Does iced coffee go bad in the fridge?

The iced coffee can last approximately one week or even two in your fridge without going bad as it is only a mixture of water, sugar, and ground coffee and these things do not go bad that quickly. But we do not recommend you to consume an iced coffee that is more than a week old as at very least it would have developed sharper and acidic flavour.

Moreover, the iced coffee that already has milk added to it has a shorter life span, approximately it has the same life span as that of the dairy product. Therefore we recommend you to consume your iced coffee having milk before a week preferably within 3 days. So if you have plans for storing your iced coffee in the fridge we recommend you to keep the coffee and milk separate and mixing it for each serving individually.

One more thing to consider along with the time is to use an airtight container or bottle to store the coffee so that it will not pick the smell of other foods placed in your fridge.

Does iced coffee go bad at room temperature?

The iced coffee will not taste the same if you drink it after putting it for more than a day out at room temperature and most probably it will taste more bitter. Moreover, the iced coffee with added milk won’t last more than 8-12 hours at room temperature in the summer. So we recommend you to consume your brewed iced coffee placed at room temperature within 24 hours.

How to make iced coffee?

Iced coffee is made by simply brewing the coffee in your regular way and afterwards adding it over the ice cubes placed in your glass or mug.

Another way you can try is to make strong and concentrated espresso shots from your coffee maker and afterwards take a cocktail shaker. Add the coffee shots and a lot of ice cubes in it. All you have to do afterwards is to shake, shake and shake and voila! You have your flavourful and frothy ice-coffee. Now it is up to you if you want to add some milk or sugar syrup in it. Be a barista and customize it your own way.
