‘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.
Definitely a unique approach to coffee making. I was thinking how you do generally want coffee to either be cold or hot, room temperature is the one temperature that just doesn’t work.
Looks legit, especially for cold brews.
