    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 consistently delivers water at the ideal temperature of 200°.

    Inspired by the precision of manual brewing with pourover kettles, Ratio uses a unique showerhead design to uniformly saturate the coffee grounds. This means a more complex cup of coffee for you - without extra complexity in your routine.

    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.

    Good Morning: Your Coffee Machine is Ready

    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 with a satin nickel ceramic finish contrasts with Oregon black walnut and borosilicate glass.

    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.
