Real motive for why there’s a ‘ping pong ball’ in Guinness cans lastly defined

It’s St Patrick’s Day and that means people will be drinking plenty of Guinness but if you’re treating yourself to a stout out the can then you might wonder what’s at the bottom of it

Guinness lovers, ever wondered what gives your favourite pint that iconic white creamy head? Well, there’s a secret inedible ingredient that’s responsible for that luscious froth.

Sure, cracking open a can of Guinness at home might not quite match the experience of a fresh pour at the pub, but it still hits the spot when you’re lounging on the sofa.

Ever been puzzled by the rattling sound from an empty Guinness can and pondered over the mystery of its foamy top? Hold tight, because we’re about to enlighten you.

For the Guinness aficionados out there, the presence of a white plastic ball inside the can is old news.

However, for those new to the world of stout, discovering a ‘ping pong’ ball at the bottom of their drink might be quite the revelation.

So, what’s this mysterious plastic ball called, and what does it do?

These too-big-to-escape widgets are the magic behind Guinness’s rich and velvety texture, setting it apart from other stouts in the market. The technique known as ‘nitrogenisation’ is the “answer”, says the official Guinness website.

In pubs, the unique texture and taste of Guinness are achieved by combining nitrogen gas and carbon dioxide during the pouring process. This technique gives the drink its distinctive look and flavour.

The widget, filled with nitrogen, mimics the pub experience for Guinness enthusiasts at home. As soon as the can is opened, the widget releases a “magic surge of bubbles”, allowing customers to enjoy the stout’s authentic taste from the comfort of their own homes.

According to Guinness’ website, the widget even ‘outdid the internet’, with a survey of nearly 9,000 people voting it as a more significant invention than the internet itself.

In 2023, Guinness introduced the ‘nitrosurge’, a device that can be attached to specific cans to further enhance the at-home pouring experience. Given the passion people have for the appearance and taste of their Guinness, it’s no surprise that the widget is so adored!
