Tumbler Cup Buying Guide
What is a tumbler cup?
This is probably not a strict secret that most people’s day begins with hot drinks such as tea or coffee. But early in the morning, unfortunately, not everyone has enough free time for decent tea and in this case, the purchase of a tumbler cup makes sense. Thanks to this mug, you can take your favorite drink with you and enjoy it on the go. An insulated cup serves to keep warm or cold different beverages. This is possible because such cups are equipped with a double wall and have a unique vacuum construction in between. Such a useful invention may be used both in everyday life, e.g., B. on the road, as well as during a hike or fishing. The advanced tumbler cups also offer away.
These cups are usually only used by one person, so if you need more capacity, then look for a tumbler cup that can be bulkier. But if you do not just drink on the go, but also want to get something between the teeth, then the plastic food storage boxes, which are also ideal for warming up in the microwave ideal.
How to choose your insulated mug?
Small accessory very useful, a small insulated travel mug can quickly become essential. To be able to choose among the multitude available on the market, here, in my opinion, are the necessary criteria that will have to be taken care of before setting your sights on a model.
Composed mainly of stainless steel, the insulated mugs allow keeping your drink in a material compatible with food and resistant to rust.
Being also partly made of plastic (mainly the lid), it is essential to ensure that it is free of bisphenol A, so that there is no release of toxic materials when in contact with the drink, especially with hot beverages.
For sanitary reasons, obviously, and for taste reasons (to be able to appreciate your freshwater without the taste of your coffee of the day before, it is top), it is recommended to choose a model that is easily washed in the dishwasher, cover included.
This will guarantee a good wash and will ensure to get rid of odors and stains left by the previous drink, if necessary, and without much difficulty. Of course, in this case, choose a model that is easy to disassemble and that does not include too many sub-parts (ideally only count the body of the mug and lid).
The capacity chosen for your mug depends mainly on the use you intend to make.
As you only want to use it for your morning coffee or to replace the disposable plastic cups offered by the coffees, a size of 300/400 ml is more than enough.
On the contrary, if your mug is intended to contain your drink for the whole day or several people, you will have to opt for a much larger container, about a liter.
Of course, opting for an insulated travel mug, you are mainly looking to keep your drinks hot or cold for a while. According to the cups, the isothermal efficiencies will be quite variable, because they are often correlated with the investment price.
However, it is advisable to think about the use you want to make, because sometimes it is not necessary to invest a lot. If you’re looking to keep the temperature of your drink just a few hours, then most mugs will do the trick.
If, on the contrary, you need your drinks to stay hot or cold for long hours, you will need to invest a little more.
In any case, check that the chosen model is well sealed, which will allow you to keep your mug closed in your purse, and not having to always keep it straight in hand.
Know that the capacity of your mug will directly affect the portability of it.
Thus, it will be easy to slip the mugs of less than 500 ml in your purse (provided that it is well sealed) while the larger ones will have to be carried by hand, or in a backpack large enough.
The capacity will also undoubtedly play on how you will drink your beverage. Thus, in general, large mugs of about 1 liter do not drink directly to the mouth, but often have a cap that serves as a cup.
As a result, two hands are often needed to serve, not ideal for transportation or walking on the street, although quite suitable for hiking breaks, for example.
On the contrary, the smallest mugs are used without worry like a cup, often with a suitable lid to reduce the risk of splashes and burns. Ideal if you intend to use it while walking or driving when you have only one hand free.
As mentioned above, the size of your mug will make it an object more or less convenient to use.
The bigger ones, around 1 liter, often have a rather simple hermetic cap, which you unscrew and then pour your drink into the cup.
The small cups that are drunk directly like a cup compete on the way the lid works since it must act as an airtight closure while letting the liquid pass without getting burned or put everywhere.
Some of them work with a simple airtight shutter while others have more sophisticated systems such as Contigo’s auto seal technology, which allows the mug to close automatically between sips to avoid any risk of spillage. Press the small button on the opposite side of your mouth to take a sip and then release to close, all with one hand, of course.
This system can be paired with a Cleanguard protection cap that allows it to be rotated to cover the tip, so it stays clean while locking the auto seal button.
Manufacturing technologies Production
Technologies that make a tumbler cup are also critical. To keep your favorite beverage cold or warm for a long time, consider the models with a double wall and vacuum technology. Thanks to vacuum technology, the liquid is kept warm or cold in a cup. But if you do not need to keep the temperature of your favorite beverage constant for a long time (for example, you’re entirely exhausted when driving), then you’ll want to consider the models that have the double-walled air. This solution allows the cup to be comfortably held with one hand without burning.
