Originated in the brewery of Arthur Guinness (1725-1803) at St. James's Gate, Dublin. Guinness is directly descended from the porter style that originated in early 18th-century London.
Irish stout or dry stout is very dark or rich in colour and it often has a "toast" or coffee-like taste.

Arthur Guinness started brewing ales from 1759 at the St. James's Gate Brewery, Dublin. On 31 December 1759 he signed (up to) a 9,000 year lease at £45 per annum for the unused brewery. Ten years later on 19 May 1769 Guinness exported his ale for the first time, when six and a half barrels were shipped to Great Britain
