Osma’s high-tech instant cold brew could change summertime coffee forever

Osma is the latest project from designer Joey Roth, who evolved from high-concept speaker tech to tea and coffee tech, and now has found a way to integrate these two disparate pursuits with a unique vibratory method of extraction. And although Roth has had several successes over the years, this could be his most valuable yet.

To see why, it helps to understand the way coffee is ordinarily made, which generally comes down to one of two things: soaking the grounds in hot water, or forcing it through the grounds under pressure.
