ArT Wine Presever - Wine Presever Gas for Wine, Whiskey, and more, Argon Wine Presever for Wine Preservation, Argon Gas with Wine Bottle Stopper, Preserves White & Red Wine Up to 30 Days

I had previously used the wine preservation systems that make you put a small cartridge into a gizmo, then shoot gas into the bottle. They got used up SOOO fast, the value was low. BUT, this works awesome! One can of this can handle dozens (more?!) of partially-consumed bottles of wine. Just shoot in the argon for a second or two, re-cork your bottle, and voila - you've "capped" the wine so the oxygen doesn't keep oxidizing the wine. Stand the bottle up, lay it down - just doesn't matter (though the latter takes a bit more argon). Your wine stays fresh for days - either in your refrigerator, or not. Works no differently on expensive, or inexpensive wines; it preserves them all equally well. I've switched to this, happily.

To sample many different bourbons and ryes from my collection, I don't tend to drink through a given bottle over a period of years. Due to that delay, air can take its toll on the taste and specifically the original VIBRANCY of smell, palate and finish. The best way around that is to use an inert gas to displace as much of the bottle air as possible (or perhaps a great vacuum but that's hard to maintain). If you weren't paying attention in chemistry, an inert gas ("noble" gas) like argon has its electron valence (outer "shell") full and therefore doesn't need to pull electrons from other atoms and won't freely give away it's own in an effort to achieve a more stable, lower energy state...hence, it doesn't interact/react with or change what it contacts and is "inert." Oxygen is in the air and is of course very aggressive (its outer valence is 2 electrons shy of being full), so since it's aaalmost there, it's very aggressive and it's not what you want playing with your whiskey (or wine, etc.) over an extended period. If you go through a rotation of just a few bottles at 2-3 drinks most days before opening something else, when it comes to whiskey, you'll be fine. Wine drinkers know they need to finish their bottle relatively quickly and it comes down to electron valences. In my case, I might not come back to a whisky bottle for 2 years or more. It doesn't mean I don't like it. It could, but it could mean I want to save/savor because I'll never find that bottle again or just want to try other things for a while. If I don't use the argon, which is how I started because the web is full of information saying you can keep your bottles with a good seal, in a cool place, out of the sun, forever practically, then the flavor dulls, and eventually gets pruney and then vinegary. At that point it's a "drain pour." So I've moved to this brand which has more argon concentration than another brand I've used. Nitrogen is better than oxygen but is not fully inert. I'll leave the debate on degrees of relative interaction and benefit between argon and nitrogen to others. For now, my whiskey and therefore my "investment" and enjoyment benefit from the use of argon and this product. I won't go without it.

Works to effectively preserve wine at a fraction of the cost of some other systems. Would be nice to have a second stopper provided as I sometimes have two bottles open.

So far, so good, 36 puffs and no end in sight. Will see how far this bottle goes, shorter puffs on next one to test. This product works as advertised. Used it on all fill levels in bottles, with last smallest (100ml) amount after 5 days. No signs of degradation. Wines were pinot noir and chardonnay from vintages 2012-2016. This is a more economic solution to manage consumption than a Coravin, and frankly a Coravin takes counter space we don't want to donate. Also, the Coravin wine would be at ambient temperature rather than serving temperature (PN slightly above "cellar" - 60ish+, whites 10 degrees cooler). (Frig is too cold for red or white to drink, OK to store a treated bottle upright, remove and let warm. If a red is "flabby" at 75 degrees, there is a reason - too warm. If a white doesn't taste good warmer than frig temp, it isn't a well made wine.) Since we're not going to AC the house below mid 70's, the Coravin doesn't work. Maybe it could for you. In the absence of a "unit" Ar bottles work well. Argon is an inert gas, heavier than air so gravity is your friend (unlike old age). Not much is needed. Please be aware diffusion is a physical process that will eventually cause oxidization even for Argon treated wine because the top of the bottle still holds 21% oxygen (along with .93% Argon). For the technically inclined you can probably find the diffusion coefficients and do the arithmetic on the integrated diffusion equation to calculate a concentration curve. (Can't offer any help. No technical books.) I will be curious to see how Ar does with an old wine. I doubt it will be perfect because a 20+ year old wine opens in oxygen, fades over time. If it is enough to preserve a top bottle for 2 days, it wins. August 2018, forgot to update ... Got about 105 puffs from one can (no fewer, could have been a few more). This makes it a fair purchase at the listed price. Nothing has changed since I wronte this. It does keep fine wine for days. You should open the bottle, pour what you wish, spray Ar, recork without letting significant time elapse. If another glass is desired, repeat. Don't wait to apply the Ar to drink both (or however many) glasses. To the ArT team: Go Boilers!

