‘Ultrasonic espresso’ made with cold water and high-frequency sound waves uses less energy than the traditional version – and taste tests show it’s just as good.
According the the article, the espresso was rated equal to traditionally brewed. Ultrasound brewed filter coffee was rated as better than traditional.
Though it sounds like they were all cooled down since the ultrasonic brewing didn’t best the water. So that is also a factor. If you like hot coffee, this wouldn’t be a worthwhile brewing method.
Is that something we really need to worry about?
More importantly, was the coffee better?

Maybe a more effective cold brew then
Well, they apparently had already used ultrasound to speed up the cold brew process. This was a continuation of that research.
I mean, considering how many people in the world drink coffee, it could add up if this kind of method was widely implemented
Maybe it also equalized the spread of fines. Someone get The Hoffman on the horn, we have a mission.
