Repour Wine Saver - Wine Preserver and Stopper, Removes harmful oxygen from your wine, simply and effectively,Indigo Blue,10 Pack

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!

I saw that these have been lab tested, but I decided to do a bit of a field experiment of my own. I figured I’d pour one glass, install a repour, pour 2 glasses the next week (to get more air into the bottle and really test this thing), then wait two weeks and pour a 3rd glass, and wait 1 more week and pour the last glass left in the bottle. A 28-day test. OK, I don’t have a Ph.D. in anything much less in Chemistry, but I was able to enlist a NASA scientist friend who has a Ph.D. in Planetary Science to vet my protocol, supervise the experiment, and of course… to help me taste the wine! lol. In the interest of truly furthering science, we selected a delicious 2013 Napa Valley Cabernet Sauvignon to be our test subject. We chose a 4 week duration because the probability that any bottle of wine would make it that long in either of our households without being fully consumed approaches zero. Thus, if confirmed by tasting, the probability that a single repour would truly last an entire bottle with no degradation, in our households, approaches 1. Results First Pour: Delicious. After 1 Week - 2 glasses: Delicious After 3 Weeks - 1 glass: Delicious After 4 Weeks - last glass: Delicious We noted at each taste that the wine required a little time to open up, just as the first glass did. We thought the last glass may have taken a little less time to open up, but because when exactly it has “opened up” is subjective, and because an unprecedented 4 weeks had passed since the bottle was opened, we could not rule out expectation bias. Regardless, the wine did not deteriorate in flavor, color, or aroma - at all - from beginning to end. Conclusion: These things are bloody brilliant! Not only have I not wasted any wine since I got them, but they’ve made it possible to pair wines better. For example, on a lazy Saturday I could have a glass of Viognier with brunch, a glass or two of Rosé in the afternoon, a glass of Pinot Noir with a snack later, and then a glass or two of hearty red with dinner. I could never do that because it would be 4 leftover bottles I’d have to either drink up on Sunday - and I tend not to drink on work nights - or dump out. The best I ever got out of wine preserver sprays was two days, and still with some noticeable change in flavor. With these, keeping the opened bottles until next weekend and well beyond is possible! No more spraying wine preserver in the bottles and keeping them in the fridge only to have them croak after a couple of days. At only a buck each for 72, even saving half a bottle of $5 plonk saves $2.50 worth of wine so I'm $1.50 ahead. The savings go way up with more expensive wine. I may not know how to brew fame and bottle glory, but now I can put a stopper on death ;-) 100% recommended. Go ahead and buy 72 of them for a buck each - they work! Hmmm… Now that I think of it, that should be his motto: Repour. Put a Stopper on Death. haha

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.

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.

Love it! Keeping my wine fresh after opening! Great!
