How to Preserve Wine

We have a few tips for preserving wine that can be used independently or with ArT Wine Preservation. Check out Saving Open Bottles of Wine with Argon Technology to learn more ways to preserve wine!

How long does wine last?

Normally, open bottles of wine only last a few days once they have been opened. This is because the oxygen in the air reactions through a process called oxidation. With ArT Wine Preservation, you can preserve your wine for weeks, we commit to 14 days. Using the techniques below, in conjunction with ArT Wine Preservation, and you may join some of our customers that have preserved wine for over 6 weeks.

 

1) Refrigeration
Refrigeration lowers the energy in the bottle, thereby reducing the energy pushing oxidation reactions forward. That is because the higher the temperature, the faster the oxygen molecules will move and more often they will collide with the wine. More collisions lead to more reactions.
 
This does include red wines - although it should be noted that this was once considered faux pas. Red wine should be allowed to return to at least 55F (or producer recommended temperature) before consumption. Do NOT use heat as it may cause undesired reactions if localized heating occurs.

 

2) Remove sunlight.
Just like refrigeration reduces energy by removing heat, storing in a dark place removes the photo particles which add energy to the bottle and push the oxidation reaction forward.

 

 

3) Vibration Dampening
Shaking an opened bottle of wine is a debatably an effective manner in aerating a wine, because it makes for more collisions between the oxygen and the wine (though any wines with sediment will be well mixed…).
 
However - when storage and transporting wines that have been open you should avoid vibration and movement. This means don’t store it in places like your fridge door (or keep close to hinge of the door), above your garage, inside a car, etc.

 

4) Store upright
Leaving the bottle upright decreases the surface area exposed to oxygen compared to laying down. Lower surface area decreases the amount of molecular collisions between the wine and oxygen and therefore the rate of the oxidation reaction.

This may seem counter intuitive since unopened wine bottles are typically stored on their side. Keep in mind we are currently talking about already opened bottles of wine. In which case a reusable cork with argon is the absolute best method of “sealing”, as it reduces the surface area exposed to oxygen even after pouring.
