Guinness coaster

Guinness is a world-renowned Irish dry stout that originated in the brewery of Arthur Guinness at St. James's Gate, Dublin, Ireland, in 1759. Over the centuries, it has become one of the most successful alcohol brands worldwide, known for its distinct dark color and creamy head. The brand's identity is closely tied to its Irish heritage, often using the traditional harp symbol as its logo, as seen on the coaster in the image.

Today, Guinness is owned by Diageo, a British multinational alcoholic beverages company headquartered in London. Diageo was formed in 1997 through the merger of Guinness PLC and Grand Metropolitan. While the core beer product is still brewed at St. James's Gate in Dublin for the European and North American markets, Guinness is also brewed under license in dozens of countries worldwide, particularly in Africa and Southeast Asia. Branded merchandise like coasters are typically produced by various licensed third-party manufacturers globally. In South Korea, Guinness products are distributed through Diageo Korea.
