The Ratio Eight coffee maker combines precision brewing, top-quality construction, and a design that will elevate any environment. Designed for perfect brewing from 16 to 40 ounces, the Eight uses a smart brewing algorithm to mimic hand-made pour over coffee. 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 delivers water at or near the optimum temperature of 200 degrees. 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.
