Ratio Six Coffee Machine

Delicious coffee, simplified.

At Ratio, we believe everyone should be able to enjoy world-class coffee without the fuss. Which is why we build coffee machines for flavor, precision, simplicity, and beauty—no more and no less. We call it “convenience without compromise.” Our customers call it “I’m never buying another coffee maker again.”

Thanks to Ratio Six, the world’s best coffee is more accessible than ever.

Featuring unique materials and an innovative build process, the Ratio Six delivers an experience comparative to its older sibling at a leaner cost, slimmer profile, and lighter weight. All despite having the same brewing capacity (1.25 liters / 40 ounces) and powerful 1400 W heating element.

The Series 2 features an entirely updated carafe that has no moving parts. We made the spout more pronounced, leading to a better pour of your favorite coffee. The opening of the carafe is large enough to fit your hand inside for a thorough cleaning, and mates perfectly with the original Series 1 filter basket.

Modern quality.

The Ratio Six coffee maker is built with thick, precision stamped stainless steel with a satin stainless steel or matte black finish.

Laboratory grade handblown borosilicate glass water lines.

BPA-free copolymer water tank with water markings from 2 to 8 cups, with accuracy to within 1 ounce. The tank holds 44 ounces / 1.3 liters of water at the full mark, with roughly 10% of that volume absorbed into the coffee grounds. 44 ounces poured into the water tank should yield about 40 ounces  of brewed coffee. 

Unique heat shield.

The unique Ratio Six heat shield completely surrounds the shower head during brewing, increasing the extraction of your coffee and producing a very hot cup of coffee, all while keeping within the industry-accepted standards for coffee brewing. The coffee is typically just shy of 200 degrees F at the end of the brew cycle. For those that prefer their coffee really hot, or add lots of milk or cream, the heat shield is a great brewing accessory. Prefer a more open brewing style? You can simply pull on the silicone heat shield to remove it from the lid, and they can be easily reconnected.
