Know before you buy
The machine mimics a manual pour-over process by automatically managing the Bloom, Brew, and Ready phases. It uses a stainless steel shower head to distribute water evenly over the grounds, ensuring consistent extraction without you needing to monitor the process.
No, the Ratio Six does not include a built-in grinder or water filtration system. You will need to use a separate burr grinder and we recommend using filtered water for the best flavor results.
The water reservoir is fixed and not removable. You will need to fill it directly using a pitcher or carafe.
No, the components of the Ratio Six are not dishwasher safe. We recommend hand-washing the thermal carafe and filter basket with warm, soapy water to maintain their longevity and performance.
The Ratio Six uses standard flat-bottom basket paper filters. These are widely available and help ensure a clean, sediment-free cup of coffee.
The thermal stainless steel carafe is designed to retain heat effectively after the brew cycle finishes. While it does not have a heating plate—which prevents the coffee from burning or becoming bitter—it keeps your coffee at an ideal serving temperature for an extended period.
