How Long Does Irish Cream Liqueur Last?
Opened Irish cream liqueur is best within 6 months, kept in the fridge or a cool cupboard. Unopened bottles keep about 2 years from the date they were made. Homemade Irish cream lasts only 1–2 weeks in the fridge.

Irish cream is a blend of Irish whiskey, fresh dairy cream, sugar and flavorings, bottled at around 17% alcohol. The alcohol and commercial homogenization preserve the cream far longer than you would expect of a dairy product, but not forever: with age and heat the cream fats eventually separate and the liqueur curdles and sours.
How to store irish cream liqueur
- Keep the bottle away from direct sunlight and heat sources; temperature swings are what cause the cream to separate early.
- Wipe the neck and threads of the bottle after pouring. Dried, sugary cream residue around the cap is the first place spoilage starts.
- Do not store it in the freezer. The cream can separate and turn grainy, and the low alcohol content means it may partially freeze.
- Write the opening date on the label, since a bottle that only comes out over the holidays is easily older than you think.
How to tell if irish cream liqueur has gone bad
- Curdled lumps, a thick, sludgy or stringy pour, or clots left on the glass.
- A sour, rancid or stale-dairy smell instead of sweet whiskey and chocolate.
- Separation into a watery layer and a fatty layer that does not mix back in when shaken.
- A noticeably darker color, or a sour or bitter taste.
Bacteria that cause food poisoning usually do not change the look, smell or taste of food. Go by the time limits first, and the signs above second.

Frequently asked questions
Does Irish cream need to be refrigerated after opening?
The major producers say it does not have to be, as long as it is stored below about 77°F (25°C) and out of the sun, because the alcohol preserves the cream. Refrigeration is still the more cautious choice, especially in a warm house, and the liqueur is usually served chilled anyway.
Can Irish cream go bad and make you sick?
Yes, it can spoil, because it contains real dairy cream. Old Irish cream curdles and turns sour, and drinking it can upset your stomach. Pour a little into a glass first if the bottle is old: if it is lumpy, separated or smells off, discard it. Do not rely on taste alone.
Why did my Irish cream curdle in my drink?
Acid is the usual cause. Mixing Irish cream with citrus juice, tonic water, cola or acidic wine makes the cream proteins clump, just as lemon juice curdles milk. It can happen with a perfectly fresh bottle and is not a sign of spoilage. Pair it with coffee, other spirits or milk instead.
How long does homemade Irish cream last?
Plan on 1–2 weeks in the fridge, in a sealed bottle. Homemade versions use fresh cream and often sweetened condensed milk, without the homogenization and stabilizers of commercial products, so they are limited by the cream. Recipes that include raw egg should be avoided or made with pasteurized eggs and used within a few days.
