Ratio Six (Series 2).
Single-temperature precision (no menus, no presets), satin stainless or matte black, thermal carafe upgraded over Series 1.
The Verdict.
Gavler Meta-Score
“The aesthetics-first pick that doesn't compromise on the brew. Ratio's restraint — one switch, one temperature, no menus — is a coherent design statement, and the Series 2 thermal carafe + 5-year warranty close the practical gaps the original Six had. If the Moccamaster's powder-coat look reads as too industrial for your kitchen, the Six is the alternative that doesn't trade brew quality for design.”
The Gavler Verdict
Precision Engineering
Made in Oregon
Designed and assembled in Portland, Oregon with a 5-year warranty — the brewer Ratio expects to outlast the typical kitchen-appliance replacement cycle.
Thermal Carafe (Series 2)
Insulated stainless thermal carafe replaces the original Six's glass kettle — coffee holds at temperature for ~90 minutes without a hot plate degrading flavor.
Intentional Simplicity
One switch, one brew temperature, no programming. Ratio's editorial position is that the right brew temperature is settled science — the home brewer's job is good beans and proper grind.
Technical Specifications
The Scoreboard
Design-forward audience rates it very highly; coffee-spec purists note it offers no programmable controls and lacks formal SCA certification.
