Guinness

Guinness was a type of beer originating from Ireland in the 18th century. It was a dry stout, made distinctive primarily by the use of roasted barley.

A keg of Guinness was among the food stores aboard the USS Enterprise (NCC-1701), and was served during a reception welcoming Eremoid observer Verka in the 2250s. (SS ST (Conflicting Natures))

Carol Abramowitz and Gabriel Collins celebrated the completion of their Master's degree studies at Cambridge University with pints of Guinness.