Comfort The user comfort of an insulated cup also plays an important role. The correct placement of the outlet ensures comfortable and safe drinking during the movement. Furthermore, if you want to use the isolation cup in a car, then look for the models that are equipped with rubber pads for more stability while driving. For everyday use, the models are most suitable, which can be disassembled with ease. Such tumbler cups are easy to clean under running water and are dishwasher safe.
Whoever spills flies out. A coffee mug must always be tight when traveling. Insulating cups that do not reliably fulfill this criterion are not even included in the test.
Here’s the question: Can this cup also call tumbler cup to go or is it cold coffee? The longer and better he keeps your drinks warm or cold, the better the grade for a tumbler cup in this category.
Is the part clean again? When cleaning, we look at how easy it is to clean the coffee tumbler cup and if any leftovers can settle and form unappetizing edges. The question of the suitability of the dishwasher also affects the asterisks. Hand wash gives point deduction. Iso-cups that you can fish cleanly from the dishwasher, get pluses.
You can also drink a thimble of coffee at home. In a tumbler cup on the go so a little purer fit. The larger the capacity of a thermal mug in the test, the better it cuts off in this category.
Does the iso-mug fit well in all standard mounts and is it also stable on the ground? Then he gets good grades from us.
For a tumbler cup to be called “eco,” it has to do more than save paper cups. If his conditions of production are fair to the environment and the workers who make him, he stands well in this ranking. If the production conditions are unclear or even ugly details come to light, there is a deduction of points.
Those who give a guarantee are convinced of the quality of their products. A warranty from the manufacturer is, therefore, a good indicator of longevity and thus worth a proper evaluation.
Of course, there is no Ferrari for the price of a bicycle. If price and performance fit together, you can look forward to full cup of a coffee mug to go.
In short, many different systems to ensure a perfect seal, a hygienic system and always hermetic.
Some tips and tricks for insulated coffee mugs
Stainless steel insulated cups are an integral part of your everyday life? Then maybe you have even more fun with the hot coffee cups with our tips and tricks.
1. Longer warm or cold
This trick helps you to keep your coffee or tea hot longer: You fill hot water in the Iso coffee mug and leave it for a few minutes. Then you dump the water and fill up your hot drink. You can do the same with ice-cold water and cold drinks.
The principle behind it is very simple: the water heats or cools the wall of the tumbler cup. It absorbs or releases energy from the cup wall and becomes colder or warmer. The actual drink loses a few degrees less while filling and thus keeps its temperature longer. Your drink stays hot or cold for up to 25% longer with this trick.
2. Shake it, baby!
Speaking of cold: Give me a milkshake or a smoothie and some crushed ice in the vacuum cup. So you have in the iso-mug to go in the summer always a delicious refreshment.
3. DIY tumbler cup
You can also design your tumbler cup and make it unique. For that, you can print or engrave(let) them with the most different pictures or a cheeky saying that suits you and your coffee to go. You can do that with the cups from our tumbler cup Test. Some cups also offer the option to put pictures in a dedicated holder.
How to use a tumbler cup?
It is very easy to use an insulated coffee tumbler cup. Here is a quick tutorial on the different steps to follow:
- Heat the water if you want tea or coffee. If you prefer hot chocolate, heat milk.
- Pour the boiling liquid into your tumbler cup.
- Add coffee, cocoa powder, or your teabag.
- Close your tumbler cup hermetically.
And now, you can take it everywhere with you without a problem but be careful not to burn yourself!
If it is an insulated mug with a lid as a cup, unscrew it and pour your drink into it.
How to clean a tumbler cup?
Maintenance requires cleaning. Do not let the dishwasher systematically do the dirty work. Some models can not be cleaned in the dishwasher. Wash it by hand, without using too much detergent that could damage your tumbler cup. Corrosive products based on chlorine are strongly discouraged and even less bleach. It would be best to use dishwashing liquid or hot water and soap.
To increase the life of your tumbler cup, be sure to follow some basic guidelines, starting with never putting the tumbler cup in the oven to heat it. Pour your drink first into a container suitable for this purpose. Do not let the drink ferment in the tumbler cup for several days. Make it a habit to clean your insulated mug every night after use.
Frequently Asked Questions
What materials are the thermal mugs usually produced from?
Tumbler cups are usually made of high-quality stainless steel for enclosures and food safe PVC-free plastic for lids. Some models also have an inner layer of copper to keep the drink warm.

Yes, that’s true. A closure system with good seals ensures safe transport of the cup and prevents unwanted dripping of the liquid.

The rubbers should also be cleaned to prevent the formation of unpleasant odors and the proliferation of bacteria.
