The use of nitrogen in winemaking offers an effective solution against oxidation, deterioration and bacterial growth. This element has become an indispensable tool for winemakers, helping not only to preserve the integrity of the wine, but also to increase its shelf life. Nitrogen also plays a crucial role in packaging stability, particularly for ready-to-drink and single-use products, by reducing oxygen levels and reinforcing container structure.

Liquid nitrogen dosing systems offer a precise and efficient method for the controlled introduction of nitrogen into bottles prior to sealing, drastically reducing oxygen levels. These systems, like those offered by Chart Industries Inc. and Vacuum Barrier Corporation, enable simple, automated operation, contributing to package stability and integrity. What's more, they offer the flexibility to adapt to different products and containers, while providing significant savings through reduced production and packaging costs.

The choice of nitrogen storage method depends on production requirements and the size of the winery. Options ranging from bulk tanks to on-site nitrogen generators are available, each offering its own advantages in terms of cost and convenience. 

Safety remains a major concern in the use of liquid nitrogen, requiring strict measures to avoid the risks associated with handling this element. By implementing proper protocols and using gas detection equipment, wineries can ensure safe practices while enjoying the benefits of using nitrogen in their wine production process.
