Handmade in Japan where cold brew (Kyoto-style) coffee originated, this is the slow-drip coffee brewer. Unlike hot coffee brewers that release acid during brewing, resulting in bitter-tasting coffee, cold brewers use ice water to extract a concentrated brew that maintains coffee’s natural flavor. Ice water in the 100-oz. glass sphere flows to a pair of nozzles with individual spigots that allow you to adjust the speed of the drip cycle from eight to 16 hours—the lower the speed, the stronger the coffee concentration. The top of each cylinder holds your preferred grounds and a replaceable cotton filter. The coffee can be refrigerated for up to one week and maintains its rich, bitter-free taste when heated in a microwave. Makes 90 oz. of coffee. Assembly required. 41" H x 11 3/4" W x 11 3/4" D.
