generalizations.
As of March 2026, CoffeeRate tools have processed 4,217 calculations for brewers across 38 countries. The site remains free, without registration, without advertising, and without affiliate links in editorial content.
Every parameter in our tools is grounded in published research or validated through controlled brewing tests. No numbers are invented for convenience.
Rounding to the nearest convenient number produces mediocre coffee. We provide specific values and explain why precision in measurement matters at every step.
Professional-grade brewing knowledge should not be gated behind paywalls or certification courses. CoffeeRate's tools are free and will remain free.
Every article carries a named author with verifiable expertise in the subject. Anonymized or AI-generated content has no place in a site built on trust.
Three specialists who contribute directly to the tools and editorial content.
Marcus has trained baristas across specialty cafes in the UK and North America. He leads the extraction science curriculum and validates tool parameters against refractometer data.
Elaine advises cafes on equipment selection and recipe standardization. She contributes the brew method comparisons and equipment-specific guidance on the site.
Daniel's background is in analytical chemistry. He brings laboratory-level rigor to water chemistry content and tests how mineral profiles affect extraction across brew methods.
