The best-known of Irish beers, Guinness has taken the world by storm since its inception in the 1770s. It is now brewed in 49 countries and sold in more than 150, and it’s hard to go anywhere without seeing Guinness on tap. And it’s all due to Arthur Guinness, the original brewer, whose porter recipe took off. According to Guinness, Arthur Guinness originally brewed ale and only started making porter in the 1770s due to some competition from other brewers.​ The Guinness Extra Stout has an unmistakable deep-dark colour with a crisp hint of roasted barley, a breeze of hops and a refreshing bite​ while the Guinness Draught is smooth, very creamy and slightly heavier.

Guinness was one of the first trademark-protected products ever. According to the brewery, the company came up with a trademark label in the 19th century to “protect the Guinness name” overseas. That includes the harp on the label and the signature of Arthur Guinness

The brewery is also behind the Guinness Book of World Records. In 1954, the head of Guinness, Hugh Beaver, got into an angry fight with someone and decided to assign an official reference guide to solve all disputes. It was originally a promotional item Guinness gave to bars who stocked the Guinness brew!
