All Coravin Systems deliver the opportunity for you to enjoy your wine the way you want to versus having to commit to the bottle. The key differences between the Pivot System and other Coravin Systems are how each works and the length of preservation each provides. With the Pivot System, you open the bottle and replace the original closure with the specially designed Pivot Stopper. The Pivot Device is then inserted through the Stopper to pour. The Pivot System works with any bottle of still wine regardless of closure type. Because the bottle has been opened, wine will remain fresh up to 4 weeks. For most everyday wines, this is plenty of time to finish the bottle, knowing your last glass will taste as fresh as the first. The Pivot System provides best-in-class preservation for under $100. All other Coravin Systems feature a Needle that is inserted through the natural cork, extracting the wine without opening the bottle. Because the bottle remains sealed, the remaining wine is preserved for years, continuing to age in bottle as the winemaker intended. For screw cap wines, these Systems can be used with the Coravin Screw Cap accessory and preserved for three months. These models are perfect for pouring special bottles, tasting bottles as they mature, or expanding your at-home wine-by-the-glass menu without worrying about when you will finish the bottle.
