Nitrogen gas is commonly used in wineries during different production stages such as sparging, blanketing and flushing. This to reduces enzymatic oxidation, bacterial growth and  preserve the wine from oxidation.

Winemaking and Vinification are delicate processes that require careful handling to achieve the desired quality and taste of the wine. Nitrogen is a versatile gas that plays a critical role in preserving the wine’s aroma and flavor during production. NOVAIR in-house modular nitrogen generators are commonly used in wineries to provide a constant supply of high purity nitrogen gas. Here are some ways nitrogen is used in Winemaking and Vinification:

  • Sparging: Nitrogen is used to displace oxygen from tanks, barrels, and other winemaking equipment. By removing oxygen, winemakers can prevent oxidation and preserve the wine’s aroma and flavor.
  • Blanketing: Winemakers use nitrogen to create a protective blanket of gas over the wine. This helps prevent oxidation and bacterial growth, which can ruin the wine’s taste and aroma.
  • Flushing: Nitrogen is used to flush out equipment and pipelines before and after use to remove any air or moisture that may cause oxidation or spoilage.

By using NOVAIR in-house modular nitrogen generators, winemakers can ensure a constant supply of high-purity nitrogen gas throughout the winemaking process. This reduces the risk of contamination and spoilage, resulting in a more consistent and higher-quality wine. With the right application of nitrogen gas, winemakers can produce a wide range of wines that cater to different consumer preferences.
