Once Sparkling Wine has been opened, it is important to preserve it properly to enjoy the rest of the bottle later. Le Creuset's Sparkling Wine Crown Stopper is well suited for sparkling wine bottles. It slides on and around the neck of the bottle creating an airtight seal to maintains flavour and fizz, whilst it is strong enough to prevent leaks when bottles are turned on their sides for storage. • Stylish, premium black nickel finish • Easy to use lever action • Airtight seal for maintaining flavour and fizz • Store bottles on side without leaking • 5-year warranty
