Wine Stopper by Cooking Concept

I discovered Cooking Concept's Wine Stopper while looking for a way to preserve the open bottles left-over from dinner parties. I would end up opening 3 - 5 bottles to pair with meal choices & guest preferences, but never finish all of the wines opened.

The device is easy to use, once you have finished your wine drinking for the evening, you follow this simple process:

1. Insert the nozzle of the Wine Stopper into the opening of the bottle.
2. Re-apply the product each time the bottle is opened.

About a week later, I re-opened the test bottle and tasted the wine. I then decided to see if I waited more than one week if the bottle would taste the same. I also wanted a true & fair comparison of my senses, so I opted for 2 identical bottles of wine at the same time, keeping one as a control.

The Test:

My conclusion

My conclusion is that for preserving wine for under a week this system is good. I would not suggest that you use it for any Long term storage (more than 5 days.) But my most common use cases, having left over wine from opening your 2nd bottle of the evening, it is a okay solution to keep the wine fresh until you have a chance to enjoy it again.
