Black Plastic Top Tasting Cork. Bag of 12
Black plastic top tasting corks are used in place of the regular cork once the bottle has been opened to help preserve the wine for a few days. Once a wine has been opened oxygen will quickly start to oxidize the wine, and a tasting cork will not stop this process, but it will help slow it down. This gives you more time to finish the bottle of wine. 12 tasting corks per bag.
