Meet Ratio Four: the first affordable and beautiful “half batch” pour over coffee machine. The Four is our smallest brewer yet, an agile, sleek machine that puts out between 5 and 20 ounces of coffee per batch, enough for one to two reasonably sized cups, or one big travel mug. Brews with a bloom cycle in about 4 minutes or less. Removable water tank can be positioned on the left, the right, or behind. Small enough to fit on any countertop at just 11.5" tall and 7.5" wide. Built to last, and backed by a five-year warranty.
