Ratio is a Portland, Oregon–based brand creating thoughtfully designed coffee machines for people who value the ritual and flavor of pour-over coffee, without the guesswork. Its brewers automate key steps to help make consistent coffee at home or in the office with simple, intuitive operation. The range includes the Ratio Eight, Ratio Six, and compact Ratio Four, along with the upgraded Eight Series 2, which features dual brew programs and a stainless-steel-and-glass hot water path. Machines use materials such as stainless steel, borosilicate glass, and real hardwood, and come with a five-year warranty.

Ratio also offers curated bundles pairing brewers with grinders and other essentials, plus coffee filters, grinders, mugs, carafes, drippers, storage, kettles, scales, and cleaning and water-quality products. Customers can shop certified refurbished machines, sale items, and gift cards. The brand provides product comparisons, brewing-related journal content, order-status assistance, returns information, and customer support. Ratio’s focus is to simplify daily brewing while delivering the careful control and quality associated with pour-over coffee.
