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 delivers water at or near a temperature of 200 degrees. Gathering feedback from champion baristas and our customer base we have developed a machine that emulates a manual pour-over, fine-tuned to provide a sweet cup that lacks bitterness. 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.
