Hario's Cold Brew Coffee Pots are designed with classic engineering details to ensure that maximum flavor is extruded from every grain of coffee placed in their suspended filters. Unlike other presses, the Hario takes cold or room temperature water and yeilds cold brewed coffee in 12-24 hours. It is the perfect quality and flavor for iced coffee drinks. The Mini Pot brews 1-2 cups of coffee. The larger size brews 2-4 cups of coffee.
