King Charles poured the “perfect” pint as he celebrated the opening of the new Guinness brewery in London yesterday morning. Enthusiastically going behind the bar to learn how to pour a pint of the world-famous Irish dry stout, the King quickly mastered the art of pouring a pint of Guinness into one of its trademark glasses featuring the harp logo.

The audience applauded as the King poured an “absolutely perfect” pint of stout, having been told to hold the glass at a 45 degree angle while pouring, filling it to three-quarters full and letting it settle before topping it up just above the rim. Charles brushed off the congratulations and simply said: “If you say so!”

Leo Ravina, 23, had the honour of talking the King through the process and remarked the King’s pour was “absolutely gorgeous” and said “you’ve done this before I see”. As he took a sip of the pint, the King ended up wearing a white moustache as the creamy white froth left an imprint on his upper lip.
