I agree this is the kind of thing I should find on YouTube, not in an academic journal. But the paper does go into a lot of detail about extraction efficiency, so I guess there might be some useful measurements.
I am curious about the taste. It should be somewhere in between cold brew and hot, but probably closer to cold. Cavitation is a violent process. On a micro scale itâs literally boiling. Then the steam bubble collapses and is instantly cooled because of an almost infinitely big heat sink. So when cavitation occurs near the coffee grounds, some of the extraction would be at much warmer temperatures, for a brief instant.
Oh, yes, I was making fun of the headline, about inventing.
With that in mind basically any experiment/measurement/scientific theory is some sort of invention, itâs just that we dont call it that.
Like, nobody invented the concept of tank, ppl âinventedâ materials, equipment, manufacturing & logistics/admin processes, etc that at one point allowed for a feasible âtankâ to be compiled.

Yeah, they didnât even invent it. One company basically tried to do the same brewing technique commercially, but I guess they didnât get the word out in time: https://www.engadget.com/osma-pro-cold-brew-coffee-machine-review-131552500.html
You can buy sub 50 moneys liion battery operated lil machines ⊠that donât use âsound pressureâ but âair pressureâ to brew (lul).
