Should you buy it?

Buy it if

  • Pour-over flavour without the ritual
  • Design-led kitchens
  • Thermal carafe
  • Bloom phase and slow shower imitate a hand pour

Skip it if

  • Expensive for 40 ounces

  • No timer or brew-strength settings

Not for you? Consider the Technivorm Moccamaster KBGV Select — or see all coffee makers .

The verdict

Ratio designs the Six around a bloom phase and a slow, controlled shower that mimics a hand pour, then holds the result in a double-wall thermal carafe rather than stewing it on a plate. Series 2 keeps the single-button operation and 40-ounce capacity and Ratio backs it with a five-year warranty. It is the premium alternative to a Moccamaster for people who want less countertop drama and a quieter, simpler machine.

What owners say

Amazon owners average 4.1 stars over 63 ratings - a young listing for the Series 2 revision, so the sample is thin compared with the Moccamaster and OXO alternatives.
