Guinness is probably the most popular stout in the world and even when it’s mentioned a connection to Ireland is automatically assumed by anyone. Although Guinness is so popular its really does take an acquired taste for anyone to drink a full pint of the black stuff. Its a heavy drink with its thick head and dark liquid. For those who drink several pints in one sitting only knows too well what the day after will bring and we are not just referring to the hangover. It was first brewed in the 18th century by Arthur Guinness.
