Thermal flasks for coffee and drinks on the go
A thermal flask makes it easy to take coffee, tea, or a cold drink to work, in the car, or on a trip.
At Brændeholm Risteri, you will find the MiiR 360 Traveler 350 ml – a vacuum-insulated thermal flask with a 360-degree lid that allows you to drink from anywhere along the rim.
Its compact size makes it particularly suitable for coffee and other drinks when you want a reusable container with a lid for when you are on the go.
If you are instead looking for a larger container to serve several cups of coffee from, you can see our selection of thermal carafes.
What is a thermal flask?
A thermal flask is an insulated container that reduces the rate at which the temperature of a drink changes.
The MiiR 360 Traveler uses double-wall vacuum insulation.
Between the inner and outer wall is a vacuum, which reduces heat transfer between the drink and its surroundings.
This means that a hot drink stays hot for longer than it would in a regular cup, while a cold drink stays cold for longer accordingly.
The precise temperature over time depends on, among other things:
-
The starting temperature of the drink
-
How often the lid is opened
-
The amount of liquid
-
The ambient temperature
-
The specific thermal flask
Therefore, it makes more sense to choose based on construction and intended use than to expect one specific number of hours under all conditions.
MiiR 360 Traveler 350 ml
The MiiR 360 Traveler is designed as an insulated drinking container for everyday life and transport.
The model in our assortment has a capacity of approximately 350 ml and is made of stainless steel with double-wall vacuum insulation.
The size is well-suited for, for example:
-
Filter coffee
-
Americano
-
Tea
-
Cold water
-
Other hot or cold drinks
350 ml provides plenty of room for a standard cup of coffee without making the container unnecessarily large.
What is the MiiR 360 lid?
The 360 lid is one of the most important differences between the MiiR 360 Traveler and a traditional thermal flask with a small drinking opening.
The lid is opened and closed by pressing the center.
When it is open, you can drink from anywhere along the rim rather than having to find one specific drinking opening.
When you are done, you press it again to close the lid.
This provides a drinking experience more like drinking from a regular cup, while still having a closed container for transport.
Is the MiiR 360 Traveler leak-proof?
MiiR describes the 360 lid as leak-proof when properly closed.
This makes the model suitable for transport and daily use.
As with all containers with a lid, however, you should always ensure that:
-
The lid is properly installed
-
The lid is completely closed
-
The container is not overfilled
-
Gaskets and lids are clean and undamaged
Also, be extra careful when the bottle contains hot drinks.
Thermal flask for coffee
Coffee is one of the most obvious drinks to use a smaller thermal flask for.
You can, for example, brew coffee at home in the morning and take it with you:
-
To work
-
In the car
-
On the train
-
On a walk
-
On an excursion
If you brew your own coffee, you can find freshly roasted coffee and coffee beans from our own roastery.
A thermal flask does not, of course, change the quality of the coffee you brew. It simply helps to maintain the temperature and makes the coffee easier to take with you.
What size thermal flask should I choose?
The right size depends on how much you usually drink.
A model around 350 ml fits well for one large cup of coffee or a standard serving of a drink on the go.
If you need a lot of liquid throughout an entire day, a larger thermal flask or water bottle will typically be more practical.
If, on the other hand, the purpose is to keep a larger amount of coffee hot for several people, a thermal carafe is often a better choice.
Thermal flask or thermal carafe?
Thermal flasks and thermal carafes often use the same basic principle of insulation, but they have different purposes.
Thermal flask
A thermal flask is usually intended for one person.
It is practical for:
-
Transport
-
Commuting
-
Car
-
Work
-
Excursions
-
Coffee on the go
Thermal carafe
A thermal carafe typically has a larger capacity and is designed to pour several cups.
Therefore, it is better suited for:
-
The breakfast table
-
The office
-
Meetings
-
Several people
-
Filter coffee that needs to be served over a longer period
You will find our larger models under thermal carafes.
Thermal flask or regular coffee cup?
A regular coffee cup is perfect when the coffee is to be drunk immediately.
