Ideally, Champagne should be stored at a constant temperature (13-15°C) and away from light. Champagne is shipped at full maturity, so it is ready for drinking shortly after purchase. However, it may be kept longer if it is stored under ideal conditions.
Non-vintage Champagne should be served between 7 to 8°C, vintage and older Champagnes should be served between 8 to 9°C.
The best glass to serve Champagne is the tulip-shaped glass. Tall, wide and large, it allows the bubbles to express themselves fully, and the aromas to develop better than in the flute or the traditional saucer-shaped glass.
