• INCREDIBLE COFFEE, EVERYWHERE

  When Ratio introduced the Four in 2024, it quickly became a favourite for those who wanted a small batch brewer with the same design ethos and performance as their larger machines. The first production run sold out in just over 6 months!

  Guided by feedback, Ratio re-tuned, refined, and elevated. The result: the Ratio Four Series 2 - an even more polished take on their compact classic.

  What's new in the Series 2

  Refined Showerhead - Redesigned for better, even extraction across the coffee bed, bringing balance and consistency to every cup. Ratio tested various showerhead sizes and designs to find the one that produced an even water distribution.
  Updated Filter Basket - With a new extended handle and smoother rails, the basket is easier to insert and remove so you don't bump the start button by accident.
  Updated Pump - Now brews at a hush. Ratio fine-tuned the pump to be even more silent than before, allowing for a relaxed morning routine.
  Tuned Button Sensitivity - Adjusted to eliminate accidental brew, giving you a more confident start every time.
  Pulse Timing Improvements - Subtle adjustments to the pulse pour deliver a higher end-brew temperature for optimal extraction and enjoyment.

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

  The Four is Ratio's 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, the Eight and the Six, allowing the release of CO2 via a bloom cycle, distributing water across the grounds at precise temperatures via a wide showerhead.

  As Easy As Pods, But So Much Better
  Ever wonder what the convenience of a Keurig really costs? On average, $33-$50 a pound, depending on the roaster. For mediocre coffee, brewed with haste and waste at the forefront, into throwaway plastic pods. Buy fresh from your local roaster and have the Four brew up a cup - the taste will be monumentally better.

  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.

  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.

  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.

  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.
