Even as the craft brewing industry has grown and beers have become more diverse, the struggles when packaging beer have remained, with oxygen being the main cause. A reactive element, oxygen tends to be absorbed by beer, which reduces shelf life and can alter flavor and aroma profiles that a brewmaster worked hard to achieve. Vacuum Barrier Corp. combats the effects of oxygen by using nitrogen, an inert gas. By replacing oxygen in a container with nitrogen, the unique taste and bouquet of the beer can be maintained, the company says.

Another advantage of nitrogen is its ability to be stored as a liquid. Involved with the brewing industry since the 1980s, Vacuum Barrier specializes in extremely precise, efficient, and reliable liquid nitrogen dosing systems. For instance, the company’s Linerter excelled at pre-purging empty bottles of all sizes prior to filling. Providing a low-oxygen environment for filling helps extend shelf life. Additionally, the compact Minidoser provided a simple solution for purging oxygen from the headspace of filled bottles just prior to capping.
