This system combines wine preservation with aeration, delivering a more flavorful wine as you pour with the included aerator attachment.What it does: The ingenious combination of the Pivot Stopper and Device preserves the remaining bottle for up to four weeks, ensuring the last glass is just as amazing as the first.Additional features: Unlike other wine preservers, which only delay the oxidation of your wine, this wine preservation system is designed to pour wine without removing the cork, so wine always tastes like it has just been opened-even years later. The noncoring Coravin needle gently passes through corks without displacing cork material. Once the needle is removed, the cork simply expands back to its normal shape. As wine is extracted through the needle, it is replaced with pure argon gas, ensuring oxygen never touches the remaining wine, keeping it as fresh as the day it was bottled.Includes: 1 Pivot Wine Preservation System, 1 Pivot Aerator, 2 Pure™ Capsule and 2 Pivot stoppers.Sizing information: 0.3 lb.; 3.25" x 1.25" x 8".
