Nitrogen Generators Aid in Bottling Wine

Nitrogen Gas from a Nitrogen Generator is used in wine production in several ways.

Sparging involves the introduction of very fine gas bubbles to help remove dissolved oxygen or CO2, or sometimes to add CO2.

Blanketing attempts to maintain a Nitrogen Gas layer above the wine surface in order to minimize the contact of air with the wine. To prevent the growth of aerobic microorganisms on the wine surface, the O2 concentration must be reduced from the levels found in air to less than 0.5% on the wine's surface.

Just prior to bottling, air must be flushed from hoses, filter housing pumps, and the fill bowl by using a displacement
gas such as Nitrogen, since the amount of oxygen in wine can influence wine quality, stability, and longevity.

Nitrogen is preferred for these applications because it has a very low solubility in wine. It is also available very economically via a Nitrogen Generator, which makes Nitrogen out of air and eliminates the need for a gas supplier, and for storage of bottles and tanks of liquid Nitrogen.

Nitrogen Generators are also convenient for wine makers, because Nitrogen is made as needed, and the Nitrogen requirements for wine bottling may vary at different times of the year.
