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 use this product to keep my whiskey bottles fresh and it works wonderfully. It's not widely known, but whiskey also oxidizes over time. The more air space in the whiskey bottle, the more rapid the oxidation. My wife also uses ArT to keep her white and red wines fresh for a few days. I always have a stock of ArT cans on hand.

A four pack has easily lasted me a year of casual wine consumption. I hate wasting wine from oxidation and also don't want to drink a whole bottle every time I can a single glass of wine, this product is simple to use and highly effective.

Works well for preventing oxidation in homebrews but there are cheaper alternatives in the market

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 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.

Did not last for as many uses as similar product

We use this frequently, on our third can. Would highly recommend.

I used this to "Argon Purge" an NVG optic that I assembled. Usually they are nitrogen purged but Argon is as inert as nitrogen and a little easier to work with. It is heavier than air so spraying it in pushed all the air out the top and I sealed it. Not as good as factory, but better than not purging it at all.For the price, excellent. To get a NVG purged is about $100+

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 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 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.
