This new accessory allows wine lovers to enjoy their wines with screw caps for up to three months after the first pour using their existing Coravin system. Simply remove the screw cap from the bottle and quickly replace it with a Coravin screw cap. Once attached, you can pour as usual with your Coravin system. Coravin screw caps are available in two sizes (Standard and Large) to ensure compatibility with all bottle sizes. They combine self-sealing silicone with a premium disc to create a tight seal that protects the remaining wine in the bottle for up to three months. Each screw cap can be pierced up to 50 times, making each cap reusable for approximately 10 bottles of wine.
