The height of the glass also helps to maintain the sparkling effect for as long as possible, just as the small opening at the top of the glass helps to retain the bubbles. This allows both the taste and the sparkling visual effect to be enjoyed for longer. At the same time, the long stem lets you hold the champagne glass without your fingers transferring heat to the drink. This ensures your sparkling wine remains at just the right, cool temperature. The glasses hold 20 cl and are dishwasher-safe. Pack of 6 pieces.
