Genius Math Professor Demonstrates Why Everyone Has Been Pouring Guinness Wrong

Mind. Blown.

Tech Insider Video

There’s nothing like a nice tall Guinness, with its rich dark body and fluffy foam cap. But believe it or not, an industrial math professor from the University of Huddersfield in the UK has apparently proven everyone has been pouring our favorite dark lager wrong all along.

The Tech Insider video above backs up Professor William Lee’s contention that we could have a perfect draft of Guinness every time—as long as the bartender doesn’t use the glass that Guinness prefers. 

To break it down: Guinness is carbonated with nitrogen, and it’s usually poured in the Guinness-designed tulip glass. The design of the tulip glass, Lee says, forces nitrogen bubbles to sink.

If you sit and just look at your Guinness first, you’ll see that slow descent of bubbles from the surface into the depths of the beer. The more you drink Guinness, the more interesting that becomes, but who wouldn’t want a truly frosty-looking perfect pour instead. 

Professor Lee says we should have our Guinness in a giant martini glass instead.

If you are a little self-conscious about how you handle yourself at the bar, this may be a non-starter. Let’s face it—to some, this is going to feel kind of silly. But you know, that clean line between foam and the good stuff beneath it might be worth a shot, at least once.

Just don’t try it in an out-of-the-way Dublin pub. Something tells us that might get you a little more attention than you’d like.
