Welcome to Ratio

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

Our Approach

We design and manufacture coffee machines that are a delight to use for many years. Our customers want delicious coffee without a complex routine. Ratio machines brew beautiful coffee with  the best extraction techniques, via an elegant and simple process.


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.


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.


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

We are inspired by coffee in all of its magical iterations, but the pour-over is perhaps the Ratio’s most relevant ancestor. We’ve done our best to capture that method’s most important elements: the carefully calibrated bloom, the agitation and of course the balanced flavor profile that results.

So what's a pour over?

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

Ratio Story

Our founder, Mark Hellweg, launched his coffee career as a retailer of high-end Italian home espresso machines. One day he had a drip epiphany: most of the filtered coffee makers on the market were disposable appliances with cheap plastic parts and boring, boxy shapes. He set out to design a coffee maker that would be beautiful, well-built, and easy to use.
