Which Ratio Coffee Maker Is Right for You? (2026 Canadian Guide)

Our picks at a glance

Ratio makes automatic brewers that run a real pour-over cycle — bloom included — at the press of one button, and the lineup is just three machines. The decision comes down to how much coffee you brew at once and how much you want to spend on design. This guide sorts the Four, Six, and Eight on exactly that.

The short answer:

  • Best overall: Ratio Six — the same brewing approach as the Eight, one button, for much less.
  • Best for one or two people: Ratio Four — a small-batch brewer for a mug or two.
  • Best flagship / design piece: Ratio Eight — the original, with the most presence on the counter.
Model Best for Capacity Controls Approx. price (CAD)
Ratio Four 1–2 cups Small batch One button ~$429
Ratio Six Best overall 40 oz (1.25 L) One button $579
Ratio Eight Flagship / design Full carafe One button ~$1,150

Prices and specs current as of June 2026. The Ratio Six price is Stillwater's; the Four and Eight are Canadian vendor pricing.

Best overall: Ratio Six

  • Price: $579 CAD
  • Capacity: 40 oz (1.25 L)
  • Controls: One button, with an automatic bloom cycle
  • Heating: 1400 W element holding the brew range
  • Highlight: Pour-over results with no settings to manage

Why it shines

The Six runs the same automated pour-over cycle as the flagship Eight — a bloom phase and a held brew temperature — in a leaner body at a lower price. You press one button and get a consistent carafe for two to four people. It is the model that makes the most sense for most kitchens.

Who it's for

You want several cups at once, you like a machine you can leave on display, and you would rather not touch a phone or a menu to get a good brew.

What owners say

Owners praise the build, the quiet operation, and the hands-off consistency. The common note is that it does no single-cup brewing or programming — it does one thing and does it well.

Worth noting

It has no grinder, and drip coffee depends on an even grind, so pair it with a burr grinder such as the Fellow Ode. To see how it stacks up against other premium brewers, see our guide to the best splurge-worthy coffee makers.

Best for one or two people: Ratio Four

  • Price: ~$429 CAD
  • Capacity: Small batch (a mug or two)
  • Controls: One button
  • Highlight: The smallest, lowest-cost way into Ratio

Why it shines

The Four is Ratio's small-batch brewer, built to make one or two cups well rather than half-filling a larger machine. Drip brewers taste best near their rated capacity, so a right-sized machine suits a small daily batch better.

Who it's for

You brew for yourself or two people and want Ratio's approach without paying for capacity you will not use.

What owners say

Owners like the size-to-quality match and the lower price. The common note is simply the small capacity — it is not the choice for entertaining.

Worth noting

If your needs grow, the Six gives you a full carafe for not much more.

Best flagship / design piece: Ratio Eight

  • Price: ~$1,150 CAD
  • Capacity: Full carafe
  • Controls: One button
  • Highlight: The original Ratio, with premium materials and presence

Why it shines

The Eight is the machine the rest of the line descends from, with the most premium materials and the strongest design statement. It brews the same way as the Six but is built and finished as a centrepiece.

Who it's for

You want the flagship look and finish and the design matters to you as much as the coffee.

What owners say

Owners love the materials and the way it looks on the counter. The common complaint is the price relative to the Six, which brews a very similar cup for far less.

Worth noting

If the cup matters more than the statement, the Six is the value pick by a wide margin.

How to choose

  • By batch: One or two cups, the Four. A full carafe for a household, the Six or Eight.
  • By budget: ~$429 for the Four, $579 for the Six, ~$1,150 for the Eight.
  • By priority: Want the best value cup? The Six. Want the flagship design? The Eight.

Frequently asked questions

What is the difference between the Ratio Six and Ratio Eight?

Both run the same automatic pour-over cycle with a bloom. The Eight uses more premium materials and has a larger presence and price; the Six delivers a very similar cup for much less.

Does a Ratio coffee maker have a grinder?

No. All three brew from pre-ground coffee, so pair them with a separate burr grinder for the freshest results.

Can a Ratio brew a single cup?

The Four is built for small batches of one to two cups. The Six and Eight are designed for full carafes rather than single servings.

Are Ratio coffee makers worth it?

For people who want genuine automated pour-over with a design-forward machine, the Six in particular is strong value. The Eight is worth it mainly if the flagship finish matters to you.

The picks in full

RATIO Six Coffee Maker (120V) (Series 2)

Best overall

Ratio Six

One button starts everything. The Ratio Six pours water over the grounds the way a person making pour-over would, wetting them first and pausing to let them settle, then metering the rest of the water at a steady rate. A 1.25 litre carafe takes about eight minutes.

What's good

  • One button, with nothing to set
  • Wets the grounds first, then pours steadily
  • Carafe has no moving parts and opens wide to clean

What to know

  • About eight minutes for a full carafe
  • Nothing to adjust if you like tuning a brew
RATIO Four Coffee Maker (120V) (Series 2)

Best for one or two people

Ratio Four

Brews between 5 and 20 ounces, so it makes one or two mugs rather than a pot you will not finish. It wets the grounds first and pauses to let them settle, the way a person making pour-over does, then finishes in about four minutes. Water reaches the coffee between 91 and 95 degrees.

What's good

  • Brews from 5 to 20 ounces, so nothing is wasted
  • Blooms the grounds before the main pour
  • 11.5 inches tall, fits under most cupboards

What to know

  • Glass carafe with no hot plate, so pour it soon
  • Too small for a household brewing a pot at once
Ratio Eight

Best flagship / design piece

Ratio Eight

The original Ratio, and the machine the Six was built down from. A full 40 ounce batch takes eight to ten minutes, and it brews into either a hand-blown glass carafe or a double-walled steel one. Like every Ratio it uses no hot plate, so the coffee is never cooked while it waits.

What's good

  • Choice of hand-blown glass or double-walled steel carafe
  • No hot plate, so the coffee is not cooked as it sits
  • 40 oz batch, six to eight cups

What to know

  • Eight to ten minutes for a full carafe
  • Roughly double the price of the Six for the same 40 oz
