Cool Material: "Perfect for any counter."

Over the years we have received many requests for a more compact Ratio brewer, from hotel owners, Airbnb hosts, Airstream owners, people who just drink a cup or two of coffee. We're thrilled to offer the Ratio Four, a compact yet powerful brewer.

"Ratio has taken its impressive countertop coffee brewer and shrunk it down for even the smallest of kitchens. The Four is a "half batch" pour over brewer perfect for any counter."
