Best Tips to Identify an Insulated Water Jug

by Merle

It is essential that you find the right insulated water jug for yourself. There are so many different types available in the market today, but it can be quite confusing to know which one is best for you. Here are some tips on how to identify an insulated metal growler:

Look at Its Overall Appearance

The first thing that you should consider when buying an insulated water jug is its overall appearance. It should be made from high-quality materials such as stainless steel. The material should also be BPA-free and FDA approved so that you can use it without any worries.

Shake the Jug

Another way to check if your bottle is insulated or not is by shaking it vigorously for 10 seconds or so. If you hear sloshing sounds coming from inside the bottle, then it means that there is no insulation present in your bottle. If there’s no sound coming from inside, then there must be insulation present in your bottle!

Try Pinching the Surface

Next up is checking how well insulated the bottle is by pinching its surface with your fingers. If there’s no give in at all on the surface of the bottle and it feels completely solid, then this means that there’s good insulation going on inside that bottle. So, your liquids should stay colder longer than usual if kept in this particular model! However, if you pinch and it budges in then it means there’s no insulation.

Look at the Material Used

The first thing that you want to do when looking for an insulated water jug is check out what material it is made out of. There are many different types of materials that can be used in the construction of these types of bottles; however, some materials are better than others when it comes down to insulation performance and durability. Some common materials used include stainless steel, plastic, aluminum and glass; however, each one has its own advantages and disadvantages depending on what type of insulation performance that you want from your bottle.

Other methods are:

Pour heated water into the bottle and feel the outer surface

This is a simple way to test if there is any heat transfer between the outside of the bottle and its contents. If there is no heat transfer, then it means your bottle is well insulated. However, if you feel the outer surface has turned warm or hot, then it means there’s no insulation in the bottle.

Check the seam of the bottle and the bottle mouth surface

The best way to identify an insulated water jug is by checking the seam of the bottle and the bottle mouth surface (it should have no weld integration). Insulated water bottles are made with a double-walled design, which means there’s an extra layer of insulation between the outside and inside walls. This helps keep drinks cold for longer or hot for shorter, depending on what you prefer. So, if you can see, some any weld joint found in the seam, then you know it’s not a genuine product.


Are you looking for a large container that can hold multiple beverages at once, or do you only want a small container that can carry one beverage? Either way, there are certain things to look for that will help you determine whether or not the item is an insulated bottle. Keep in mind that many manufacturers are using the term “insulated” loosely; if you’re going to spend extra money on a product labeled as insulated, you want to be sure it will keep your water cold for longer than a few hours in an average temperature environment.
