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 (200º). The result? More evenly extracted grounds and a more amazing cup of coffee.
