Great question! Since Argon is a gas, your can of VineyardFresh will feel super light and "empty" from the first day you receive it. But - don't worry. If you go to spray VineyardFresh wine preserver into your open bottle of red wine, and you hear the "phfft phfft" - you're good! The argon is being sprayed from the canister into the bottle of wine, and will create the protective layer that stops the wine from oxidizing and going bad.
What if It's Really Empty?
BUT...if you go to spray VineyardFresh into your wine and don't hear anything.....don't panic!
It's just time to buy a new can of VineyardFresh. Like right now. And in the meantime, you may just have to finish off that open bottle in the next few hours. (Our delivery isn't that fast.)
