Inside a Guinness surger unit.

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.
