One Button Simplicity
Simplify your coffee routine to the touch of a button. The Ratio Six’s Bloom, Brew, and Ready phases run in sequence, delivering a perfect (and easy) cup of coffee every time.
Deliciously Simulated Pourover
The Ratio Six simulates a skilled barista pourover process, precisely metering water flow through both the bloom and brew phases. All of the taste. None of the work.
Under the Hood
Utilizing the same die-cast aluminum heating element as the Ratio Eight, water flows evenly through the stainless steel shower head and over the grounds at the ideal extraction temperature.
Designed for today. And tomorrow.
We designed the Ratio Six for longevity with precision formed stainless steel, borosilicate glass, and high end BPA-free copolymers. Every inch is built to last and covered by a 5-year warranty.
Delicious Coffee. Simplified.
At Ratio, we believe everyone should be able to enjoy world-class coffee without the fuss. Which is why we build coffee machines for flavor, precision, simplicity, and beauty—no more and no less. We call it “convenience without compromise.” Our customers call it “I’m never buying another coffee maker again.”
Thanks to Ratio Six, the world’s best coffee is more accessible than ever.
Featuring unique materials and an innovative build process, the Ratio Six delivers an experience comparative to it’s older sibling at a leaner cost, slimmer profile, and lighter weight. All despite having the same brewing capacity (1.25 liters / 40 ounces) and powerful 1400 W heating element.
Less Thinking. Better Drinking
Sometimes you just want a great cup of coffee without having to think about time, temperature, and other variables. Which is why Ratio has just one button and no complicated programming.
After the button is pressed, Ratio simulates a skilled barista pourover process: First, hot water is dispersed through a stainless steel spiral showerhead across the grounds, causing a bubbly interaction called a “bloom.” The control board allows the bloom to settle before delivering the rest of the hot water slowly at the perfect temperature (200º). The result? More evenly extracted grounds and a more amazing cup of coffee.
After brewing, simply discard or compost the used paper filter and rinse out the thermal carafe with hot water. That’s it. For deep cleaning—we recommend twice a month—Ratio Wash keeps the water tank and carafe sparkling clean.
There are coffee machines that make great coffee, and there are coffee machines that look great. Ratio Six is both, combining form and function.
Designed in Portland, Oregon, every Ratio machine is meticulously assembled by hand. While common appliances often have a built-in obsolescence and 1-3 year life span, every Ratio is built to last and covered by a 5-year limited warranty.
The Ratio Six ships with a thermal carafe designed for flat-bottom basket coffee filters. Prefer a conical filter? You can also use the Ratio Eight Thermal Carafe or Glass Carafe with a Chemex paper filter or stainless steel reusable Ratio Kone. Both the Ratio Six and Eight have the same brewing capacity (1.25 liters / 40 ounces).
