CorkPops Wine Preserver duplicates winery systems designed to prevent free-radical oxidation.
Simple and easy: Insert the patented injection tip into the mouth of the container. Three quick press downs allow the inverted can and injection tip to force the existing air out and allow the inert gas formula to gently flow in. To preserve wine safely for an indefinite period, remove the wine preserver and immediately replace with an airtight non-porous stopper. Do not slant bottles or allow them to rest on their sides. Three press downs before storing wine prevent oxidation from occurring, keeping flavor, taste, and bouquet intact. You do not have to worry anymore about finishing the whole bottle right away.
