Which is better for cold beer: a can or a bottle?

There are those who prefer to drink beer in Can and who believes that rejection cup it’s almost blasphemy. As is often said, there are as many flavors as there are colors, and the truth is that the choice of one or the other container is ultimately more a matter of taste. individual preferences. In fact, while it’s often said that canned beer tastes worse, we’ve recently seen that this claim actually has a high psychological component.

In that previous article hypertext we evaluate how the material affects taste and safety of beer. But the truth is that there are more factors that we can consider when choosing one container or another. For example, how easy it is to recycle materials or how long it takes beer to cool or warm up.

Both questions are very relevant, which may possibly tip the scales in favor of one container. Although this raises the question quite even.

Where is the best beer temperature maintained?

In 2008, two scientists from loyola University, in Maryland, they did a study to find out what material best kept beer cold. In it, they proceeded from the fact that thermal conductivity of aluminum, from which jars are made, is 150 times larger than glass. This would indicate that can cool down faster, but also reheat before taking them out of the refrigerator. In addition, the walls of the cans are thinner than those of bottles, which will enhance these results. However, when it came to the truth, the differences were not so great.

And this is what is both experimental and with computational models, observed that when exposed to room temperature, “glass and aluminum bottles behave almost identically in regards to keeping their contents cold.” In fact, both vessels showed an increase of approximately 15°C in about 2.7 hours.

On the other hand, computer simulations have shown that when a jar is immersed in an ice water bath, “the liquid cools faster than in glass due to lower thermal resistance aluminum compared to glass. This data may tip the scales in favor of beer cans. However, this is offset by the fact that, holding a glass bottle in hand, beer heats up slower than a can. So it all depends on what we are really looking for.

What material is best recycled?

The planet is out of control for many reasons. Much of what is happening is beyond our control and requires institutional intervention. However, as consumers, we can perform small actions such as processing.

Therefore, when assessing which container for beer is better, one cannot ignore ease of processing your materials. And here everything is initially smooth, although there is one material that stands out.

It is true that both glass and aluminum can reach be 100% recycled. Therefore, we can easily dispose of the packaging in an appropriate container. However, if we also take into account the energy saved, there is one material that stands out. And this is what, according to the statements euronews from the co-founder of Cranes Drinks, Dan Ricemathey chose canned cider precisely because energy that is stored from your disposal.

Since cans are lighter than glass, much more energy is saved when they are recycled and put into circulation. On the one hand, while they save with a bottle 42 kWh of energythere are savings with the bank 14,000 kWh. In addition, with glass they save 19 liters of fuel and with beer cans you reach 6545 liters. It also takes into account the saved space on the landfill, which is 1.53 cubic meters with glass and 7.65 cubic meters with an aluminum can.

So while the differences are small, it does seem that a beer can is better than a glass bottle based on temperature, ease of processing, and energy savings. Even though your brain tells you that its content tastes much worse.
