Ratio Four Coffee Machine --includes-5-year-warranty There is the obvious utilityMeet 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.
