Have we been pouring “pints of the dark stuff” incorrectly all this time? The science sippers at Tech Insider demonstrate how Guinness may have been attaching the wrong glassware to their brew from the start. But honestly, can an oversized martini vessel be more appropriate than the suggested tulip glass, the one that’s custom made to make the bubbles slowly descend?

Ordering a Guinness on drafts takes longer than most other beers. Part of the reason is the gas used to carbonate it: nitrogen. William Lee, a professor of Industrial Mathematics at the University of Huddersfield, discovered that the specially-designed Guinness pint glass causes the bubbles to sink. This increases the wait time for the beer to settle. From his findings in the study funded by the Science Foundation Ireland, Lee believes something closer to a giant martini glass would work better.
