Better coffee starts with measurements you can trust

Bean Ratio is an independent educational site for home coffee brewers. We turn coffee-to-water ratios, grind settings, water temperature, and brew time into practical instructions you can use at the counter.

Our calculators perform transparent arithmetic; our guides explain why the numbers work and where personal taste should take over. Recommendations are starting points, not paid placements or substitutes for testing a recipe with your own beans and equipment.

Bean Ratio is written and maintained by Brad Erickson. Every published guide is reviewed for measurement consistency, clear sourcing, and usefulness before it is updated. When an article materially changes, its modified date changes too.
