The Ratio Eight detects the water in the tank and changes the brew cycle automatically given the amount of liquid. This allows for perfect partial batch brewing, anywhere from 16 to 40 ounces. The Ratio is equipped with a powerful die-cast 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. The water flows through a stainless steel shower head designed for even distribution over the grounds.

We believe quality design deserves the best materials. That’s why the Ratio Eight, built with precision-machined aluminum, BPA free polymer, and a selection of premium hardwoods, has become one of our all-time favorite coffee makers. Designed in Portland, Oregon, every Ratio machine is meticulously assembled by hand just one block from our showroom and HQ. 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 Cobalt and Silver models have a satin finish and the White and Oyster have a semigloss finish.
