Before we get to the heart of the matter, and find out what effect the fridge has on the contents of your insulated bottle, it's important to know how your reusable water bottle works.

So let's start with a quick look at how a stainless steel water bottle works, and then see how to take advantage of the fridge to get a cool drink.

Will the fridge damage my insulated bottle?

First, let's understand how your stainless steel water bottle is made. To keep warm and cold, your insulated bottle is carefully designed with two stainless steel walls and vacuum separating them. This prevents heat and coolness from dispersing, keeping your contents at the ideal temperature. We have written a full article explaining how an insulated bottle works, you might be interested!

Now you know the secret of your reusable bottle to keep the temperature constant. So, do you think the fridge can damage it? The answer is no.

Can the refrigerator be used to have a cooler drink?

It is important to understand that if you place your filled insulated bottle in the refrigerator, the contents will not get cold. It was made to keep the temperature of your drink.

Nevertheless, the fridge can be useful to have a cool drink! The little trick is to put your opened water bottle in the refrigerator, before filling it. This simple gesture will allow the stainless steel to cool down and thus lose less freshness when you pour your refreshing drink. This will reduce the temperature difference between the container and the liquid, which will result in a balance with less loss. The physical phenomenon that occurs is thermal conduction.

To cool stainless steel more quickly, you can place your open bottle in the freezer. However, you should not place it full in the freezer, it could cause great damage to your reusable bottle!

Finally, the refrigerator will keep your drink cooler for longer. By keeping your water bottle in a cool environment, your contents will not heat up quickly.

Why shouldn't I put an insulated bottle in the freezer?

You should not confuse a freezer with a refrigerator, because the processes are completely different! The fridge will keep a temperature between 0°C and 7°C, which will not produce any freezing. On the other hand, the purpose of the freezer is to freeze what is inside by adopting a temperature generally between -18°C and -24°C.

Let's go back to physics class. What happens when a liquid freezes in a bottle? Its volume increases and the bottle bursts!

Although our stainless steel bottles are designed to withstand extreme temperatures, if exposure to negative temperatures lasts for several days, your drink will start to freeze. This will cause your liquid to solidify and its volume will increase. The consequences will be deformation of your insulated bottle, and in some cases it will become unusable.

Our experts seriously advise you not to put your full insulated bottle in the freezer.

We now see more clearly the role of the refrigerator to keep your liquid cold in the stainless steel bottle. To do this, it is necessary to have a fresh drink in the first place.

Let's discover together the 3 simplest methods to refresh water quickly.

Put ice cubes in the bottle

We don't always think about it, but having a supply of ice cubes in the freezer can really come in handy! If you don't have time to wait for your drink to cool on its own in the freezer or refrigerator, we recommend adding ice cubes. In a very short time, your water will be nice and cold.

Also, if you are using one of our insulated bottles, it is important to know that the ice cubes will keep your drink cold much longer. The ice cubes trick has a double advantage!

Put the carafe in the fridge before filling your water bottle

A second simple trick to see a very cold drink before putting it in your stainless steel gourd, is to put the carafe in the fridge. Generally, it is necessary to wait a few hours before the content cools down, that's why we advise you to put it in the fridge the day before.

By doing this, your drink will always be cold before you leave. Take this good habit!

Add frozen fruit

Our latest method is also one of the most original. It consists in putting frozen fruits in your reusable bottle. They'll act like ice cubes and help cool your drink considerably. In addition to cooling it down, the fruit will add a slight flavor that will delight your taste buds. Personally, I opt for raspberry. It's up to you to choose your favorite fruit or among them!

Use your refrigerator to keep your drink fresh

As you can see, the refrigerator does not allow you to cool the liquid in your insulated bottle. However, it can play an important role in keeping your drink cold. It will first of all allow the stainless steel to cool down before pouring the liquid, and it will also keep your drink cold for longer.

You are now an expert at keeping your drink cold in an insulated bottle. You know exactly when to use your fridge and freezer!

It is important that your liquid is cold before you pour it into your stainless steel bottle. If this is respected, you will simply have to maintain its freshness.
