‘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.

    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. massive ultrasonic schlong submerged in a beaker with coffee
