Most likely you are drinking your coffee with bad milk. And the fault of everything has a factor: the temperature

There is a scene that you have surely lived if you have asked for a coffee in a restaurant or a cafeteria: you ask for a coffee with milk or a capuchino and, after assembling value, you ask that the milk is not very hot. That is when such a coffee serve you darkness And you hear the crackling of a milk that ceased to be a edible product to become a lava. And there is something important to take into account in all this: although the coffee they use is good -Not Torrefacto-, such hot milk is ruining the drink. Specialty coffee shops against lava. Prepare a coffee It is a very meticulous process. The problem is that the coffee culture of many sites is quite improvable, which has led us to think that the way of drinking any preparation that is not a single with ice must be an experience in which we have to spend ten minutes waiting for coffee to cool. The difference between a specialty cafeteria and any bar is not alone in coffee, but also in how they treat milk. And that is where the temperature comes into play. In specialty coffee shops, any coffee that carries milk will be rather temperate. You can even start taking it as soon as they serve you. This is not for Eviction the table as soon as possible and that the following client passes, but for something deeper and that has a scientific basis. 65 ° C.. That is the maximum temperature that the milk of a coffee with milk should have. Anyone between 55 and 65 degrees Celsius, happens to be more accurate, and maintaining it is crucial to protect something fundamental in milk: its proteins. When we heat the milk with the foamer, if we stay in that temperature range, their proteins experience something called ‘denaturation’. This means that milk proteins lose their structure and form spheres around the air bubbles that are produced when milk subjected to the sparkling. That process, together with the interaction between the casein and the fat of the milk, serves to stabilize the foam, making it more creamy. The sweetness of the liquid is also enhanced without falling into the burned of it because the natural sugars of milk break down just as not to pass. And? If we pass temperature, the balance between fats and proteins is broken, so the foam will be more airy and lose that softness and creaminess, making the drink less dense. But apart from the aesthetic function (because the art is worse with milk that exceeds 65 degrees) and the alteration of the texture of the drink, there is another issue that we must take into account. When we exceed the temperature, the proteins are excessively denatured, which leads to the excess of air bubbles that we have already commented, but also to the presence of a flavor that can be unpleasant because the sugars are passed and the fats are oxidized. In addition, the texture will not be so velvety and we will not only have a much flatter drink in flavor, also in terms of density. Template, better. And it happened to me. Going to a specialty cafeteria for the first time and finding a tempered capuchino was a surprise, but beyond the initial by temperature, the next was that there were fruity notes of the coffee I could appreciate. Preparing the same type of coffee in my house, with a foamer who later saw that it exceeds that temperature, all those notes, simply vanished. My mistake during all that time? Do not pay attention to temperature. And that temperature is one of the many reasons why drinking coffee with milk in many countries, and out of specialty coffee shops, is a battle. Preparing good coffee is very complicated, so much that there are those who study What are the best reactions and temperatures To, among many other issues, heat the right the milk to change the texture of the drink without affecting its flavor too much. Ojito with reuse. On the other hand, and I recognize that it has also happened to me, we cannot reuse the milk that we have already subjected to this process in the foamer. The scene may sound to you: it is one of the first times you make coffee with your new coffee maker and you throw more milk in the jar. That goes up as it is foam, so we have half left and we decided to take a glass jar, let it temper and store it in the refrigerator to use it in another coffee. We spread it again and … there is the error. It’s something James Hoffman –Barista and coffee disseminator- already explained A few years ago: when we heated milk for the second time, we are exaggerating the denaturation of proteins and promoting oxidation of fats, which generates a more stale flavor and an unpleasant texture. Therefore, if you want to prepare a better Latte At home, it is best to have a steel jar that allows us to feel the ideal temperature and, until we have trained the sense of touch to identify what that temperature is, something like a cheap kitchen thermometer will serve as a guide.

Science has the explanation

It is becoming increasingly clear that there is no “normal” body temperature.

If you ask us what the “normal” temperature of our body is, the instinctive answer will be 37º Celsius. When the thermometer exceeds that mark, we usually talk about fevermild or high depending on how far we move away from the figure. However, over time health experts have realized that the reality is a little more complex. The body temperature issue It is not a mere curiosity. Fever is an important response of our body to many diseases or disorders, generally to infections. The fever It is a double-edged sword: our body raises its temperature to try to kill viruses and bacteria that may be damaging it, while activating our body’s immune response; However, in the process, fever can also put the proper functioning of our organs at risk and cause other problems such as dehydration. Since fever is a common response to various illnesses, it can also cause us serve as a diagnostic toolto narrow the circle on the possible conditions that affect us. Answering the question of what is the “normal” temperature of our body is difficult. And the reasons behind this are several. Firstly, because, over the last century and a half, the estimated average temperature of the human body has been reducing. The notion that our body temperature It is at 37º and dates back to the mid-19th century. In 1868, the German doctor Carl Reinhold August Wunderlich conducted a study using 25,000 patients and more than a million temperature measurements. From these data, he calculated that the average temperature was 37ºbut also observed certain deviations. However, more recent studies have observed lower average temperatures. A recent example of this we found it in a studio Made in the United States and published in 2020 in the magazine eLife. The analysis indicated that Americans’ body temperatures had been dropping at a rate of about 0.03º Celsius every decade. A previous study conducted in the United Kingdom and published in 2017 in the magazine B.M.J.estimated an average temperature of 36.6º in its sample of more than 35,000 participants and 250,000 measurements. We don’t really know why body temperature has been reducing over time. A possible explanation It lies in the improvements in hygiene and immunity, which would imply a lower incidence of infections in the population and therefore lower average temperatures. But this is just one of the various hypotheses that seek to explain the phenomenon. Wunderlich himself observed in his study that men and older people tended to have lower body temperatures, while women and younger people had higher temperatures on average. Which brings us to the second reason why establishing a “normal” reading is especially difficult. And it depends. Sex and age are two of the factors that can make what is “normal” for one person not “normal” for another. But other factors can also alter this figure. a study published in 2023 in the magazine JAMA Internal Medicine measured the degree to which these factors affected body temperature, but also added new variables such as height, body mass, and the time of day at which the measurement was taken. Among the sample of 618,306 observations, the average temperature was at 36.64º Celsius. Among the participants, the average readings for each individual ranged between 36.24º and 36.89º. It is also worth remembering that there are different ways to measure body temperature (tympanic, oral, axillary…) and that each one It presents some slight associated deviations. So at what temperature fever comes? As is evident after what we have read, the answer is that it depends on each person and situation, although fortunately, with the variations being less than one degree, the interpretation of the results of a thermometer may not be as different from the conventional one as to affect decisions such as whether or not to stay home during a cold. However, for health experts, having better knowledge about these variables can be of great help. That is why new studies have also investigated this question. One published in November of last year in the magazine Scientific Reports by South Korean researchers, analyzed the body temperature of 9,195 hospital patients through tympanic temperature measurements (the tympanic temperature It is usually half a degree above the oral measurement and about one degree above the axillary measurement). The team estimated an average temperature of 36.91º Celsius, and a limit of 37.81º for fever.
