Ratio Six (Series 2)
A
Ranked #5 in Coffee Makers
Backed by 3 cited sources
Covered by 3 outlets
A gorgeous, stainless-and-glass one-button brewer that meets SCA standards with an automatic bloom cycle - praised by Serious Eats-tier reviewers as pour-over quality with zero effort. Costs about $350 for deliberately few features, and the drippy filter-basket handoff is a real annoyance.
