Wine Preservation System | 100% Green Gas Based | Suitable For All Wine, Port, Sake, Cognac, Whiskey, Fine Oil & Vinegar 0.29 Ounce (Pack of 1)

As the title of this review implies, I don't use Private Preserve for wine. Rather, I use it to keep single malt scotch whisky from oxidizing. I have a large collection of single malts, and at any given time I may have upwards of 20 open bottles. While the affect of air on high-alcohol spirits tends to happen slowly, and some whiskies actually benefit from a bit of exposure to air, I have a number of higher end bottles that I want to preserve in that just-opened state.So my options were to open fewer bottles at once and finish them off in a shorter period of time (not likely) or find a way to prevent oxidation. Enter Private Preserve. While it is designed and marketed for the short term preservation of wine, it works amazingly well on scotch. A few quick bursts into the neck of the bottle creates a blanket of inert gasses on the surface of the liquor, which keep oxygen out and keep the scotch from oxidizing. I don't reseal all of my scotches when I open them, but for the ones I do, I use Private Preserve each time I pour a dram from the bottle, and it keeps the liquid inside just like it was when I first pulled the stopper.And it really does work. I've experimented by pouring a bit of scotch into another bottle and allowing it to oxidize, while resealing the original bottle. After a few months' time, there was a noticeable difference between the two, with the unprotected dram losing some of its aroma and tasting a bit flat compared to the one that was protected with Private Preserve.I purchase my first bottle of Private Preserve several years ago, and I'm still using it. Because it's filled with gas, it is impossible to tell how full the can is, so I just ordered more to be on the safe side. But suffice it to say, even with regular use, one can lasts a long time.

I love this product. It is so simple to use. It works great for any bottle of wine that is not finished. I used it on a bottle of red and had it in the fridge for a week. When I took it out and tasted it, the wine was perfectly fine. This is a great product for any wine drinker that does not always finish their bottles of wine. Note that when you get it, it will feel completely empty. This gives me some concern because I do not think I will be able to detect when the bottle is almost empty.My family uses the Vacu Vin vacuum pump and corks for their bottles but when I researched it, I found that it does not do a quality job. Any relatively cheap home bottle vacuuming system will not meet your preservation needs. Wine spoils due to oxidation with the air inside the bottle. A small plastic hand pump will not be able to do a good enough job of removing the air from the bottle. To create a good enough vacuum is actually quite difficult to do in the lab, so a small hand pump will not do the job. This Private Wive Preservation Spray works differently. It sprays an inert gas, that does not react with the wine, into the bottle. This displaces the air in the bottle and by corking it quickly, you prevent any air from oxidizing your wine. Enjoy.

I've tried many products to keep wine fresh. As I'm the only wine drinker in this household, I drink a glass, stopper it, and suffer through the remaining glasses, no matter whether I use a wine balloon or a pressurized suction stopper. I bought this product after reading an article in some online wine magazine. It works. Plain and simple. The first time I tried it, I was certain I'd done it incorrectly. I jammed a stopper in it, however and put it away. When I poured my next glass of wine a day or two later, instead of the sharp tang I've grown used to, the taste was smooth and favorable. There was no indication it had been opened a couple days prior.I just drank the last glass from the bottle, a week later, and, while it had a subtle tang, it's nothing like the taste I get using other products. A hearty recommendation from me!

Pretty cool item. I have used it for wine and notice it extends it by at least a week, but don't miss the other opportunities for this product. I've used it for saving a cut avocado for over a week. It probably uses a lot more of the product then a few small squirts required to cover the surface area of a bottle of wine. But I love the idea of stopping the natural breakdown of foods as well by replacing the air in a container with an inert gas.

This is the best way to preserve wine so far. I also used "Vacu Vin Wine Saver Pump with 2 x Vacuum Bottle Stoppers" before. It works but due to it's impossible to reach a high vacuum degree and keep in high vacuum, wine will still gradually oxidized.This nitrogen spray works much better. We all know nitrogen is heavier than air. So nitrogen can stay on top of the wine, preventing oxygen/air from reaching the wine. I drink a glass of wine almost every night. Normally I finish one bottle of wine in 4-5 days. Sometimes even longer because I would skip one or two days. Even after a week or so, the wine still tastes good.One bottle can also last long time. Mine lasts about 2-3 months. It just ran out so I just got a new bottle.

There is only one wine drinker in our house, so bottles empty at a rate of about one bottle a week. Since we started using argon, wines stay fresh all the way to the bottom of the bottle, whether that takes five days or a full week. No more worries about wasting wine!

This worked well for as long as it worked, which was a total of 5 times. After that, there was no more gas left in it. I contacted the company regarding this, and they said that I had the item too long, so they would not refund or exchange it. I had it about 6 months. It is an aerosol can, so it should still work after 6 months. I would not buy this again or recommend it. I have since purchased a wine vacuum pump and it works very well, is easy to use, and I don't have to worry about it running out of gas when I need it.
