How is Nitrogen Used in the Wine Making Process?
Problem: I am new to wine-making and I know nitrogen is used in the process, but I'm not sure how it is used.
Solution: 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:
- Pressurization: To avoid the supply of oxygen during pressing, the environment of the grapes is saturated with nitrogen.
- Inerting: Avoid the supply of dissolved oxygen to the surface of the must by nitrogen inerting.
- Flotation: Nitrogen microbubbles are injected from the bottom of the flotation tank
- Disassembly: The violent injection of nitrogen causes a restructuration of the cap without oxygen supply
- Assembly: Homogenize wines, glue or adjuvant without adding oxygen
- Inertage: Inert the gaseous skies of the tanks
- Transfer Tank: Avoid the supply of oxygen during wine transfers by oxygen inerting
- Filtration: Nitrogen injection in the musts or wines before the physical treatment to avoid a supply of oxygen
- Stripping: Consists of driving gas or volatile matter into the wine by nitrogen
- Deoxygenation: Remove dissolved oxygen by adding nitrogen
- Decarbonization: Remove dissolved CO2 by adding nitrogen
- 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.
- 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.
