New way of making espresso with ultrasound

The crema looks like terrible, more like Nespresso, and having the coffee warm is kinda important.

But perhaps this can be used in the instant coffee industry or something.

Not even the baristas are safe. Technology really is coming for everyone.

75% energy save to make a room temperature expresso. I am ok spending a bit more energy to have it warm.

Someone get James Hoffmann on the line right now.
