Nitrogen generators for the wine industry

In the world of winemaking, the pursuit of excellence and the preservation of quality are paramount. Therefore, winemakers are turning to a game-changing solution to enhance their craft: nitrogen gas. From preventing oxidation to controlling carbonation, nitrogen plays a vital role throughout the winemaking process.

How nitrogen is used through the wine making process

Nitrogen is employed at various stages of the wine making process:

 

  • Blanketing tanks and barrels: Nitrogen is used to create a protective blanket over the wine in tanks and barrels, displacing oxygen and minimizing the risk of oxidation.
  • Purging and sparging: Nitrogen is used to purge and sparge tanks and equipment, removing unwanted gases and contaminants that could affect wine quality.
  • Bottling and packaging: Nitrogen is utilized to displace oxygen in bottles before corking or capping, ensuring the preservation of wine quality during storage and transportation.

Benefits of using nitrogen in the wine making process

Using nitrogen gas in the wine making process offers several advantages:

 

  • Oxidation prevention: Nitrogen, being an inert gas, safeguards against oxidation, which can compromise the wine's taste, aroma, and overall quality. By displacing oxygen with nitrogen, winemakers create an optimal environment for wine maturation and preservation.
  • Carbonation control: Precise control over carbonation levels empowers winemakers to consistently achieve the desired effervescence in sparkling wines. This control ensures that each bottle of sparkling wine delivers a consistent and delightful experience to consumers.
  • Wine preservation: The replacement of oxygen with nitrogen in wine tanks, barrels, and bottles provides an effective barrier against oxidative reactions that can lead to wine deterioration. By extending the shelf life and maintaining quality over time, winemakers can ensure that their wines reach consumers in optimal condition, offering a delightful and satisfying tasting experience.

On-site nitrogen generators for the wine industry

On-site nitrogen generators provide wineries with a smart alternative to bulk or liquid nitrogen deliveries. By producing nitrogen on demand, winemakers can take control of their supply — cutting costs, reducing waste, and gaining greater flexibility across the production process.

 

  • Cost savings: Generating nitrogen on-site helps avoid the recurring costs of rented tanks, transport logistics, and evaporative losses linked to bulk deliveries.
  • Reliable supply: With nitrogen available whenever it’s needed, wineries no longer have to worry about delays or disruptions caused by delivery schedules.
  • Operational flexibility: Flow rates and purity levels can be adjusted to suit different stages of the winemaking process — from blanketing and purging to bottling.
  • Lower environmental impact: On-site systems produce only what’s required, minimising waste and eliminating the need to vent excess gas — a common issue with third-party supply. The reduction in transport also cuts the overall carbon footprint.
  • Improved safety: Nitrogen generators remove the need for high-pressure cylinders, reducing associated risks and simplifying handling procedures.
