Coffee Brewing Guides

In-depth guides on coffee-to-water ratios, brew methods, grind size, and extraction science. Whether you're dialing in your first pour over or troubleshooting a bitter espresso, these articles explain the why behind the numbers in our coffee ratio calculator.

Every guide here is written and reviewed by our editorial team of home brewers and specialty-coffee enthusiasts. We calibrate every ratio and recipe against the SCA Golden Cup Standard and cross-reference against James Hoffmann's The World Atlas of Coffee and Scott Rao's The Professional Barista's Handbook. Nothing on this page is sponsored, ghostwritten, or generated. If a recipe here doesn't match the cup you get, tell us — we retest and publish corrections in the article's update log.

New to home brewing? Start with the coffee-to-water ratio guide, then the SCA Golden Cup explainer. After that, dive into a method-specific article for whatever brewer sits on your counter and use the free printable brew log to track what you change.
