Seamless Filling

Removable water canister.

Filling your water tank just got way easier. Simply take the removable canister to the sink and fill between 5 and 20 ounces. If you're after precision and want to weigh the water, put the tank on your scale and fill to your target water volume. 

The Perfect Pour Over

Automated Bloom cycle.

Also called pre-infusion, this initial burst of hot water causes freshly roasted coffee to bubble up in a "bloom." The Four then lets the coffee rest and settle back down for 15 seconds before delivering the remaining hot water, leading to a more complete extraction.

Brew It Your Way

Supports multiple filter styles.

The Ratio Four works with several popular filters. It ships with a flat filter basket (for use with Melitta or similar filters) that encourages a consistent extraction, but the Hario V60™, Kalita Wave™, and Origami™ all work perfectly as well.

Features & Specs

Incredible coffee, everywhere.

If you’re familiar with Ratio Coffee, you already know that we build coffee makers that look incredible and produce a brew that would make your favorite barista proud.

The Ratio Four is our smallest brewer yet, an agile, sleek machine that puts out between 5 and 20 ounces of coffee per batch, enough for one to two reasonably sized cups, or one big travel mug. 

The Four uses the exact same technology powering its predecessors, allowing the release of CO2 via a bloom cycle, distributing water across the grounds at precise temperatures via a wide showerhead. 

Weight: 8 lbs
Electric: Powerful 1400 watt/120 volt heating element
Capacity: Brews up to 22 oz / 650 ml (four 5oz cups) 

Consistent water temperature.

The Four's powerful and compact heating element ensures the hot water is between 91-95° Celsius / 195-203° Fahrenheit, which meets the Specialty Coffee Association standards for brewed coffee. 

Wide stainless steel shower head.

The wide shower head ensures the coffee grounds are fully saturated. The shower head is removable without tools for easy cleaning and descaling.
