I have used these wine stoppers for about 3 months. The stoppers are used in conjunction with a pump that removes air from the wine bottle. My wine has stayed fresh for 3 weeks or more using these stoppers. Can't ask for anything more.

Was trying to replace some bottle stoppers I've had, however, these were not quite as good a quality.

Wine Stoppers really work, just listen to the popping sound when you open a bottle of wine that has been sealed with a Vacu Vin Wine Saver.

When shopping for these replacement corks, I was trying to find a review to confirm that the new style corks work with the old style pump. I took the chance that they would, and happily found that the new design corks work with old design pump.

These are great! However you NEED the VacuVin PUMP to make them use. Don't try to use them without the pump as they will not stay in secure, and will not keep your wine fresh. You're better off using a piece of plastic over the bottle if then to just try ordering these corks without first having the pump.

With the pump these work great and are necessary as extras. Just make sure you take them apart and wash them in hot soapy water before using.

Also, both times I ordered these extras they came in a plastic zip lock bag with an amazon label. So I think Amazon must get a batch of them in and seperate them by hand.

The Vacu Vin system is the best available. Pay attention the next time you're in a bar--they're using these, too! My husband doesn't like wine and these stoppers enable me to have a glass when I want it without feeling compelled to chug the entire bottle at once. :)

These are a little different than the first ones I bought, but work great. Use for wine and large bottles of Belgian bier.

Were have all your stoppers gone? Mine whent with my son. If you need this stopper you all ready know it's good.

These work great, as another reviewer has said, though - they don't make the wine last forever. You have to have properly set expectations and handle the open wine carefully, sealing it quickly. Also if you leave the wine out of the refrigerator, it will spoil, the simple act of opening it has set the clock in motion. You are merely trying to slow it down. Certain wines oxidize/spoil more rapidly (or at least develop that metallic nastiness of oxidized wines) than others.

The only better 'systems' are:

1. Glass marbles. Whenever you take out some wine, leave the bottle open ONLY LONG ENOUGH to pour a glass, then top it off with clean glass marbles, right up to the top and recork it (using the vacuvin if you have it for double security) and refrigerate it.

Clean marbles? First steal them from any handy 10 year old boy, then hide them in the silverware basket of the dishwasher and leave them there. Your marbles will be safe from the 10 year old, and clean when you need them. Voila!

2. Never open the wine. Not really an option ;-> Particularly with 10 year old kids around...

Cheers!

I am guessing that there is some other part that is necessary for these to work because they do not work.

Have used this effective and inexpensive product for years. Keeps the balance of a bottle of good, even older, red fresh for 1-2 days. White in the refrigerator a couple of days longer. Cork as soon as possible after the first day's pour. A simple economical alternative to a nitrogen/inert gas injector.

These are wonderful to use. They make a huge difference in keeping wine fresh and sealed.

I've had this product for 2 years now, and it's great for those of us who don't drink whole bottles of wine in one sitting. the only drawback is that the corks are easy to lose, but they're cheap to replace, and they really help make your wine last longer!

Had an earlier version of this product and the redesign works easier. My wife even likes this better.

You can't have too many wine stoppers, especially after a party where you've have several types of wine available.

They are very reliable. Never had one leak. I couldn't live without them.

Work well to keep wine fresh! Always need extras on hand.

I recently bought the Vacu Vin kit from the local grocery and it worked fine. The only problem was that the kit contained only one stopper. I use the extra stoppers for multiple, opened wine bottles.

The excess air is removed and the wine stays fresher longer.

These things work great to preserve your bottle of wine! My husband & I don't usually consume an entire bottle of wine in one sitting, so we started using the Vacu Vin wine savers, & now we open several bottles, reds, whites, whatever & don't worry about wasting the wine because it keeps for so long now!

Looking at the reviews of this an other Vacuvin products, you see reports that are deeply contradictory. It's interesting that there is such a divergence of experience with such a simple product. The ideas behind Vacuvin are pretty simple.
First, air is the enemy of an open bottle of wine. Bacteria in the air want to turn alcohol into vinegar. The air itself oxidizes and dulls the taste of all but the most robust wines.
Second, you can remove some of the air with a simple pump and thereby slow down the rate at which wine deteriorates.

Why then, do we have both no-star and five-star reactions to this product?
Maybe the biggest source of disagreement is expectations. Vacuvin slows the deterioration of wine in the bottle, but it doesn't stop it.

Another possible reason for all the disagreement might be a question of temperature. The biochemical reactions that kill your wine are temperature sensitive. They proceed faster when the wine is warm and slow down when it's cool. Putting a pumped-out bottle in the refrigerator or wine cooler will slow down the spoilage processes and make Vacuvin more effective.
A third issue is the way the wine is handled before the Vacuvin plug goes in. If wine has a lot of air dissolved in it by being poured from decanter to bottle, there's no system that will keep it fresh.

Small, ugly & perfect. If you don't buy these now--you'd best put them on your wish list!

I had the opportunity to use these this past weekend and they work exactly as described. Wish I had known about them earlier.

This vacuum pump system works well enough to keep a bottle of wine good for up to a week or more. Having more than one stopper on hand is useful when you don't want to drink the same wine every night or when you live with someone whose preference differs from yours.

Having a set of extra stoppers is especially useful in the aftermath of a house party, when you may have several half-empty bottles of wine left over.

These stoppers last very well. They don't dry or crack, even when washed frequently in the dishwasher. It is convenient to have a stopper available even when the others are waiting for the dishwasher to be run.

These work quite well. With the pump, it's the perfect solution for those of us who only want one glass at a time.
My wines have, for the most part, stayed 'fresh' when using this system.

I've used this system for years, and it certainly extends the life of open wine. I have not left open wine at room temperature so I don't know whether that works. The seals on the stoppers eventually wear out so it helps to have extras. I consider the claim that it will keep wine for up to two weeks to be overly optimistic.

I have had this system for at least 2 yrs and it has worked very well for me. I find that it keeps the wine fresher for a longer period as long as it is properly refrigerated. I cannot attest to nonrefrigerated wines using this system as I always refrigerate my wine after opening.

This is a nice product to have especially if you enjoy opening more than one bottle of wine at a time. The wine keeps in the fridge very nicely with the help of this item!!
