Ratio Eight Features
One Button Operation
The Ratio Eight detects the water in the tank and changes the brew cycle automatically given the amount of liquid. Just one touch and it all magically comes together.
Strength Of Character
We believe quality design deserves the best materials. That’s why we built the Ratio Eight with precision-machined aluminum, borosilicate glass, and a selection of premium hardwoods.
Under The Hood
A die-cast aluminum element heats water to an ideal extraction temperature. The water flows through a stainless steel shower head designed for even distribution over the grounds.
Deliciously Simulated Pour-Over
The Ratio Edition coffee maker simulates a skilled barista pour over, precisely metering the water flow during both the bloom and brew phases. All the taste without the work.
About Ratio Eight
Engineered For Extraordinary Coffee
Ratio is smarter than your average coffee maker. Beneath the exterior is precise brewing science, automated. Ratio is equipped with a powerful heating element. Where lesser machines struggle to maintain the optimum temperature – brewing either too hot or too cold – Ratio delivers water at or near the optimum temperature of 200 degrees.
Gathering feedback from champion baristas and our customer base, we have developed a machine that emulates a manual pour-over, fine-tuned to provide a sweet cup that lacks bitterness.
Hot water poured over fresh roasted coffee causes a bubbly interaction called a “bloom.” The control board of Ratio applies a bloom cycle that allows the bloom to settle down before delivering the rest of the hot water. The result? More evenly extracted grounds and a more amazing cup of coffee.
Less Thinking And Better Drinking
Sometimes you just want a great cup of coffee without having to think about time, temperature, and other variables. We agree, which is why Ratio has just one button and no complicated programming. The subtle white lights on the front of the machine will tell you what’s happening with the brew cycle, but you probably have better things to do like catch up on your morning read. Ratio won’t mind at all.
Whether a 40-ounce carafe for the party or a 16-ounce cup for the road, both should be equally easy and delicious. That’s why we designed Ratio to automatically determine the amount of water you’ve added to the tank and adjust the brewing time accordingly.
You shouldn’t have to be a trained barista to make great coffee, and you shouldn’t have to be an engineer to clean your coffee maker. After brewing, simply rinse out the sturdy glass carafe with hot water, discard or compost the used paper filter, and you’re done. For deeper cleaning every other week or so, Ratio cleaning detergent will keep the water tank and carafe sparkling clean.
The Finest Materials
There are coffee machines that make great coffee and there are coffee machines that look great. Ratio is the first coffee machine that is truly both, combining form and function.
The materials chosen for the Ratio machine juxtapose the precision of high-tech with the irregularity of natural finishes. Precision die-cast aluminum bases with premium coatings are contrasted with figured hardwood.
Designed in Portland, Oregon, every Ratio machine is meticulously assembled by hand. While common appliances often have a built-in obsolescence and a life span of maybe 2-3 years, Ratio is designed to last.

Ratio’s Eight designed by a Portland, Ore., company that is to coffee what vintage Marantz was to stereos. It’s by nerds, for nerds. Under all that brushed nickel and polished wood is a serious machine.
