Guinness is a popular dark Irish beer in the UK. It's best to drink it in Ireland as it doesn't seem to travel well. The main characteristic is the very fine bubbles that almost seem to flow downwards when it is poured, and create a distinct drinking experience with a characteristic striking contrast between the black liquid and white head of foam on top.
One way that Guinness have tried to make the drink more transportable is to ship it in cans to be served in glasses that are then "surged" on an ultrasonic mat. This causes intense micro-cavitation in the liquid giving the correct texture to the beer as opposed to the coarser effect of carbonation alone. It works well.
This also ensures the Guinness is very predictable with no storage and piping issues in bars that can't accommodate a proper dispensing system.
The surger is also available for home use with the specific cans of the beer. I'd guess it also has other uses where a burst of ultrasonic energy is required.
Note that these units do require a small amount of water in the base to couple the ultrasonic energy into the glass.

    Does it make mist?

    Do not use C02 based drinks in the Surger unit. This can only be used on Beers that are fizzed up with Nitrogen and if you use it on a c02 drink it will go everywhere. You can get special surger cans of the nitro guiness OR you can get the normal draught cans and put a tiny hole in it to stop the widget from firing. Then put it in the surger unit but NEVER co2

    Never heard of these, only cans with the widget thingy. Must be an Australian thing.
    I am however wondering what might happen if that monster cap would somehow be removed and soldered back with the polarity reversed. Got to be slightly more spectacular than the little USB power supply that I saw Clive blow apart recently.
    FOR SCIENTIFIC CURIOSITY!!

    Maybe a sub playlist could be added to "Will it carbonate?" I'd definitely be interested to see how you go with carbonated AND surged Jägermeister and Vodka

    FOR EVEN MORE SCIENTIFIC CURIOSITY!!

    I actually use it sometimes for my Guinness foreign extra. Just half fill the pint glass and surge it then top it up.

    Hi, I hope you don’t mind me reaching out to you .. I have one of these that isn’t working, it lights up but nothing happens when the button is pressed, it worked when I got it after it being powered on for a few hours… Ive a degree in electronics but that’s going years back now .. any help appreciated to what to look out for when I break out the multimeter … thanks

    I was told some years back that if your Guiness was dispensed properly you should be able to write your name in the foam… 🙂
