Wine Preserver (Charcoal): Wine Saver, Saves Red and White Wine, Reusable Stopper Sealer, Seen On Shark Tank

Alright, I now had some time to test this out with several bottles. And I have to admit I am quite impressed. This is as good as it gets for the price. It is very easy to handle (one common complaint that it does not release the air quick enough is not true at all for the one I got). It is not 100% perfect but I would say almost on par with the inert gas in a bottle. The gas works a bit better as there is absolutely no air remaining while I feel the balloon is still leaving a few air bubbles on the side which are enough to oxidize the wine. However, the gas in a bottle has its own problems (e.g. you never really know when it is empty until you entirely spoil a bottle).Just as an FYI, this product is mainly for high quality aged wines. If you drink only recent vintages of <10 dollar bottles, go with a vacuum pump, they are cheaper and work perfectly fine with young wines (the problem with aged wines is that the vacuum pumps suck out all the flavor which is more delicate in aged wines).So all in all, I am loving it!

This thing works very well.Be sure to read directions. I, at first, thought it has to fill the whole empty space, and blew up the little balloon. It only has to squeeze against the walls of the bottle and choke air access out.It is a bit expansive for a bunch of plastic and rubber stuff. But if it takes you several days to finish a single bottle of decent wine, it pays for it self after a few bottles. And they have to use good quality food grade components. And the air valve has to work very well, not to allow much of the deflation.I just started using it after a long time since I bought it first. I leave the open bottle corked overnight, and it usually aerates well by next day. Without this device, and even when corked, the wine starts to decline in quality in just a day or so, and a couple of days it's quality becomes very poor compared to it's best. But with this device the wine keeps on going long enough that I can finish the bottle. Obviously if you can handle a bottle quickly, or have several drinkers in your household you would not need this device. But for the rest, it is a good option.

Actually, 1 star is not entirely fair. When it works, it seems to work pretty well...not 2 weeks in my case, but 3-4 days yes. BTW, I have tried and used any number for "preservation systems" Vacuum, so so; Private Preserv, a bit better; but the Air Cork seemed to promise better. And the concept is very good, but sadly, the implementation, the actual device is lacking in the necessary quality to perform its simple taskThe first balloon worked for 2 bottles, but on the third bottle, the balloon leaked....spoiling the wine. Unfortunately, the third bottle was the most expensive wine and was a total loss of 3/4 of a bottle of an excellent, expensive wine.I am now on my second balloon and am not sure whether to use it on any wine actually worth preserving.Good concept, poor quality of implementation. I doubt that I will purchase any additional balloons since at $9 per unit, and such a short life, it hardly makes sense. Perhaps the people who make this device will step up their game and provide a useful, usable device for $28. Otherwise into the garbage it goes!Maybe this crappy review will get someone's attention...one can hope!

Just got this, was pretty impressed by the whole idea. However, the balloon has deflated very quickly by itself several times in the last few days. It's too bad, I would not trust this to seal a bottle of wine laying sideways in my wine refrigerator (unlike some other wine vacuum kits I've owned). I can understand a slow deflating, but this was overnight. I'll give it a couple more days, but if it can't keep the pressure, I'm sending it back.Update - I switched the balloon to one of the others in the package and that seems to have fixed the problem. I was pleasantly surprised to get an email from the company offering a full replacement based on this initial review. Not needed in my case, but impressive customer service!

I don't drink a bottle of wine in one sitting, unless I have guest, but I still like wine. Sometimes, it takes me a week or two. I tried boxed wine for a while, but got tired of that. I saw this recommended on cooks illustrated so decided to give it a try. This keeps my wine good and its easy to use. The balloon has lasted about 6 months already. It seems to work better than pumping air out of the bottle and its cheaper than gas. Now, I can have a glass of wine in the evening and easily save the rest for later. I like this little gadget so much that I'm buying it as gifts (sometimes with an accompanying bottle of wine).Update - some of the balloons are defective out if the box. It's still a great product and hopefully the company will improve this. More balloons can be ordered off the company website. They are currently 4 for $8.
