11. Responsible for Popularizing Nitrogenated Draught Beer
In 1959, Guinness revolutionized the beer industry by developing the draught keg system, leading to the creamy, nitrogen-infused head iconic to Guinness stouts. This innovation was spearheaded by Michael Ash, a mathematician turned brewer, who discovered that blending nitrogen with carbon dioxide created smaller bubbles, resulting in a smoother, creamier beer. This advancement set Guinness apart and became a defining characteristic of their draught beer (en.wikipedia.org).
