‘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.
Just as good is subjective, the question is, is there a noticeable difference? If there is, that difference could mean everything to serious coffee snobs.
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.
Ah so I take it this is likely a replacement for the current process they use to make instant coffee. Which I know is usually brewed in industrial sized percolators. If that’s the case I definitely think it would improve the favor.
I’ve tried it at home and it was neither especially fast nor good. Cool brew is better. It really didn’t have much to do with espresso. Maybe my setup sucked. Maybe I should try again, has been a while.
You get a lot more suspended particles rather than a clean extract which isn’t super appealing.
I don’t have this thing at home, just some submergible ultrasonic thing from AliExpress.
