Wine Preserver Refill Cartridge (2-Pack)

(Similar review left on actual preserver)This is my 2nd ZOS and cartridges as now I can open 2 bottles at once. It is cheaper and works better than my Coravin! I have tried all types of wine preservers over the past 30 years and i think i can finally stop looking. I have used my 1st ZOS since mid-December and it works great! I have stored the wines up to a week (I can’t wait any longer), but i’m sure it will keep longer. Based on my results, I have recommended the ZOS to all my friends with cellars as it is finally a great way to preserve a good wine with little effort.A few tips on usage for your consideration that I learned along the way:* As the instructions say, your main objective is to minimize The time the ZOS cartridge is out of the sleeve or out of the bottle that you are preserving.* When opening a new bottle, just pour the wine in glasses as you normally would and use the cork or a temp stopper until you have drank your fill.* Then remove the temp stopper and take the ZOS device out of the plastic cartridge and into the bottle quickly. You should store the wine (even reds) in the fridge with the Z0S device in it.* When you decide to drink another glass a day or more later, just take the bottle out of the fridge approximately two to three hours before drinking and leave the ZOS device in it.  When the wine is warm enough to drink, take out the zos device and put it back in the plastic holder immediately, to preserve the cartridge.* Finish drinking the bottle or store again in the fridge, again minimizing the time the ZOS cartridge touches the air.* Don’t forget the device uses batteries that are available on Amazon at about $.20 each-cheap. They need to be replaced every 3-4 months and you will know this when the device goes intermittent with colors and then no lights at all.Overall, it is great, so jump on it!

Works well, but the refills are very expensive. Probably better off with ART Wine Preserver. Does the trick for a fraction of the cost.

I've been a ZOS customer ever since they first released this product to market. While not 100% perfect, I just un-ZOS'd a bottle that I opened just before leaving for a week long vacation plus another couple of weeks. Three weeks later, the wine doesn't taste absolutely just opened - but at least 90% of the character is still there; which surprised me. I'm the only wine enjoyer in the home, and have always finished bottles within the week, and the ZOS performs well enough that I don't really notice any degradation. The involuntary three week experience gave pretty surprising, though very satisfactory results.So, all that said - for 90% preservation after three weeks, without the hassle of installing air blankets is a boon for me. I've tried many of those other systems, and yes, they work; but there's something that's a little off about using a spigot to pour your wine. The system which uses argon and piped stoppers was a step in the right direction: you didn't need a spigot but would have to blow some air back in after pouring. The ZOS? Pop the ZOS-cork, pour, and re-cork: the way it should be.

This product has saved many bottles of wine to be enjoyed over an extended period of time. I wouldn't use any other product. More importantly, they stand behind their product if there is any issue. So happy with this product and company. Would highly recommend!

You must continually renew the cartridges since one cartridge - one bottle. Cartridges available only via internet. Cannot recommend.

Works exceptionally well. I have not had a problem with bottle neck fit. It does seem loose when first inserted, but the seal tightens as oxygen in the bottle is removed. Only reservation is cost. Does not make much sense using on inexpensive wine.

I'll admit that I was a bit apprehensive about the claims of the ZOS but I can tell you that it does work. I've opened up a favorite bottle of Cabernet and was unable to finish it. I simply inserted the ZOS and let it sit for over a week and when I returned to it a week later the flavor was still there, the nose of the wine was still there. This is my second order of refills for the ZOS and I'm a fan.

Having used this system for a number of years, I find it to be simple and very effective in keeping open wine bottles fresh, right to the bottom.
