The traditional colour associated with St. Patrick was blue until the turn of 19th century.
Two letters written in Latin by St. Patrick in the fifth century still exist.
No snakes have ever lived in Ireland, as the surrounding seas are too cold for them to migrate.
There is no such plant as a shamrock – the three-leafed plants worn on St. Patrick's Day are generally clover or wood sorrel.
In the early 20th century a law was passed that pubs in Ireland had to be closed on St. Patrick's Day. This law was only repealed in the 1970s.
All the commercially available Irish whiskey on the market today is made at just three distilleries: Bushmills, Midleton & Cooley.
Bushmills is the only working distillery in Northern Ireland.
It's a myth that all Irish whiskey is triple-distilled: Cooley's single malts are all double-distilled.
The only style of whiskey that is unique to Ireland is single pot still whiskey, which is made with a mixture of malted and unmalted barley.
Although Midleton produces tens of millions of litres of grain whiskey every year for Jameson, the only commercially available Irish single grain whiskey is Greenore, from Cooley.
40ml Irish whiskey
(we recommend Bushmills Black Bush)
Freshly brewed coffee
1 tsp brown sugar
Whip the cream to a thick, but pourable, consistency, then refrigerate.
Pour the whiskey into a tall, thick-walled glass (ideally with a handle or a thick stem).
Top up with freshly-brewed coffee to an inch below the top of the glass.
Stir in the sugar – this helps the cream to float.
Gently pour the cream over the back of a spoon onto the top of the drink.
50ml Irish Whiskey
(we recommend Jameson Select Reserve)
Pour the whiskey into a tall tumbler glass filled with ice.
Top up with the ginger ale.
Garnish with a large slice of lime.
40ml Irish Whiskey
(we recommend Powers Gold Label)
1 tsp honey
Pour the whiskey into a tall, thick-walled glass (ideally with a handle).
Top up with hot (not boiling) water and stir in the teaspoon of honey.
Garnish with a large slice of lemon, studded with cloves. Cinnamon sticks are another popular garnish.
