Their method appears to be sound

This idea existed as a product for a few years. It was called the Osma Pro and worked pretty well, although the learning curve was steep. It used a pump to create the acoustic cavitation which seems a bit different than the technique being used here. But the outcome is the same...super quick coldbrew extracted via acoustic cavitation. Sadly the company totally disappeared and left customers to fend for themselves when issues popped up. Guessing there are only a handful of people left still using the machine. Hopefully this research opens the door for a bunch of commercial applications! Would be great to see the tech widely adopted

Thats a cool new concept. I've been doing this for years. I started when i was in Afghanistan by making a mixture of grounds and water, and using a few of those "turn your sink into a dishwasher" transducers. Worked great, filtering took longer.

My wife has already ordered me to obtain one for her as soon as one becomes available.

Ive been doing this for almost 20 years. First regular espresso, then cold, then another Ultrasonic cold method that produces a cold brew with heavy "milk" like texture and body. So not new, but this technology is expensive to scale, at least in my designs. here is a old video from my other channel kzbin.info/www/bejne/eqDUmpyFnbCmnqM&ab_channel=jepyraco

Wait, you can get a naturally warm cold brew without reheating it. A normal brew but it extracts like a cold brew in minutes. That's is simply a new type of coffee.

Depends on coffee. If u have a cheap dry heavy preroasted coffee its done with one hour. While others take longer.

What about the possible free radicals increase and antioxidants decrease in this process?

Time to bond a piezoelectric ultrasonic generator into the grouphead of a slightly broken espresso machine.

I do this with my ultrasonic jewelry cleaner.

I thought about using it as well. Did you already try it, how's the taste?

Keurig K-Iced Single Serve Coffee Maker has a brew over ice button, it makes iced coffee in 2 minutes

Yes, but that is not the same by any means. Temperature plays a huge role in what compounds are extracted from the coffee, which is again why cold brew is so much different from hot brewed coffee over ice. In fact, I’m not even convinced this solution is a true replacement for long steeped cold brew, because the time of exposure to water also is a key factor that enhances some really great flavors in some cold brews. Here they’re substituting time with agitation and surface area exposure, which may be similar, but I guarantee it will not be a replacement.
