A Californian bar has poured what is sure to be confirmed as the world’s largest pint of Guinness.

A crowd of 400 people gathered in the Auld Dubliner Irish Bar’s patio in Tustin, California recently to watch the mammoth 900-lb. glass, made of shatter-resistant acrylic, being filled with 2,772 lbs. of beer. Though it has yet to be certified, the feat should earn the bar a place in the Guinness Book of World Records for world’s largest glass of beer.

Though it hasn’t been confirmed by the bar, rumor has it that it was ordered by a very thirsty Irishman who was willing to wait for it to be poured using the traditional 2-part pour….Impressive.
