Claudio Pellegrini, a professor at the Federal University of San Suão del Rey in Brazil, declared the country’s optimal mouthpiece shape. The stated problem attracts students’ attention to boring mathematical calculation problems that are understandable to everyone. The discovery did not happen – the professor was only a mathematical proof of the benefits for beer.
In his calculations, Pelegrini relied on the need to keep the beer at a comfortable temperature as much as possible. In a reverse passive way, by reducing heat exchange with the environment, which is why the shape of the glass is important. In the case of Brazil, this is a serious problem. In low zones the temperature is regulated to +38 ℃ and the wind rises, the beer becomes warm and tasteless in just three minutes.
The professor talked himself out of the fact that the glass would have a thick bottom. or some kind of stand with isolated phenomena. From selected factors such as the extreme temperature of human hands. In his studies of simulated thermal processes using classic glasses – Weizen, African tulip, imperial pint, straight glass.
In this case, Pellegrini took advantage of the fact that he was also interested in support and upward expansion with the coefficient of bending of the walls. First of all, the form below can be used as efficiently as possible. slowly. The shape is the same as a pilsner – tall and thin. a glass that is prepared to form a proper foam head at the top of the container.
