Private Preserve 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.

My wife doesn't drink wine so a bottle keeps me in wine for four - five days. I've tried vacuum pumps of all sorts, with varying degrees of disappointment. The argon gas in this canister works great. Argon itself is inert and doesn't pose any health risk to us, (unless you fill a whole room displacing the oxygen). The heavier than air Argon makes a blanket layer between the wine and oxygen. No oxygen, no oxygenation! Keeping my wine for 5 days is never a problem. This is also a lot easier to use than the vacuum pumps. When the can gets low, the pressure is reduced and you can hear the velocity of the gas slow down, order your next bottle when you hear the significant pressure change. After the pressure changes, I still use it several times. This pays for itself because I'm never dumping the last glass of wine due to the wine going bad. I did that frequently with the vacuum pumps.

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.

This is what you need to preserve wine after opening and storing for x? amount of days. Gas will cover the wine to prevent oxidation. This is the same process that protects wine must during fermentation. You will not preserve 100% of the wine aromatics but the wine will not spoil. I use the rubber bottle stoppers that came with my Vacu Vin pump. I do not use my Vacu Vin any more. I found my wine oxidizing after 24hrs or less with the vacuum pump method.

Love this stuff

I bought this product primarily to preserve select bottles in my scotch collection. After dabbling in homebrewing, I also found it useful to prevent oxidation in mead during aging in less than full containers. My heavily peated scotch in particular benefited from this stuff. Being a product of incomplete combustion, the peaty smoke gets oxidized more easily. Commonly this changes the flavors to a characteristic "cigarette ash" flavor and masks much of the complexity. In using Private Reserve, I've been able to completely avoid these off flavors in my less oft consumed peaty single malts. Pros: Easy to use and effective at reducing the effects of oxidation in wine and whiskey. Doesn't alter the nose or taste of beverages. Cons: The average person will get much less than 120 uses out of a canister. I got perhaps 60, 70 at most. That being said, it's only worth gassing bottles that will be sitting partially empty for a month or more. Particularly for spirits, if you're going to finish the bottle within a month or two, don't waste the gas on it.

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.

Been using this product for over 20 years. I’m a very experienced wine lover and former collector (I drank my collection after the recession of 2008!). Anyway, this is a great product that really works. Just have to follow the directions. It’s pretty easy. You will save the cost of this product after one or two bottles of use. Most wine left untreated, but refrigerated after opening, will last for 1-3 days before a noticeable decline in quality. Treated with this gas and kept in fridge or cool place will extend the shelf life for at least 5 days. This one’s a no brainer.
