February 21, 2023 by Madelyn Doyle

From planting to brewing, people continue to improve craftsmanship in all aspects. These include ground production and coffee making. They also strive to improve the quality of the beverage by any means.

However, perhaps we all have overlooked one of the simplest steps: the storage method. Can you freeze brewed coffee for later use?

Can You Freeze Brewed Coffee?

Yes, you can, yet you don’t want to drink it later.  Because the drink itself can easily absorb the external flavor and moisture. It will have a peculiar smell if you do not use a sealed container to block the outside air.

Moreover, when taken out of the refrigerator, it will condense moisture due to the temperature difference with the surrounding environment. Its taste The taste will be off after absorbing the moisture.

Whether a refrigerator or a freezer, the food stored inside will produce “condensed water” as soon as it is taken out, which we usually call “sweat”.

For example, when we go to a supermarket to pick up a drink, the glass door will open. A large amount of moisture in the outside air will be fogged and condensed instantly, and it must wait a period before the refrigerator’s fan evacuates it.

Fortunately, the soda drinks and beer in the refrigerator have completely sealed outer packaging. Otherwise, moisture has already penetrated the food after the refrigerator is turned on and off several times. This way, the risk of deterioration will naturally greatly increase.

The same thing happens with brewed coffee. Hence, it is best to avoid refrigeration or freezing if you can’t use a closed container that can isolate oxygen as much as possible.

Although putting your drink directly in the fridge is not the best idea, you can create ice cubes from it.

Reasons To Freeze Brewed Coffee

The root of the query might come from a study on CNN when it said that there exist possibilities that drinking this famous beverage can reduce the rate of death from heart disease and stroke. At that point, this drink is a daily thing.

Freezing brewed cups is a solution for caffeinators. It makes waking up a lot easier in the morning.

Besides, frozen cups can be your lifesaver if you must prepare a lot of hot cups of Joe on short notice. One thing you need to do is take it out and make it hot again. In less than five minutes, your beverage is ready to serve.

Moreover, what if you make them in a big batch and cannot manage to finish them all? At that time, are frozen cubes a saving, not wasting kind of thing?

Still, speaking of this method, there are existing debates about whether or not to do it.

Due to the low temperature and humidity in the refrigerator, many people think storing such things in the fridge is not ideal. On the other hand, some believe it does not matter to chill this drink as long as it is sealed. They even love the aged deep flavor in the fridge more on day 3 or 4.

After all, is it possible to chill this drink properly when it is frozen?

Best Way To Freeze Brewed Coffee 

Below is the way to make coffee ice cubes:

Step 1: Make Coffee

Firstly, identify which kind and the amount that you prefer.

The best choice is to use concentrated ones. You can make a suit-you-batch-cups by remembering to calculate how much you consume every day.

It’s likely safe to drink this stored beverage for up to 3 to 4 days if you use this method. Longer than that, it probably won’t taste that good. Therefore, brewing up your best-loved cup in whichever way you prefer with a safe amount.

Step 2: Prepare An Ice Tray And Pour The Coffee Into It

Next, get ready with an ice tray. Wait until your liquid has cooled down and pour your cup of Joe into the tray.

You are not to expect to pour it when it is hot. Because putting hot substances in the freezer forces it to work much harder. It wastes a lot of electric energy and money. This act may even cause malfunction to your freezer in the long run.

Step 3: Put The Ice Tray In An Airtight Container

After that, you need to cover the ice tray.

The most important thing is to cut off the light and outside air when preserving such drinks. Because it will start to rot if it comes in contact with oxygen, various odors in your freezer can seep into your cubes.

No matter how much you expect to preserve, you must have a closed or sealed holder to keep it safe in the ice tray.

A glass holder can preserve the flavor, and it’s easy to clean. A plastic one is cheaper, but it’s hard to wash away the aroma. You either use it solely to store your cup of Joe or use a disposable plastic container.

Tinned-can can be an option, but it is expensive. You have to find the one specializing in acid liquid to avoid chemical reactions between metal and acids from the beverage.

Step 4: Freeze It

Next, you put it into the fridge. It will take about two, four, or six hours for those cubes to freeze completely. The process also depends on the drink and the freeze’s performance.

Last but not least, prepare a mug to put on your table. You will need it for some awesome recipes we are about to share in the next paragraph.

Milk, cream, and other products which are from dairy will surely change their appearance immediately when they are open and being frozen. They become grainy. In the end, the original flavor will disappear, and the taste will change.

4. Does Freezing Brewed Coffee Reduce Caffeine?

Yes, it does. But only when you let it directly into the fridge without a lid.

The air in the refrigerator is cold and dry, which easily evaporates the moisture inside the cup, causing the aroma to dissipate. In addition, when things are stored in the refrigerator for a long time, there will be a lot of unpleasant smells, which will spoil the taste afterward.

Despite that, it is not easy to happen if you let it stay in an airtight container. Caffeine is fairly stable. It will not degrade significantly in baked beans or brewed cups as long as you preserve it standardly. Never let it be hygroscopic.

You can store roasted beans for about one month and vacuum-stored beans for two months. The lifespan of caffeine is around four years. Therefore, the confirmation that the amount of caffeine content will decrease in the refrigerator for a few days is not accurate.

Few humans feel the taste is milder than before if you put it on the fridge because the ground is sunk to the container’s bottom. You only scoop it on the surface, so the chance of getting more water happens, making us feel like it contains less caffeine.

Yes, it is ok. Decaf is a kind that has removed 97% of the caffeine content. So, freezing decaffeinated brewed cups has no different process from regular cups.

If it does not taste good as usual, you may want to re-check how you freeze it. If you follow exactly the method, problems lie in the quality of the box you buy itself.
