The magic of the widget

The story of
Guinness Draught in a can

What’s the secret to making a beer that’s rich and creamy with a smooth, velvety texture? The answer is nitrogenisation; Guinness’ skilful pairing of nitrogen gas and carbon dioxide to create a perfectly balanced stout. In fact the result is so good we even use this on our latest beers like Nitro IPA.

But how do you use a technology that was originally designed to allow the beer to be poured in pubs on draught, to deliver the perfect Guinness serve in a can? That’s where those little white balls that you find floating in your can come in.

The world famous Guinness widget uses an ingenious nitrogen filled capsule that surges with bubbles when the ring pull is opened – replicating the draught experience in a can.

The result? A perfectly smooth beer that’s unmistakably Guinness.
