Support This Site

This site is free to use and always will be — every ratio, every fix, every calculator stays open with nothing paywalled behind a login. Keeping it accurate takes real time: checking a ratio range against current specialty-coffee sources, rewriting a fix page when a better explanation exists, adding a method that readers keep asking about. If it's been useful, there are two direct ways to support that work.

Buy the logbook

The Coffee Dial-In Logbook is a $9.99 printable worksheet set — a dial-in sheet for every method, a ratio quick-reference card, and a tasting log. It's genuinely useful on its own, and buying it funds the site at the same time.

Or just contribute

If the logbook isn't for you but the site has still saved you a bad pot of coffee or two, a direct contribution — whatever you'd spend on a single cup, or more if you'd like — goes straight toward hosting, research time, and adding new content. There's no tier system and no perk attached; it's a straightforward way to say the site was worth something to you. Contributions are a single payment through Stripe — nothing recurring, and no card details are stored here. The minimum is $5, mostly to keep card-processing fees from eating an outsized share of a smaller amount; above that, whatever feels right is the right amount.

Where the money actually goes

Hosting costs are small and predictable; the bulk of what a contribution funds is time spent checking sourced figures, rewriting pages that turn out to be unclear, and researching new methods and bean topics readers ask about. There's no team and no office behind this — it's a small, focused reference site, kept that way on purpose.

Free ways to help, if you'd rather not spend anything

Sharing a specific page with someone who's asking the exact question it answers is worth more than it sounds — that's how a reference site like this one actually reaches the people who need it. Pointing out a ratio that seems off, a method that's missing, or a fix that didn't work for your setup is just as valuable; every one of those reports gets read and, where it holds up, acted on.
