But if you thought things couldn't get any better, hold the phone, because you can now get a FREE pint of the black stuff.
Cashback site TopCashback is offering all new customers the chance to pick up a glass from any UK store or pub - you just have to order a pint, take a picture of the receipt and voila, you can claim all your money back.
But with the offer only lasting until midnight on St Patrick's Day itself - 17 March for those who don't know - you'll have to get a move on if you want to take advantage of it.

There is a limit on how much you can claim back though, with a max claim of £5 you will have to settle for using your own money to pay for anything more than that. But let's face it, if you're paying more than £5 for a Guinness you're being robbed.
So how does it work?
Firstly you need to sign up to TopCashback, then spend up to £5 on your pint. Next you have to take a photo of your receipt to show that you have actually used the money to buy a drink, then submit it to the company's site.
And that's it, once you've sent the photo your account will be checked and the money should be back in your account within 30 days.
Whatever you do though, don't be like this guy who ordered a pretty disgusting Guinness cocktail, last year.
Ross Maghielse, who works for the Philadelphia Inquirer, was enjoying a quiet drink in a sports bar in Seattle, when he spotted someone order a Guinness and Sprite. Yes, that's Guinness - an Irish stout - and Sprite - a cool, refreshing lemonade.
Both of those things are great on their own, but together they form an unholy cocktail that looks like somebody has poisoned the water supply.
If you do want to claim the offer and enjoy a regular Guinness however, there are a few conditions - such as the obvious, you must be over 18.
Also, if you live in Scotland then we have some bad news, as the offer isn't available north of the boarder - sorry.
