Always complaining that your pint of the black stuff is never as good as that black nectar you supped in Ireland? Well, celebrate this St. Patrick’s Day in true Irish tradition with the Guinness Surger Starter Kit.

The Surger Kit is a revolutionary system that uses ultrasonic waves to stimulate the molecules in your pint of stout so your sad can of Guinness is transformed into a cream-brimmed glass of velvet. So, how does it work? Well, refrigerate a can of Guinness for at least three hours. Pour a little water onto the tray at the top of the Surger unit. Next, pour your can of Guinness into a glass at a 45 degree angle. Now, place you glass of freshly-poured Guinness onto the tray of water on the Surger unit. All that’s left is to hit the button on Surger unit. Sit back and witness the miracle of ultrasonic waves. In a matter of minutes, you can enjoy a Guinness just as good as the fresh draught served at The Storehouse in James’ Gate.

The Guinness Surger Starter Kit contains a Guinness-branded pint glass, 2 cans of Guinness Draught Surger and the Surger unit. The kit retails at £16.99 and is available from participating Tesco Extra stores across the UK.
