It’s that time of the year again, but you bought too much eggnog for the family this time. You’re probably worried about how long you can hold onto it and ask yourself: Does eggnog go bad? How long does it last?
Here’s the deal: Store-bought eggnog, when unopened, can last between 2-3 days past the sell-by date. As soon as you open the packaging, it will last about five days.
Signs Eggnog Has Spoiled

When inspecting whether your eggnog is still fresh, the first thing to check is the smell of your eggnog. If it gives off a sour smell, it’s time to toss it out.
Have a look at the appearance of your eggnog. If the color has changed or the texture has become lumpy, then you should get rid of the eggnog.
If there are no signs of spoilage, give your eggnog a taste to make sure it is still okay. If you’re happy with the quality, then you can hold onto it.
Finally, if you have stored your eggnog for more than a week, it’s best to discard it.
How To Store Eggnog
Starting with homemade eggnog, make sure it has cooled down before storing. Once it has cooled down, transfer it to an airtight container, seal it tightly and store it in the fridge.
Store-bought eggnog should be sealed tightly and stored in the fridge.
Make sure to place your eggnog in the far corner of your fridge, as this is where fewer temperature fluctuations happen.
Can You Freeze Eggnog?

Eggnog can be frozen; however, the thawing will result in lumps and separation. You probably won’t want to drink thawed eggnog, but it can be used in baked dishes.
When it comes to freezing eggnog, think about how you plan on using the eggnog first. Using an ice cube tray to freeze your eggnog into smaller portions is ideal if you’re using it as a creamer. If you’re using it in recipes, freeze your eggnog in an airtight container. Leave some room in the container as the liquid will expand.
Defrost your eggnog in the fridge overnight. You can refreeze the leftover eggnog once done.
How Long Does Eggnog Last?
Homemade eggnog, without preservatives, only lasts between 2-3 days in the fridge. Store-bought eggnog lasts longer because it has been pasteurized.
When it is unopened, use it 2-3 days past the sell-by date. As soon as you open the packaging, it will last five days in the fridge.
Leftover Uses Of Eggnog

If you have some eggnog left over, try adding it to these dishes. A mashed sweet potato dish goes well with a splash of eggnog. Eggnog can be added to oatmeal in place of water. Froth your eggnog with a blender or mason jar, and add it on top of your lattes. Eggnog can be used instead of heavy cream or milk to make extra-sweet biscuits.
The Verdict
Eggnog has some health benefits. It contains potassium, calcium, vitamin B12, vitamin A, phosphorus, and iron.
This is thanks to the eggs and dairy-based products used to make eggnog. The eggs are a source of protein, and the spices added, such as nutmeg, can be anti-inflammatory.
Eggnog’s shelf-life is not long. It will retain its freshness for 2-3 days if homemade and five days if store-bought.
Always be on the lookout for signs that it has gone bad. This includes the presence of a sour smell, lumpy texture, and an off taste. If you find any of these in your eggnog, discard it.
