The Osma Cold Brew Coffee Maker advances how coffee is extracted at a physics level, while keeping the best parts of the traditional espresso user experience.

Traditional cold brew captures heat-sensitive compounds that hot water destroys, but its 12+ hour brew loses time-sensitive compounds. Hot brew methods capture the time-sensitive volatile compounds that give coffee its crisp, bright notes and convey freshness, but destroy the long tail of heat-sensitive compounds before they can be experienced.

The Osma Cold Brew Coffee Maker brews up to 12oz of ice cold coffee to 20%+ extraction yield in under two minutes. Our fundamental mechanism of action is microcavitation: thousands of microbubbles forming from the release of co2 trapped in the ground coffee beans, then collapsing within the portafilter, dumping the energy required to extract the widest range of flavor and aroma compounds.
