Sparkling wines and Champagne should always be stored in a cool and dry place away from light and heat sources. The ideal temperature for storage is 13-15 degrees C.
Warning: Sparkling wines contain high natural pressure. Do not allow bottles to get warm. Chill bottle before opening and avoid shaking. Point bottle away from others and yourself when removing wire, hood and cork. Hold the cork firmly and twist out slowly by hand. Never in any circumstances use a corkscrew to open.
