Have your friends recommended a thermal glass to enjoy your favorite beer and you have no idea what they are talking about?
Do not worry, are all settled, because we are talking about a new concept and little known until now. The double-walled glasses have just arrived and have come to stay.
The thermal glass.
The first thing that strikes a thermal glass when you have been using it for a while is that your brain is accustomed to having the drink warm at a certain speed and when you use the double glass, the speed is different, slower. When you drink 10 or 15 minutes and your beer is still cold, you think why I have not had one of these glasses until now?
Another difference is the contrast between the glass temperature and the interior temperature. When you pick up the glass your hand feels warm and when you drink notes like your drink is very cold.
If we go to its most basic definition, we can say that a thermal glass is a glass that serves to maintain the temperature of the liquids it contains.
However, this definition falls short in order to make our readers understand all that a current thermal glass can mean for them.
And we are not talking about the typical “thermo” that we have all filled with water or coffee ever. The current thermal glasses are revolutionizing the market thanks to its incredible features and performance.
Types of thermal glasses
In fact, to date, we can find thermal glasses of various types: those that are more like a thermos, thermal cups, thermal jars, coffee cups, long glasses … The variety is incredible but, finally, all offer The same thing: keep the temperature and properties of your drink for longer so you can enjoy it 100%.
Thermos glass open
These have very varied forms, ranging from the inverted form of bottle, striking but impractical indeed, to beer glasses passing through the long thermal beer glasses or the typical sized glass.
Other designs are the typical glass for coffee with milk, the cup of tea to thermal wine glasses.
Every glass that you can imagine can be made in double layer giving you the advantages of insulation.
The characteristic of this glass is that it is closed. This means you can take it from one place to another to enjoy our drink anywhere, without spills, without problem… There are glasses suitable for beer or wine if you like to see what you are drinking as they are usually opaque.
How does a thermal vessel work?
A basic concept, heat transfer always occurs from the hottest part to the coldest, a cold drink will gain heat and a hot drink will cool, so far simple?
Heat is transferred through the glass walls from the outside to the inside. The good news is that these process can be mitigated.
For a single glass, the temperature reached inside the glass will depend on the thickness of the glass and the exposed surface. It will not vary from one to another since the simple cups are not designed to maintain the temperature.
When we have a double glass this transfer is very attenuated to have two surfaces with an insulating layer in the middle. The operation is similar to that of a double-glazed window.
In addition, the heat will not transfer from our hand as the inner part is totally isolated.
And you ask yourself, how does this double wall act? Does it really work? What benefits do you get?
Well yes, it works, a double glass keeps your drink cold 2 times longer at its optimum temperature than a simple glass. Yes, double! The drink will continue to heat but much slower than with a simple glass.
The higher the outside temperature the more you will notice the difference between the double and the single vessel.
Characteristics of a thermal vessel
Knowing all this, we proceed to define what are the characteristics of the different glasses, also called double layer.
The double wall attenuates that the materials transmit their cold or heat.
This is a point to keep in mind since the low quality glasses do not have the opening between the two walls sealed, so when washing the water and detergent will remain inside to deface the appearance of the glass.When you go to buy your double-layered glass make sure it is sealed if you do not want to have a dirty glass forever
Normally, that lid of which we speak that prevents that the air is mixed with the liquid, is hermetic. This means that it is closed to lime and edge so that the protection is maximum. In addition, this avoids dripping, which means that we can take our thermal glass wherever we want and drink our drink several hours later.
Material and color
Depending on the type of glass, we find them in borosilicate glass, plastic, stainless steel, thermoplastic … The closed thermal jars usually find them in opaque and mirrored colors, as we have said before, to maintain the cold or the heat for the maximum possible time. What we do advise is that we always look for materials and models that can be put into the dishwasher or used in microwave if we want to heat them.
In the case of glasses with lid, these are usually quite large, because it is understood that we are going to take our drink to spend the day outside. The open thermal cups, in turn, have different sizes, since, as we have said on a couple of occasions, they are made by imitating the shape of the conventional containers: jars, jars, mugs, beer glasses, glasses …If your purpose is to use it to drink the beer cool you are interested in a glass from 330ml to fit the contents of a can or bottle.
What thermal glasses do we find?
Nowadays the thermal glasses are becoming very fashionable thanks to their great utility. Therefore, it is not surprising that more and more models of different thermal vessels are being created.
Glass of thermal beer
This is ours, hehehe. A glass of beer. Height and width. The one of all the life. We can keep the beer cool for almost half a game of football.
Who wants to drink hot beer, which has slowly been losing properties? With the beer glasses you forget about this. In addition, its double wall technology prevents the glass from exuding and wetting everything so you do not need coasters.
It’s the best glass of beer ever.
This one has the same characteristics as the previous one (fresh beer and with all its properties during many minutes). However, its shape and capacity are different, designed for larger quantities of beer and to serve several friends during an event.
Thermal wine glass
Wine is a drink that has an optimum point of very narrow consumption. That is, if it is very cold you will not notice the nuances and if it starts to be hot you will not be able to drink it.
That is why the glasses and thermal cups to maintain the temperature for more minutes are also optimal for mainly white and rosé wines.
For a red wine it will also work and you can enjoy its aromas all the time. Using a glass of wine, elegant and fine design, you will ensure you take the right wine at its optimum temperature that corresponds, without hurry, and you can enjoy it without being hot or without being able to drink.
Glass of thermal tea
The thermal tea cups are the latest novelty, because, taking advantage of how well they maintain the heat, they allow you to make your infusion inside them.
Thus, the glass of thermal tea can also include an infuser, where to put the herb that you like so that, with the water well heated, it will detach its essence and enjoy a tea made completely to our liking. A blast!
Glass of thermal juice
Going back to the cold drinks, and leaving aside the delicious spirits, we can drink natural juices – or not – in a thermal glass of juice. They are flat, elongated, thin, thick …
They are, as we said, the most similar to the term of all life. It is a cylindrical container, large and opaque, with lid, which will retain the temperature of your drinks for a long time, and can carry them. The most advanced models offer up to 15 hours keeping temperatures cool, and 7 for hot models.
Finally … A curiosity about thermal glasses!
The thermal glass was conceived more than a century ago, concretely in 1881. The curious thing is that it was a physicist who made them, looking for the way to store helium, oxygen and nitrogen respecting its low boiling point.
And to think that thanks to this we can now enjoy a delicious drink at a perfect temperature and with all its properties.
