Anyone drinking Baby Guinness today warned against doing one thing on St Patrick’s Day

It's St Patrick's Day today (17 March) and people across the globe will no doubt be celebrating the special occasion.

While there are a million ways to commemorate St Patrick, the patron saint of Ireland, it's clear that what was once a religious holiday has become an international celebration of Ireland, its culture, and its history, with many choosing to pay tribute by toasting with Irish alcohol.

Guinness is a fan-favourite, but those not too keen on the stout may instead opt for a Baby Guinness, which isn't actually Guinness at all!

For those not in the know, a Baby Guinness is a shot made from Irish cream and coffee liqueur, deriving its name from the fact that it is made in such a way as to look like a tiny glass of the beloved tipple.

The agreed-upon go-to for the Irish cream liqueur is, of course, Baileys.

But anyone planning on making Baby Guinness shooters today has been issued a warning against doing one very specific thing.

Be sure not to throw any residual Baileys down your kitchen sink, as even small amounts of the stuff can seriously mess up your pipes.

Mike Flook, a plumber from MyBuilder.com, previously told the Irish Mirror: "Whilst it may seem that liquids like creamy drinks could be washed down the sink, the reality is that they can cause serious issues, especially if it's a repeated action.

"The result can be that, depending on the product and where you tipped it, you could face blocked toilets or sinks."

Mike also urged that cream liqueur drinks like Baileys can be a problem for your plumbing, outlining: "Whilst it may be delicious to drink, it doesn't keep for long, and might end up down the sink. However, this sort of beverage should never be disposed of in this way."

The expert explained that Baileys belongs to the 'FOG' category, which includes fats, oils and greases.

"Cream liqueurs have a large fat content, and as such fall into the category of FOG. FOG should never go down the sink, as it sticks to pipes and can cause blockages. It's also what's responsible for 'fatbergs' in our sewers," he warned.

"Half the population admit to pouring FOG down the drain, but don't be one of them. The problem with pouring leftover fat down the drain is that it will cool, which can lead to blockages and fatbergs in your pipes."
