What is the nitrogen capsule in beer for?
Beer with a nitrogen capsule is a drink that is only slightly enriched with carbon dioxide. Instead, this function is performed by nitrogen, which is placed inside a special capsule. It is placed at the bottom of the jar or bottle before the container is sealed.
The capsule is presented in the form of a small ball made of PVC. Its diameter is approximately 2 centimeters. The capsule has a small (one) hole through which nitrogen enters the drink. It acts as a catalyst in the formation of foam.

In order to understand how a nitrogen balloon works, you need to imagine the situation: the manufacturer brews a drink, pours it into cans or bottles. Next, a plastic ball is placed in the container.

When you open the can, the indicators drop, nitrogen pushes the drink out of the balloon and into the beer container. This allows you to create a beautiful and stable foam.
