Ratio Eight Coffee Maker - White/Walnut

Finished in a crisp gloss white powder coat with dark walnut wood trim, the Ratio Eight in White combines precision brewing technique, top-quality construction, and a design that will elevate any environment.

With the ability to bloom and brew, this coffee maker has the ability to replicate the pour-over process with the push of a button. It heats the water through a die-cast aluminium element to the ideal temperature and precisely monitors the water flow through a stainless steel shower head, ensuring the perfect cup of coffee every time.


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 aluminium, borosilicate glass, and a selection of premium hardwoods.

Under the hood.

A die-cast aluminium element heats water to an ideal extraction temperature. The water flows through a stainless steel shower head designed for even distribution over the grounds.

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 freshly 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 aluminium 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 built-in obsolescence and a life span of maybe 1-2 years, Ratio is designed to last.

Die-cast metal and hand sanded wood.

You really have to see the Eight in person to understand the fine details of each part. It is built more like fine furniture than a coffee maker. The Eight weighs a touch over 14 pounds thanks to the heavy-duty cast metal, wood, and glass components.

Brew from 2 to 8 cups.

Choose from a BPA-free copolymer or handblown borosilicate glass water tank with accurate markings for full (40 ounces / 1.2 litres of brewed coffee) and a half (20 ounces). With either tank choice, once the water is heated it flows through handblown glass supply lines before hitting the stainless shower head.

Handblown glass.

Each Ratio Eight ships with a handblown borosilicate glass carafe that holds a Chemex paper filter or the stainless steel Ratio Kone. Each carafe will have slight differences due to its artisan handblown nature, lending a subtle contrast to the perfection of the cast metal.