A thermal flask becomes interesting when you:
-
Need to transport the coffee
-
Want to reduce heat loss
-
Don't know exactly when you will drink the coffee
-
Want a lid on your drink
One does not necessarily replace the other.
You can easily use regular coffee cups and glasses at home and a thermal flask when the coffee needs to go out the door.
Stainless steel and vacuum insulation
The MiiR 360 Traveler is made of stainless steel.
Stainless steel is often used for insulated drinking containers because the material is robust and well-suited for double-walled construction.
MiiR uses their Thermo3D vacuum insulation between the walls to reduce heat transfer.
The outside therefore does not come into direct contact with the hot or cold drink in the same way as with a single-walled metal container.
Can the thermal flask be used for both hot and cold?
Yes.
The MiiR 360 Traveler is designed for both hot and cold drinks.
These can, for example, be:
Hot drinks
-
Coffee
-
Tea
Cold drinks
-
Water
-
Iced tea
-
Cold coffee
Always follow the manufacturer's instructions regarding which types of drinks can be used.
MiiR, for instance, advises against carbonated drinks in the 360 Traveler.
Thermal flask for cold brew and iced coffee
A thermal flask can also be used for cold coffee drinks.
If you have brewed cold brew, you can pour the finished cold coffee into the thermal flask and take it with you.
The same applies to iced coffee.
Just remember that a thermal flask retains the temperature the drink already has. If you want the coffee to be really cold, it should therefore be cooled down before being poured into the bottle.
Can you put ice cubes in the thermal flask?
Yes, if they can fit through the opening and the manufacturer's instructions do not state otherwise.
Ice cubes can be practical with water, cold brew, and other cold drinks.
Be aware that ice naturally takes up space, so the actual amount of liquid will be less.
Should you preheat the thermal flask?
If you want to reduce the initial temperature drop from very hot coffee, it can be an advantage to temper the inside container with hot water first.
Pour in hot water, let it stand for a short while, pour the water out, and then fill it with the hot drink.
This is not necessary for normal use but can be useful if temperature retention is particularly important.
The same principle can be used with cold water before a cold drink.
How long does a thermal flask keep coffee hot?
There is no single figure that applies under all conditions.
How quickly coffee cools depends, among other things, on:
-
How hot the coffee is when poured
-
How full the container is
-
The ambient temperature
-
How often you open the lid
MiiR describes the 360 Traveler as vacuum-insulated and designed to keep drinks hot or cold for several hours.
If temperature is critical to you, you should therefore consult the manufacturer's information for the specific model rather than general promises of a specific number of hours.
How do you clean the MiiR 360 Traveler?
Clean the thermal flask regularly, especially when used for coffee.
Coffee oils and residue can build up in both the container and the lid over time.
MiiR recommends hand-washing the container itself and paying special attention to the area under the button in the 360 lid.
According to the manufacturer's instructions, the lid can be washed on the top rack of the dishwasher.
Avoid using the bottle in ways the manufacturer advises against, including the microwave and freezer.
Why must the thermal flask be cleaned after coffee?
Coffee contains natural oils and aromatic compounds.
If residue is allowed to remain in the container or lid, it can affect smell and taste over time.
Therefore, rinse the thermal flask shortly after use and clean it regularly.
Pay special attention to lids, gaskets, and other areas where liquid can accumulate.
Thermal flask for work and commuting
A smaller thermal flask around 350 ml is practical if you typically take one cup of coffee from home.
It takes up less space than a large thermal carafe and can be drunk from directly.
The MiiR 360 lid also allows you to drink from anywhere along the rim.
For longer work days, you can, of course, also choose to brew coffee at the workplace and use regular cups.
The thermal flask provides the most value when the drink actually needs to be transported.
Different colors – same function
The MiiR 360 Traveler is available at Brændeholm Risteri in various colors.
The color does not change the flask's basic function.
Therefore, choose first based on:
-
Capacity
-
Lid
-
Usage
and then the color you prefer.
The availability of individual colors may vary.
