How Long Does Grenadine Last? Does it Go Bad?

People buy grenadine to make cocktails and drinks.

Once they make drinks from it, the leftovers rest in the fridge for a while.

But after this long storage period, they get confused about whether the beverage is safe to drink or do grenadine go bad.

Grenadine contains a lot of sugar, just like other syrups, which makes its shelf life quite long.

However, one should check whether the beverage is still good, as bad grenadine might cause any sick.

Bad grenadine will make your cocktail taste bad too.

Thus, avoiding using the beverage to make a cocktail will be better.

How Long Does Grenadine Last? Does Grenadine Go Bad?

Grenadine is a non-alcoholic syrup, which means it will not serve you for an indefinite life but for how long you can use it.

This syrup comes with the best date; do not confuse yourself with these two words.

The best-by date is a quality indicator provided by the manufacturer as it describes the period until the syrup offers its quality at its peak.

The syrup is fine to have after the best-by date, but one had to taste low-quality grenadine.

On the other hand, people are advised to refrain from consuming this if it has crossed its shelf life.

When you have an unopened bottle of grenadine, it can be stored in the pantry for one year.

Unopened bottles stored at room temperature are more secure; thus, avoid putting them in the fridge.

Once the syrup bottles are opened, keep in mind that their shelf life will decrease faster.

This is because when the lid is opened, the syrup gets in contact with bacteria, making their life smaller.

Thus one can only store opened grenadine for one to two months at room temperature.

If you want the syrup to last longer, then you need to store it in the fridge.

There it can be kept for four to six months, and you can also retain its quality.

How To Tell If Grenadine Have Gone Bad?

  • Check Consistency

When you are trying to decide whether it is good or not, you can check the consistency of the syrup.

This is a good method to find bad syrup as you just need to inspect its consistency; if it’s thick like before, then it’s fine.

However, if the syrup has developed lumps and crystals, it has gone bad, and one should avoid consuming it.

  • Try To Taste It

Another way to find bad grenadine is to try tasting it, as it can clearly indicate it.

You can take a teaspoon to check its taste; if it gives you a bad or foul taste, you should discard it.

Having sour syrup will not cause you a lot of damage except a foul or sour taste.

At first, the flavor will be sweet, but it will change to tangy as time passes.

So you can have and avoid it as per your syrup’s taste.

  • Prolonger Storage

There are times when you do not have to look for change; that is when the storage is prolonged.

Because when anyone is sure that they have stored an open bottle for a long time, there is no chance it will not be contaminated.

Thus, it would be best to avoid consuming grenadine syrup stored for a prolonged period.

If the bottle is unopened, it can be safe, so you should check its quality.

How to Store Grenadine?

  • Store at a Cool and Dark Place

There are times when you store your syrups on kitchen shelves that are prone to heat, because of which the grenadine gets bad.

Also, pantries that have direct exposure to sunlight must be avoided as they can break down the components of grenadine.

Thus, storing it in a cool and dark place will be better.

  • Refrigerate

Only unopened packs should be stored at room temperature, and others should be refrigerated within a period.

Once you open the lid of the bottle, then you can increase the shelf life and quality of grenadine.

Refrigeration also protects against pests and bugs.

  • Reseal the Bottle

If you have used the grenadine and do not close the bottle correctly, you will not be able to enjoy it for a more extended period.

That is because the unsealed syrup will dry as it has excess exposure to air and moisture.

So please reseal the bottle or transfer it to a glass jar to preserve its quality.
