Enjoy a cup of tasty cold brew coffee anytime you like with the Osma Pro countertop brewer. This coffee accessory uses microcavitation to preserve coffee’s heat- and time-sensitive compounds. This relies on 3 overlapping processes: recirculation, pressure, and harmonics. This results in a drink with a wide range of flavor and aroma compounds with an espresso-like crema. Best of all, it happens in only 2 minutes. In fact, this coffee maker can brew up to 12 oz. at a time and is easy to use. Just grind your coffee, load it into the portafilter, and fill a tumbler with around 8 oz. of ice water. Place the tumbler on the Osma Pro countertop brewer and press start. The diaphragm pump sucks the ice water from the cup and forces it through the coffee. Then the coffee falls back into the cup. You’ve never made cold brew so quickly.
