    Thanks for the link...

    I was only joking about using my ultrasonic bath but can see now that Frank was doing just that.

    Good on him for having a go.
    I might try is one day to see what it does to the coffee (hot/cold/whole bean?)

      Hi all

      Very interesting to watch the Kickstarter video and read the So Little Time article on sonicating coffee. Agree with Andy that they deserve praise for having a go at making coffee in different ways. Coffee is so complex that there are likely to be undiscovered methods to prepare "coffee". The later site is taking a scientific approach and trying to work out if its effective and produces better coffee but its a soft science approach. What I'd like to see is someone doing sonication of a coffee plunger with test subjects in a blind test.

      Hard to do a double blind test but I'd suggest at least someone in a kitchen makes the coffee and passes it to someone that does not know how it was made and they pass it to the test subjects. The sonicator even needs to be run while the non-sonicated coffee is made so test subjects don't get biased when hearing the sonicator. Better still would be for the sonicator and coffee making to be so separate from the test room that the subjects can't hear anything.

      I would also test both general public with a coffee tasting and experts using cupping and again using a blind test for both.

        Interestingly, I was wondering about cavitation for extracting coffee (especially for cold brewing), which lead to ultrasonics, which lead to a google search that turned up a few things (including this thread!).

        Firstly is this paper: Elixir Specialty Coffee, Made With Sound Waves, Is an Entirely New Kind of Caffeinated Beverage | L.A. Weekly

        Second is Elixir, apparently an Australian invention: Elixir Specialty Coffee, Made With Sound Waves, Is an Entirely New Kind of Caffeinated Beverage | L.A. Weekly

        I doubt I'll dabble with ultrasonics in the near future, but it's a promising alternative method for extracting coffee. It's a shame the Zappy Coffee Brew was yanked. Any idea what happened there?

        Cheers,

        Dan
