When you open the bottle at home, oxygen enters the bottle and begins to interact with the surface of the wine. This interaction is called "oxidation" and changes the flavor profile of the wine over time. As the wine oxidizes, the flavor changes from a more desirable "opening up", to a neutral affect, and then to a degradation of the flavor. This curve goes all the way to the undesirable point of the wine tasting and smelling like vinegar. To learn more about this, check out our article on "Why Do Open Bottles of Wine Go Bad?"
Can You Stop Wine from Oxidizing?
Yes! You can stop the process of oxidization. You can accomplish this through lower storage temperatures, removal from direct sunlight, and preventing oxygen from touching the surface of the wine. Unopened wine bottles stored in a wine fridge or wine cellar can accomplish two of these things.
However, when you cork the bottle, you're allowing air into the bottle and the oxidization process begins.
To stop this process and keep your wine tasting fresh, use a proven effective wine preserver. 100% Argon based wine preservation systems have proven to be the most effective method, with argon used in Coravin, Napa Technologies, VineyardFresh, and our own Silvadore Wine Preserver.
Press and release the nozzle twice to create two bursts of 1-2 seconds each. This puts the colorless, odorless, tasteless, 100% food grade argon into the bottle.
Leisurely re-cork the bottle - no special stopper required. Argon is heavier than air and settles onto the top of the wine to form a protective layer. Think beautiful mist nestled on top of a smooth lake.
This protective layer remains effective until the next pour.
Store the bottle upright, in a cool dry place
Reopen the bottle, pour another fresh tasting glass of wine, and repeat
That's all you need to know. Simple, inexpensive, effective.
How Preserving Wine at Home Can Change Your Life
Preserving open bottles of wine let's you do all sorts of things differently. By being able to enjoy a single glass of fresh tasting wine from any bottle you have changes how, when, and with whom you enjoy wine.
If you want to preserve the fresh taste of your open bottle of wine for another day, don't suck. Create a 100% argon barrier to stop the oxidation, and place your bottle in a cool and dark place. Just don't trust the "click"...
