Welcome to Ratio

We design and build coffee makers for people who love coffee and good design.

Our Approach

 1

Simplify your routine.

The Ratio removes variables like water temperature, extraction time, and pour over pattern so you can worry less about making your coffee, and more about drinking it.

 1

Elevate your taste.

Making coffee shouldn’t feel like a compromise. We’ve engineered a pour over style system with the precision of high-end espresso machines. You’ll taste the difference.

 1

Enjoy it for life.

No plastic screws, tubes, or environmentally harmful pods. Ratio is hand assembled in the USA from cast metal, borosilicate glass, and real hardwoods.

Art of the Pour Over

So what's a pour over?

It’s exactly what it sounds like: coffee brewed manually, affording complete control to the brewer.
