Wine bottle preservation — Vacu Vin, argon & nitrogen, Eurocave & WineKeeper systems
If you would like to keep an open wine bottle for more than a day or two, there are some things that you can do to maximize your wine preservation. Re-corking a bottle of wine and putting it in the refrigerator will work for a day or two, but there are some more robust methods.
Vacu Vin wine saver systems
If you would like to keep the wine longer, consider a Vacu Vin wine saver [view at IWA or Wine Enthusiast]. This system has been around for more than a decade. If properly used, you can preserve your opened wine for up to a week. The idea is pretty simple — you just put in a Vacu-Stopper and pump the air out of the bottle with the (appropriately named) Vacu-Pump. Since the oxygen has been removed with the air from the bottle, there won’t be any spoilage due to oxidation.
Bottled argon and nitrogen
If you don’t want to use a Vacu Vin system, another easy and low cost choice is using bottled argon or nitrogen [view at IWA or Wine Enthusiast]. The basic idea is the same as with the Vacu Vin — remove oxygen from the bottle — however the method is different. Spraying the argon or nitrogen into the bottle will displace the oxygen-containing air in the bottle. To use these products, spray a two-second burst of gas into the opened wine bottle and quickly replace the cork.
EuroCave wine storage & dispensing systems
EuroCave wine storage systems [view at Wine Enthusiast] hold two bottles and will chill and preserve wine for up to 10 days. Uncorked bottles are placed inside and kept fresh with a vacuum system, so there’s nothing to replace. There are two compartments with variable temperature settings, which allows you to keep red and white bottles at different temperatures.
WineKeeper wine storage & dispensing systems
WineKeeper wine storage systems [view at Wine Enthusiast] preserve up to four to eight bottles of opened wine. As you dispense wine through the spouts, the WineKeeper keeps the bottles filled with nitrogen to prevent oxidation. As with the EuroCave system, the wine is kept at proper serving temperatures. The units come either in Mahogany or Oak facing, with a glass display door.
