How is nitrogen used in the wine making process?

You are new to wine-making and know nitrogen is used in the process, but you're not sure how it is used?

Pneumatech Wine
Nitrogen is critical in the process of wine-making during multiple steps of the operation, and mostly used to remove or keep oxygen out of the process. Pneumatech's line of on-site nitrogen generators are ideal for every step in the process including:
  1. Pressurization: To avoid the supply of oxygen during pressing, the environment of the grapes is saturated with nitrogen.
  2. Inerting: Avoid the supply of dissolved oxygen to the surface of the must by nitrogen inerting
  3. Flotation: Nitrogen microbubbles are injected from the bottom of the flotation tank
  4. Disassembly: The violent injection of nitrogen causes a restructuration of the cap without oxygen supply
  5. Assembly: Homogenize wines, glue or adjuvant without adding oxygen
  6. Inertage: Inert the gaseous skies of the tanks
  7. Transfer Tank: Avoid the supply of oxygen during wine transfers by oxygen inerting
  8. Filtration: Nitrogen injection in the musts or wines before the physical treatment to avoid a supply of oxygen
  9. Stripping: Consists of driving gas or volatile matter into the wine by nitrogen
  10. Deoxygenation: Remove dissolved oxygen by adding nitrogen Decarbonization: Remove dissolved CO2 by adding nitrogen
  11. Barrel Racking: The injection of nitrogen at low pressure in the gaseous sky of the barrel will allow the evacuation of the wine by the cane
  12. Bottling: Avoid dissolved oxygen in wines and headspace by nitrogen inerting

The purity of the nitrogen during wine-making can range from 99.5% to 99.9% depending on which stage you are at in the process. Pneumatech offers a full line of on-site nitrogen generators that offer various purities for all applications including wine-making. You can browse our full line HERE.
