It’s rare that a truly new way to make coffee is invented, and nearly all of them have one thing in common: heat. After all, it’s hot water that quickly extracts flavor and body from grounds. But Osma, a new device using an entirely novel coffeemaking technique, makes a rich, strong espresso-like drink at any temperature, including icy cold — and it might be the next big thing in the industry.
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.

In the first case, which includes drip and pourover, French press, and others, the heat of the water passively frees the oils and volatiles from the ground beans …read more
