Can you put an open soda can in the fridge?

In this brief guide we will address the question, “can you put an open soda can in the fridge?” as well as other questions pertaining to the subject at hand like how to store opened soda cans.

Can you put an open soda can in the fridge? 

You should never put an open soda can in the fridge, or any opened, canned product for that matter. The rule of thumb when handling canned products is to always change the container of canned food/beverages. 

Moreover, soda contains carbon dioxide that makes it fizzy. The manufacturers introduce carbon dioxide and water at high pressure in fizzy drinks, which adds the unique fizzy flavour to them. 

When left without cover, the pressurized gas will gradually escape from the surface of the liquid. You might have noticed tiny bubbles popping out of your fizzy drinks, this is the carbon dioxide escaping from the liquid. 

Therefore, leaving any fizzy drink, or soda in this particular case, without a tightly sealed cover is never recommended. When the gas escapes, it also takes away the fizzy flavour and leaves nothing but a sugary sherbet. You might have noticed this taste if you mistakenly forgot to close the cap of your coca cola bottle. The resultant is a strong sweet black beverage that is very distasteful. 

Why should you not store opened soda cans in the fridge? 

So you opened a can of soda and are now left with some of it. Trust me, this happens everywhere. I don’t know what it is with carbonated beverages, but we always tend to leave a little bit of it after opening (unless you’re a heavy drinker). 

Now when you open the can, you have already allowed the carbon dioxide (the fizzy gas) in that beverage to escape. If you want to enjoy the fresh taste, you will have to consume it within the next 1-2 hours. However, if you wish to save it for later use, it is best to transfer it into such a container that permits airtight closure to your beverage. 

People think that if you cover the top of the can with a cling wrap or plastic, you will be able to store soda cans for longer durations in the fridge, when the reality is you will only be exposing it to more risks. 

Proper sealing is hard to obtain in metal cans with pointed edges. This will cause plastic and metal residue to be in close contact with the contents of your can. While this may not adversely affect your health, it will definitely result in a significant change in flavor and freshness of your soda. Keeping all this in mind, you should always avoid storing an open soda can in the refrigerator. 

How long do soda cans last? 

An unopened can of soda will last a few weeks beyond its mentioned expiry date. This is because the “best by” or “best before” date is just a rough estimate from the manufacturer. 

The drink should be refrigerated after you open it, because they are anyways best served when chilled. 

When open and tightly sealed, soda will last and stay fresh for upto 2-4 days depending on how tightly it was sealed. This time will also depend on how long was the carbon dioxide gas in the soda allowed to escape in the air. 

What type of container should you use to store soda? 

I will be honest, any container is a good container as long as it is keeping the fizz inside your drink. Because that is absolutely why you drink sodas! If it were not for that fizz inside the drink, you would be drinking just plain sugar with chemicals. Let’s move on to the features you should look for in a container when choosing where to pour the remainder of your drink for storage in the fridge. 

It should be airtight

Starting with the obvious one here. I cannot emphasize this enough when it comes to handling fizzy drinks. It is best to choose a container that ensures proper sealing. 

The head should be narrow

Simply put, bottles! Because everytime you remove the cover, the gas will inevitably escape from the surface of the liquid. If the head is narrow, less gas will reach the surface and it will actually prevent excess gas from leaving your soda. 

Not just regular bottles!

Another important thing to consider is the type of bottle you use to store your sodas. A regular mineral water bottle might do the job, but if you have one of those glass bottles of sparkling water, it is better to save them for this purpose. These bottles are better than ordinary plastic bottles. 

Go for tinted/coloured bottles

If the bottle is tinted, it is even better. Tinted or colored material keeps the drink at a lower temperature by preventing less sunlight to enter inside the bottle, which will in turn prevent excitation of the gas molecules. Increased temperature will excite the gas molecules, resulting in the loss of fizz from your drink every time you open it.