This is more expensive than the other spray can preservers, apparently because it is pure food-grade argon. I don't know if the superiority of pure argon is marketing or truth (if you do a search on the subject you wind up with conflicting results) but for the small difference in price I figured I would try this one. The can arrived in a couple of days, in good condition, and it is really easy to use. Just spray into the bottle with the wine you want to preserve for 2 seconds, insert the tight-fitting cork that comes with the can, and put it in the fridge. Now, I only use this to preserve the wine until the next day so I can't speak to its longevity but it appears to do the job. Since using it I haven't had any wine that has suffered and for the most part day 2 tastes like day 1. I don't think it is going to be exact because the wine starts reacting with air as soon as you open it and you can't tell what sort of changes might take place but for me as I said, day 2 is pretty consistent with day 1. Prior to this I was using a device that vacuums the air from the bottle but this ArT product seems to work a little better. I wrote to customer service to ask just how many 2-second sprays to expect from a can and the owner himself wrote back pretty quickly to say there should be 50. I think it's worth it and plan to keep using it.

I like the argon gas contribution to increasing the storage time of my open wines. With that said, only putting 1 dispensing straw in with a case of cans creates some challenge.

I have used a different brand (not using argon) for a while, and it is sort of mediocre. Helps for a day or 2. But this really works well. It seems to keep wine in good shape for many days after opening. BUT--I have bought 3 bottles. One worked great. The other two have had problems with their valves. I'm not sure if the gas leaks out, or if the valve does not open or close reliably, but the most recent use there seemed to be little pressure left after the first time. NOTE: I am well aware that the can seems light and I am familiar with the hissing sound when it is working, so this is not the issue. I would give it 5 starts except for this. Re-review 12/25: I’ve upgraded the stars to 5 (how often does that happen?) These guys give top-notch customer service. I complained to them about the broken valves (from above, a few years ago), and they not only said they would work on fixing it, but they sent me a couple bottles replacement. This month I ordered another box of them and UPS was supposed to deliver on Friday. It went out for delivery on both Friday and Saturday but never arrived, and then nothing more in the tracking. I contacted the seller, and again they responded quickly and they were very willing to give me a new box if it did not come in a couple more days. I’m not sure if they talked to UPS, but it appears that UPS made a special trip to deliver my ArT the same evening. UPS—hmm. ArT— GREAT.

This stuff is great! When you get it you will think the bottle is empty, but it is not. It is full of lighter than air Argon gas. It lasts for over 100 bottles. If you figure you pay say $15 to $20 per bottle and it saves half the wine in the bottle then that is a savings of $750 to $1000 per bottle of this stuff. The biggest thing to me is I no longer have to think "can I drink this entire bottle of wine tonight". You can open a good bottle of wine and drink one glass, spray this stuff in the bottle, put the plug in it and put upright in the frig and then go back to it in a month and it is still good. Just like the bottle has not been opened. It keeps the wine as it it had not been opened. I have given a lot of bottles of this stuff to friends. It is amazing. This is a good gift idea to friends who drink wine. Instead of giving them wine they will not drink or turn their noses up to, give them this. The more expensive the wine they drink the more they need it. It really works much better than the vacuum system. The vacuum system only keeps the wine for a few days, this keeps the wine good for months. Tell them when you give it to them that they will not longer not open a nice bottle of wine because they cannot drink it all in one sitting. They can open a nice bottle, have one glass for dinner and save the rest for next week or next month.

I sprayed the bottle I received into a small coffee mug, for about 17 seconds. I then lit a match and placed it inside the mug. The match stayed lit. Shouldn’t the argon put out the flame? In the companies YouTube video the match flame is extinguished by the argon. Makes me think I got a can of compressed air and not argon

I tried two wine preserver: this one (argon based) and another (nitrogen based). This one (argon based) is twice the price and does not work well at all...My wine was really oxidized after just a week

I contacted the manufacturer and was told this is pure argon that can be used to store chemicals. I have serious doubts about it being pure argon. I used this stuff to try and prevent oxidation of amine compounds and they formed the CARBONATES after a while (not much but its there). This is probably ok for wine, but don't try and use it for chemical storage.
