How Does Repour Work?

Oxygen Absorption is the Key!

  • Repour is designed around a standard 750ML bottle of wine under the assumption of 5 5-ounce pours.
  • Material inside the stopper removes all of the oxygen from the air above the wine and from the wine itself, completely stopping the degradation process.
  • As Repour works to remove the oxygen, it is also depleting its active ingredient - which is why its use is not unlimited.
  • Other wine preservation products use air displacement, which reduces the oxygen but doesn't eliminate it, so they will keep your wine fresh for a few days at most.
  • Repour will keep your favorite wine fresh for up to two months.
"We tested Repour on two bottles between one and two-week intervals, and there was no detectable signs of oxidation or change. We genuinely love this product and recommend it to all levels of wine lovers." The Wine Guys

Simple steps to fresher wine:

  1. Each Repour stopper will save one 750ML bottle of wine when taken glass-by-glass over an extended period.
  2. When the bottle is empty, dispose of the stopper and start again with a new one on the next opened bottle.
  3. Repour works so well, the wine may need to "open up" again when you return to pour another glass.
  4. Keep Repour in the bottle when not pouring wine. Extended exposure to air outside of the bottle will lessen its ability to preserve wine.
  5. When using Repour, do not store your wine bottle on its side. Doing so will render Repour ineffective.

Frequently Asked Questions

  • Can I use Repour for more than one bottle? Repour was designed to absorb the oxygen from one 750 ml bottle of wine, enjoyed glass-by-glass. If you move it to a second bottle, it may lose its oxygen-absorbing capacity before you finish the bottle. As a rule of thumb, when your bottle is empty, so is Repour.
  • How does Repour compare to vacuum pumping my wine? While a vacuum pump can slow the degradation of your wine, the best-case scenario is that it's only good for 2 or 3 days at most. If you properly "pull" a vacuum on the bottle, it can also pull out the wine's aromatics and flavors - which do not return. Even if used correctly, it only creates up to a 75% vacuum, which still leaves a lot of oxygen in the bottle to cause damage. Leakage is another consideration, and some tests also show the seal on the vacuum can be completely broken within 12 hours. Air is made up of 21% oxygen, and Repour creates a 21% vacuum inside the bottle which means virtually zero oxygen is present to damage your wine.
  • Can I lay a bottle on its side when it has a Repour in it? Since air needs to pass through the sachet in order for the stopper to work, the introduction of moisture from laying a bottle on its side will render Repour ineffective. There is nothing harmful in the sachet, and nothing enters the wine, so there is no danger in drinking it. Depending on how long the bottle has been without Repour's absorption capabilities though, there may still be oxygen in the bottle which has degraded it.
  • Does Repour change the taste or aroma of the wine? Testing on red, white, and rose wines by winemakers, sommeliers, and other wine professionals indicate both taste and aroma are unaffected by Repour's technology.
  • Do I need to let my wine “open up” again once I return for another glass? Because Repour so effectively reduces the oxygen from the air above the wine and from the wine itself, we have found it can be helpful to allow a moment for the wine to open up again when returning for another glass. A simple swirl does the trick.
  • Can Repour be recycled?  Yes. Repour is made of 100% recyclable materials. We recommend checking your city's recycling program to understand exact methods of recycling in your area as standards and processes vary by municipality in the US. Check out our Repour Recycles page for information on recycling large quantities or if you're interested in becoming a collection point.
  • What is the shelf life of an unused Repour? A minimum of two years with no loss of function.
  • Does Repour work on sparkling wine? Repour works on sparkling wine as it removes the oxygen with no impact on the CO2, but the pressure inside the bottle can cause it to pop off the top. We know of people who are using it on sparkling wines now, but we don't endorse that use due to the risk of it popping off the bottle. We're working on a fixture that will securely hold Repour on a bottle so it can be used with no concern. Stay tuned!
  • How do I know if my bottle is securely stopped and Repour is working? Repour is designed to fit 99% of bottle neck diameters. To ensure a proper seal, give Repour a push into the bottle.
  • Should I still refrigerate my opened wine in an effort to further reduce deterioration? With Repour, refrigeration is not needed to slow deterioration. If you want to refrigerate your wine, go ahead; it will not interfere with Repour's ability to perfectly preserve your wine.
