This co-hosted podcast episode delves into the history and mechanics of the Guinness widget, a small plastic sphere inside cans of Guinness beer. The hosts discuss the widget's role in replicating the creamy texture of cask-poured Guinness, explaining how it works by releasing nitrogen to create a smoother, less carbonated pour. They trace the invention back to Michael Ash and John Lunn, highlighting the challenges of incorporating nitrogen into canned beer. A key takeaway is that the widget isn't pre-filled with nitrogen but rather fills during the canning process, creating a mini "beer jet" effect upon opening. The discussion also touches upon the differences between bottled and canned Guinness and other nitrogenated beers.
