Designed exclusively to be used with the Coravin Wine Preservation Opener. The perfect accessory to enhance the taste of your wine in seconds by mixing the right amount of air with the wine as you pour. Its unique design uses the system’s pressure to force wine through 24 carefully placed and sized holes. By creating small jets that dramatically expand the surface area of wine exposed to air, it rapidly aerates the wine to yield silky, smooth, and aromatic results equivalent to decanting wine for approximately 60 to 90 minutes.
