Ratio Six Coffee Machine (Certified Refurbished)

What is the capacity of the Ratio Six?

It brews up to 40 ounces (1.25 liters) at a time—great for serving multiple people or enjoying several cups throughout the morning.

The tank is Tritan, and once brewing begins, water only comes into contact with stainless steel, borosilicate glass, aluminum, and FDA-approved silicone.

Yes. Pairing the Six with the Eight Series 2 stainless dripper and thermal carafe creates a completely plastic-free hot water brew path. The Ratio Brew Pad helps align everything perfectly on the base.

The Six has a flat-bottom basket compatible with 8-12 cup flat-bottom paper filters or the Able Basket reusable filter.

Ratio machines don’t use a hot plate. Hot plates tend to overheat coffee, causing bitterness and a burnt flavor over time. Instead, our brewers have the option to be paired with a double-wall stainless steel thermal carafe that keeps coffee hot long enough to enjoy a full pot without altering the taste. If you prefer a glass carafe, we recommend serving right away or transferring your brew to an insulated vessel for the best flavor and temperature.
