Repour Wine Saver, Wine Preserver and Stopper Removes Harmful Oxygen from Your Wine, Simple and Effective, Glass, Multi-Colour, Pack of 4

These work great! Easily saves wine for up to 2 weeks if stored in a cool, dark environment. (Have never had it any longer) Love being able to enjoy the wine over a period of time to see how it evolves. Brilliant!

Really good and works. Possibly takes some nose away but the wine keeps really well and I’ve used it to keep wine a week so I can open couple of bottles, have a glass or two of each then next week go again. On half decent or wine costing a bit it’s well worth the £2 a stopper. They can only be used once but you can use a few times on same bottle limiting stopper back in but I’ve used them as a one shot to preserve. Brilliant and just what I needed.

Incredibly, this really works. I've used these multiple times now and am extremely happy with the results. Make sure to remove the little silver sticker at the bottom of the "cork," ensure it is firmly placed in the bottle top and it will keep wine fresh for a week! I have some nice bottles of wine that I previously hesitated to open because I was not going to drink the whole bottle in a sitting, now I can enjoy a nice bottle over the course of a week with very, very minimal loss of quality. Game changer for about $2 a bottle!

The Repour system keeps wine fresher than the manual vacuum pumps. The lower the fill level of the wine, the faster the oxygen absorber will deplete itself. It's not a miracle worker, but it does the job if you're looking to enjoy a good bottle over a few sessions. Ultimate efficacy depends on how many times you open the stopper and how much air is inside the bottle each time you put the stopper back in.

I love these, they're really handy and do what they say they do. It would be even better if they were reusable, but I'm hoping that might be an option in the future!
