Argon and Nitrogen
Wine Preservation Systems
Inert gas wine preserver systems are becoming a very popular way to preserve your wine, and there is an increasing number of options available for you to use. The gases are colourless, odourless and tasteless, and leave a blanket over the wine, displacing the oxygen and therefore reducing the effect of the oxidation process. The typical gases used are Argon and Nitrogen.
Argon is completely inert and 2.5 times heavier than Oxygen. When it is inserted into the wine bottle, the much denser gas lays directly on the surface of the wine, creating a barrier between the much lighter Oxygen and the wine surface.
Nitrogen also settles over the wine and therefore creating a barrier against the oxygen. There are however mixed reports using nitrogen gas, with some suggesting that the nitrogen may have a detrimental effect, particularly on the less robust, older wines.
Some of the Wine Preservation Systems are:
Le Verre de Vin Systems (LVDV)
The Le Verre de Vin wine preservation system is probably more of a restaurant / wine bar system. They have a solution that they claim preserves Sparkling and Champagne Wines for up to 21 days by delivering carbon dioxide into the bottle. Sparkling wines rarely suffer from oxidation as they release a constant stream of CO2 which lies between the liquid surface and the air. What this system claims to do though is dramatically slows down the CO2 loss, ensuring the natural fizz stays locked in the wine.
Le Verre de Vin also offer a vacuum system for still wines that removes exactly the correct amount of air, and once again claim that this will preserve wines for up to 21 days.
Preservino also uses 100% Argon gas to preserve your wine. Their patented "Click and Pour" Wine Stoppers allow you to pour as many glasses as you like without removing the stopper or re-applying the argon gas.
Preservino also have a product called the VinoVault. It is a 14 bottle wine fridge with an argon gas dispenser built into it. The wines you are storing lay down flat, and it has a clear window for you to view the opened bottle you are preserving.
Private Preserve Wine Preservation spray uses a balanced mixture of three gases; Carbon Dioxide, Nitrogen and Argon to preserve your wine. Simply insert the tube into the neck of the bottle and spray. The wine bottle is then re-corked and stored upright to ensure the gas remains in and covers the wine. Each purchased canister applied correctly will give you 100+ uses.
ReServe wine preservation system injects pressurised pure Argon gas through an adaptor placed on the bottle to displace the oxygen, creating an airtight seal on the bottle for additional protection.
VinAssure™ Wine Preservation
VinAssure is an Argon dispenser system, allowing the user to inject pressurised argon gas into an opened bottle of wine before it is re-corked and stored upright in the fridge. It is an effective low per-use cost solution, giving around 700 fills per cylinder.
Wine Preserver
The Wine Preserver works a similar way to the Private Preserve system, and uses a nitrogen gas to displace the oxygen from an opened bottle.
WineLife Wine Preservation System
The WineLife wine preserver also works a similar way to the Private Preserve system, allowing the user to insert a tube into the neck of the bottle and spray an insert gas into the opened bottle.
VineyardFresh Wine Preserver
VineyardFresh Wine Preserver is another product that works a similar way to the Private Preserve system, allowing the user to insert a tube into the neck of the bottle and spray argon gas into the opened bottle.
Vinofresh
Vinofresh uses a combination of high-purity nitrogen and carbon dioxide that allows you to inject the gas directly into an opened bottle of wine, and they claim it keeps the wine fresh for up to 2 to 3 weeks. They also have a champagne adaptor for champagne and sparkling bottles.
Winesave™
Winesave is 100% pure food-grade argon gas contained in a consumer-friendly disposable aerosol can. You simply attach the hose to the nozzle, spray the gas into the opened bottle of wine and replace the stopper back on the wine bottle. Each can of winesave™ will give you around 50 saves, and is also extremely effective with Champagne and Sparkling wines.
Winesave is used at some of the world's best restaurants to protect their wines served by the glass. From Roka and Zuma in London to Marque and Quay restaurants in Sydney, winesave is the pure-argon solution used by professionals that consumers can now use everyday at home.
The Wine Saver PRO wine preservation system holds up to 5 bottles and can keep the wine fresh for up to 30 days. It is designed as a restaurant system where the wine is served by the glass. It works differently from the other options as it inserts gas automatically each time wine is dispensed from the bottle.
If you like to drink different wines each night Wine Saver now have a wine preserver solution for your home called Wine Saver HOME. This wine preservation system works the same as their Wine Saver PRO system, but it has a 3 bottle server rather than 5.
