A new way to brew and experience coffee
Coffee contains a vast spectrum of flavor and aroma compounds that come to life through brewing. We sought to capture the widest range of these compounds through a rethinking of how coffee is extracted at a physics level, while keeping the best parts of the traditional espresso UX. The new Osma Pro is the result.
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.
Osma uses acoustic cavitation to cold-extract the widest range of flavor and aroma compounds, yielding a bracing and complex cup with espresso-like crema and mouthfeel, with higher extraction yield in two minutes than traditional cold brew can achieve in 24 hours.
Core technology
Osma brews up to 8oz of ice cold coffee to 20%+ extraction yield in less than a minute.
Along with up to 12 bar of pressure, our fundamental mechanism of action is acoustic cavitation.
Acoustic Cavitation
Our diaphragm pump is optimized to deliver oscillating water pressure to the coffee in the portafilter.
This sinusoidal pressure oscillation causes bubble nuclei in the coffee and water to expand and contract in sync with the pump's frequency.
The bubble nuclei grow towards their resonant size as they expand and contract, and the oscillating bubble boundaries exert shearing forces against the ground coffee bean particles.
This shearing extracts the coffee and forms a tenacious, microbubble-based texture and crema.
