Well, they apparently had already used ultrasound to speed up the cold brew process. This was a continuation of that research.

According to the article this is aimed at the commercial/industrial level brewers to save energy. So the coffee snobs probably aren’t really going to be a target audience. Though if it becomes at all widespread I’m sure people will give it a try. There aren’t a shortage of people trying all sorts of wild ways to brew out there.

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.
