It's the day when everyone suddenly claims to have some distant Irish relation.
Yes, St Patrick's Day is upon us, and if you're celebrating the holiday (Irish or otherwise) you're probably going to be consuming a fair amount of Guinness.
In the above video, Arron Ridgeway from Guinness Storehouse in Dublin demonstrates how to pour the perfect pint.
Try out his tips to impress your mates, or watch your local barman carefully to see if their skills match up.
Step 1: Find The Perfect Glass
Ideally you want a tulip-shaped pint glass (like the official Guinness one) that is nice and cold to pour your pint into.
Step 2: Get The Right Angle
Like with most beers, you want to pour Guinness at a 45° angle. If you have a Guinness branded glass, place the harp directly under the nozzle as a guide.
Step 3: Pour Like A Pro
Pull the tap all the way towards you to get the maximum amount of pressure. This will liberate the necessary amount of gas need to give your pint a decent head.
Step 4: Level The Glass
As the Guinness reaches the 'Guinness' wording begin to level the glass, slowly increasing the angle you're holding it at until you're holding it straight.
Step 5: Leave The Beer To Rest
Do nothing for 60 seconds and watch your pint change colour. It takes a little patience, but it's necessary.
Step 6: Top It Off
Push the glass away from the nozzle as you fill your pint to the top for the perfect finish.
Step 7: Enjoy
Kick back with your pint and have an awesome St Paddy's Day!
