We’re frequently asked: “What’s the best way to save half a bottle of wine?”
Using a special gas that wine bars use is obviously out of the question, so next we suggest pouring the unused amount into a smaller bottle. What this does is attempt to reduce the amount of oxygen that can surround the wine. As this method isn’t perfect and requires a few differently sized bottles, the people at Wine Shield have developed a disc that slides into your original wine bottle and sits on top of the liquid forming a barrier between the exposed wine and the bottle’s oxygen, thus delaying the Oxidation process which eats away at your wine’s freshness.
We found that the product does indeed help. Swirl the bottle a few times after dropping the shield in to get it to lay perfectly flat. Continue to use a cork or screw cap and refrigerate the bottle as you normally would.
