For heat retention, you can transfer your brew into a thermal vessel.Is the Ratio Four programmable?
Like all Ratio machines, the Four uses a simple one-button start for an intuitive, manual brewing experience.

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.

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.

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.

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