As both red and white wines are subject to oxidation, restaurants have begun to explore better ways to preserve their wine bottles. Preserving your wine with nitrogen or argon can add weeks to the life span of a bottle of wine by getting rid of the oxygen. As some wine drinkers prefer only one or two glasses per visit to your restaurant, many restaurants have also begun to explore better ways to dispense their wine. If you have been thinking about a wine preservation system, or a wine dispensing system for your restaurant, you will need a nitrogen or argon supply. As argon and nitrogen are both inert gases, they replace the oxygenated air that eventual spoils the taste of the wine. Metro Carbonic can supply you with highest quality beverage grade nitrogen and argon need for most wine preserving and dispensing systems.
