The Japanese company Nendo has presented an innovative solution to the problem of beer foam in the can. They have designed a new can with two rings to achieve the ideal amount of beer and the perfect foam.
Beer is delicious and even refreshing for many people, but when the drink is poured into a glass, the foam usually falls off and spoils its true flavor. However, an Asian company has found a solution to this problem.
A group of scientists, in collaboration with the Japanese company Nendo, have presented a new can design that could solve the situation. Is about a can with two rings to achieve the ideal amount of beer and the true flavor of the head.
The two rings allow you to open the can in two different ways. When opening the first ring, the beer pour the liquid, and seconds later the second ring must be opened to have a perfect foam, without spills.
Although this design seems simple, it is not, since researchers spent years finding a way to enjoy a beer with perfect foam. They used physics and mathematics to design this can.
The perfect beer can with the can with two rings
Nendo, the Japanese company behind this invention, stated the following: “There are two fundamental principles of the bubbles that form from canned beer, in addition to the factor derived from its raw materials”.
The first principle is said to be the sudden drop in pressure inside the can when it is opened. While the second principle is the friction that occurs between the can and the liquid.
Thus, it has been concluded that when the ring does not fully open the can, the pressure is concentrated in the narrow opening. Also, when pouring, you increase the area of the beer in contact with the lid, making it easier for bubbles to form.
The properties of the lid and the distances between the tabs of the rings change when a can is opened. Thus, with the new can, it is recommended to open the first ring first and pour the beer halfway into a glass.
Wait a few seconds until the bubbles settle. After opening the second ring, allowing the can to open completely, at the end, you will have a glass of beer with the perfect foam ready to drink.
This two-ring tin is part of the new designs that manufacturers will be adopting in the near future. It is similar to the caps for Coca-Cola, milk and other drinks that are being introduced throughout Spain.
