Summary
Wirecutter's top drip pick and CNET's best overall — it nails SCA Golden Cup standards with a programmable timer that the Moccamaster lacks. A strong choice for people who want convenience alongside quality.
The go-to for coffee drinkers worried about microplastics — metal feed lines, minimal plastic contact with hot water, and exceptional brew quality. A cult favorite in r/Coffee.
Pros
  • SCA-certified Golden Cup brewer for optimal extraction
  • Programmable auto-brew timer — only top pick with this feature per Wirecutter
  • Compact and stylish design fits most countertops
  • Consistently top-ranked by both CNET and Wirecutter in independent testing
  • Metal feed lines minimize hot water contact with plastic
  • Produces excellent, clean-tasting drip coffee
  • Praised by coffee enthusiasts for build quality and aesthetics
  • Paper filter use further reduces plastic exposure
Cons
  • 9-cup capacity is smaller than many competing models
  • Plastic components raise some concerns for microplastic-conscious buyers
  • Less community buzz than the Moccamaster among coffee enthusiasts
  • Stock dripper is plastic on the base Ratio Six model
  • Expensive at ~$370 for the entry-level version
  • Carafe lid/spout is plastic, so coffee does touch plastic when pouring
Our take
The OXO is the pick for people who want great coffee AND the ability to wake up to a pre-brewed pot. It's the most feature-complete quality drip maker under $300.
If you've gone down the microplastics rabbit hole, the Ratio Six is the answer at a price that doesn't require selling a kidney. The community loves it for a reason.
