Eight Coffee Maker


The Ratio Eight Coffee Maker combines precision brewing technique, top-quality construction, and a design that will elevate any environment. Simulating a skilled barista pour over, the Ratio meters the water flow to create a bubbly interaction called "the bloom”. The result is more evenly extracted grounds and a more amazing cup of coffee.

The Ratio Eight detects the water in the tank and changes the brew cycle automatically given the amount of liquid. This allows for perfect partial batch brewing, anywhere from 16 to 40 ounces. The Ratio is equipped with a powerful die-cast 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. The water flows through a stainless steel shower head designed for even distribution over the grounds. 

We believe quality design deserves the best materials. That’s why we built the Ratio Eight with precision-machined aluminum, borosilicate glass, and a selection of premium hardwoods. Designed in Portland, Oregon, every Ratio machine is meticulously assembled by hand. There are coffee machines that make great coffee and there are coffee machines that look great. Ratio is the first coffee machine that is truly both, combining form and function.

    Ratio Kone by Able

    A custom-made reusable metal filter for the Ratio Eight. Ratio teamed up with Able Brewing to create this metal conical filter specifically for the Ratio Eight Coffee Machine.

    The Kone's unique design and photochemically etched holes allow the water to flow freely through the entire filter, not just out of the end. For the Ratio Eight version, the Able team added more holes to accommodate the higher brew volumes of up to 40 ounces. The holes are round on one side and square on the other - a rare design feature that helps to eliminate potential clogging.

    Made of laser-welded stainless steel in the US, the Kone allows just the right amount of oils and sediment to pass through, giving the coffee a rich flavor that is still clean, aromatic, and delightful. The mouth feel will be slightly fuller than a Chemex filter but cleaner than a typical stainless steel filter.

    Baratza Virtuoso Coffee Grinder

    Baratza’s well-regarded burr grinder that has earned a reputation for simplicity and durability. With a choice of 40 distinct grind settings, you can produce the ideal coffee particle size for your coffee maker - from french press to a fine drip or Aeropress. And all at the lower RPM settings needed to avoid heating the grind. The Virtuoso is built ruggedly, yet with those classic Italian lines - making it a great addition to your kitchen.

    Solidly stable, the Baratza Virtuoso is relatively quiet in part due to the lower motor speed, operating at a third of the RPM of many other competitors. This motor efficiency allows your beans to remain cool while also reducing noise and static buildup. Grind settings can be quickly chosen and will remain stable, day after day. This is the device for the serious coffee drinker who seeks the commercial quality grinding performance of conical burrs.
