Coffee Tools
Free interactive tools built on our database of 619 specialty coffees — calculators, a taste-match quiz, a roaster map, and more.
Frequently Asked Questions
Are these coffee tools free to use?
Yes — every tool on this page is free, with no signup or account required. Each one runs entirely in your browser and draws on our database of 619 specialty coffees from 100 roasters.
Which coffee calculator should I use first?
Start with the Brew Ratio Calculator if you’re dialing in a new brew method, or the Caffeine Calculator if you’re managing intake. Already own beans? The Coffee Freshness Checker tells you if they’re still at peak flavor.
What data powers these tools?
The calculators combine standard brewing references — the SCA Brewing Control Chart, published caffeine-content ranges by method, and roast-staling curves — with our own catalog of coffees, roasters, and flavor notes for tools like Compare and Find Your Coffee.
Do the calculators work for any brand of coffee, not just what’s on this site?
Yes. The Brew Ratio, Extraction, Caffeine, Cost Per Cup, Coffee for a Crowd, Coffee to Water Ratio, Freshness, and Water Quality tools all accept your own numbers and work with any bag of coffee. Only Compare, Find Your Coffee, and Coffee DNA are limited to coffees in our catalog.
How often is the tool data updated?
The underlying coffee catalog — prices, availability, and roaster counts — is rebuilt continuously as our database changes. Reference values used in the calculators (brewing ratios, caffeine ranges) follow established SCA and industry standards and change rarely.
