NPR had an interesting article on the use of cavitation in the food, and beverage industries including brewing.. Pretty cool. https://www.npr.org/sections/thesal...ses-cavitation-the-oceans-most-powerful-punch Anyone want to take a crack at a diy homebrew system?
Witches Hat brewing is not far, and I know Ryan Cottongim. The use of this for hop extraction has been covered a few times in articles. Not sure how much it has caught on.
A web search will get you many articles. I went a little farther and found the first one I read, in a local beer publication. http://digital.zoompubs.com/publication/?i=240423&article_id=1894997&view=articleBrowser&ver=html5#{"issue_id":240423,"view":"articleBrowser","article_id":"1894997"}
