To preserve its delicate flavor and effervescence, sparkling wine should always be served well-chilled. Place it in the refrigerator for at least 3-4 hours before serving. Then, set your bottle in an ice bucket filled with water and ice, which will keep it at the right temperature as you drink it. Ice buckets will also add an elegant touch, but commercial refrigeration may be most practical for large receptions.
Since Sparkling wine is bottled under pressure, be sure to open it carefully and closely follow the instructions on the bottle. A standard 750 ml bottle will yield approximately six champagne flutes, and it is best to estimate at least two flutes per guest.
Wine experts recommend serving sparkling wine in a tulip-shaped glass, so shaped to retain and enhance the effervescent character of sparkling wines. The champagne flute remains a popular choice, but both will add an elegant touch to your cocktail party.
