I mean, considering how many people in the world drink coffee, it could add up if this kind of method was widely implemented
Comment on I used sound waves to make espresso. It could cut coffee-brewing energy use by 75%

Is that something we really need to worry about?
More importantly, was the coffee better?

Maybe it also equalized the spread of fines. Someone get The Hoffman on the horn, we have a mission.

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.

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.
