Forbes: Six is "best splurge coffee maker."
Forbes did a deep dive on the Ratio Six:
"Slick and streamlined is the name of the game here: The Ratio Six is a gorgeous, well-designed machine that simply produces excellent coffee. Setup is as simple as it gets (and Ratio gets bonus points for packing the stainless-steel machine and its mostly metal parts in completely recyclable, plastic-free materials). The machine comes pre-rinsed and flushed, so it’s ready to roll—a thoughtful touch that only applied to this machine and the Technivorm Moccamaster. Just place a flat-bottom filter with your weighed coffee grounds in the filter holder and screw on an optional heat shield, stack that on top of the insulated thermal carafe, fill the water reservoir and press the coffee maker’s single button. That’s it.
The machine then goes through a short blooming cycle to hydrate the grounds before brewing with a shower head-style water dispenser. You get a full pot in about eight minutes, with water temperature just shy of 200 degrees—right on the money from the SCA’s point of view. What results is a really great-tasting cup with a lot of the nuances that come from pour-over brewing methods. It’s also a cup that stays conveniently warm in its thermal carafe for several hours with the insulated lid (even four hours after brewing, I found that it measured a solid 168 degrees).
