A pint of Guinness, please!

Guinness is one of the most famous worldwide beers. It was developed in St James brewery, Dublin, by Arthur Guinness in 1759.
The most distinctive feature of the product is the burnt flavor that is derived from roasted unmalted barley.
Guinness is identifiable as the soul of a nation. Guinness in Ireland is an institution in its own right, symbolizing the Irish people.
Guinness stout is made from water (taken only from Wicklow Mountains in the North East of Dublin), barley, roast malt extract, hops, brewer’s yeast and also involves the use of isinglass made from fish. That is the reason why vegan people could not drink this kind of beer.
The perfect pint is the product of a double pour which, the according to the company, should take 119.5 seconds. That is the reason that slogan says: “Good things come to those who wait”. The brewer recommends that draught Guinness should be served at 6 °C. To begin the pour, the server holds the glass at a 45 angle below the tap and fills the glass three quarters full, creating friction and forcing the creation of small nitrogen bubbles which form a creamy head. After allowing the initial pour to settle, the server fills the remainder of the glass until the head forms a slight dome over the topo of the glass.
Some curiosities are:
• A pint of “the good stuff” contains only 198 calories. That’s less than most light beers, wine, orange juice or even low fat milk.
• On September 24, 2009 at 5.50 (or 17.59 in the 24 hour clock) Ireland and the world celebrated 250 years of Guinness with “Arthur’s Day”. In almost every country across the globe merry makers raised their glasses and cheered “To Arthur”.
• Though Guinness is now officially on the record as denying this claim, some research does support that Guinness is good for your heart. It was not so long ago in Ireland that pregnant women were told to drink a glass of Guinness every day to fortify themselves and their baby.
