Ratio Six

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 its older sibling at a leaner cost, slimmer profile, and lighter weight. All despite having the same brewing capacity (1.25 liters) 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 near the ideal temperature (93º). 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.

Modern Quality

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, every Ratio is built to last and covered by a 2-year limited warranty.

• The optional heat shield completely surrounds the shower head during brewing, increasing the extraction of your coffee and producing a very hot cup of coffee, all while keeping within the industry-accepted standards for coffee brewing. The coffee is typically just shy of 93° C at the end of the brew cycle. For those that prefer their coffee really hot, or add lots of milk or cream, the heat shield is a great brewing accessory.
