The Open Box Ratio Four proves that sometimes, all you need is a fresh cup of coffee. Designed to brew up to 20 ounces of coffee with minimal fuss, the Open Box Ratio Four features a simple flat basket design, easy-pouring glass carafe, and a removable water tank on its own base that can be positioned wherever is most convenient for your setup. A single, touch-sensitive button automatically blooms your coffee before starting your brew. Brewing is both swift and silent, rapidly hitting the SCA-recommended temperatures before distributing water in a continuous pour through a wide steel shower head. More than the sum of its parts, the Open Box Ratio Four’s attention to ergonomics, high quality coffee, and speedy brewing make it one of the best compact coffee makers on the market.
