The widget-less Surger is designed for use with an electrical device that emits ultrasonic waves to agitate dissolved nitrogen in the beer after it is poured. Available for home use in the UK, Surger units and cans are distributed exclusively to bars and restaurants in North America. “We’ve got a lot of great feedback on the theater of the Surger,” says Patrick Hughes, Guinness brand director at Diageo North America in New York, “but making sure it’s executed properly is a challenge.” Training and, “a little bit of TLC,” have been necessary when placing the device in pubs too small to accommodate a traditional keg-and-tap system.
Changes in draught cans also are being made, with bolder graphics and a larger Brian Boru harp, according to Hughes. Functional changes, including a larger opening for a smoother pour and creamier head, are also included.
