How much coffee does it brew at once?

Just over 20 ounces, about three 5- to 7-ounce cups. It is not meant for refilling a large pot.

No. It has no integrated grinder, so you grind separately and add ground coffee to the flat basket.

Can I control it from my phone?

No. There is no app control or scheduling; brewing starts from the touch-sensitive button on the machine.

What does the bloom button do?

It pre-infuses the grounds before the main pour, letting trapped gas escape so the coffee extracts more evenly.

Is it good for a small kitchen?

Yes. It is one of the more compact drip brewers, with a detachable water tank and a glass carafe that pours easily.

Does it brew hot enough?

It reaches SCA-recommended brewing temperatures quickly, according to the maker.

Our take on the Ratio Four Coffee Machine

The Ratio Four is a compact drip brewer built to make pour-over style coffee in small batches, just over 20 ounces at a time. A single touch-sensitive button runs a bloom or pre-infusion step, then water flows from a wide steel shower head in one continuous pour. It reaches SCA-recommended brewing temperatures quickly and brews quietly. It suits one or two drinkers who want a simple, well-built brewer without a grinder or app; against rivals it trades programmability and larger carafes for a small footprint and hands-off pour-over results.
