What is Osma?

Osma makes a cold brew coffee machine that uses microcavitation technology to extract a full-bodied and balanced cup of coffee.

In their own words

Osma brews up to 12oz of ice cold coffee to 20%+ extraction yield in under two minutes using harmonics, recirculation, and microcavitation. Machined, assembled, and tested one at a time at our Oregon workshop, each Osma is numbered as part of our 1000 piece first edition. Use your favorite coffee and E61 portafilter.
