Guinness as a brewery and beer brand traces its origin to the year 1759 , when Arthur Guinness began brewing at St. James’s Gate Brewery in Dublin, Ireland.

Core fact: “Invention” of Guinness

  • In 1759 Arthur Guinness signed a long-term lease on the St. James’s Gate Brewery in Dublin and started brewing ales there; this date is treated as the founding of Guinness.
  • Guinness later focused on dark porter-style beer (the ancestor of the modern stout) from the late 18th century, but the company’s own history and most references mark 1759 as when Guinness was effectively “invented” as a brewing enterprise.
