New, but familiar. Introducing Four Series 2.

The small batch brewer, refined.

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

We weren’t content to leave it there. Guided by your feedback, we re-tuned, refined, and elevated. The result: the Ratio Four Series 2—an even more polished take on our compact classic.

What's new in the Series 2:

• A new look - Meet Linen, a soft neutral finish paired with a clear borosilicate glass carafe for a clean, timeless look.
• Refined Showerhead - Redesigned for better, even extraction across the coffee bed, bringing balance and consistency to every cup. We 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. We 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.

Same idea, even better execution
The Ratio Four remains the same at its core; a brewer designed for smaller batches without compromising on flavor or design. With the Series 2, it becomes even more intuitive, consistent, and enjoyable to use.
