Champagne have been made for special occasions and people, the most notable example perhaps being the 20 fluid ounce / 60 cL. bottle (Imperial pint) made especially for Sir Winston Churchill by Pol Roger. In 2009, a bottle of 1825 Champagne was opened at a ceremony attended by 12 of the world's top wine tasters. This bottle was officially recognised by "Guinness World Records" as the oldest bottle of Champagne in the world. The contents were found to be drinkable, with notes of truffles and caramel in the taste. There are now only two other bottles from the 1825 vintage extant.
Wine bottle surplus of green glass because it imports a large quantity of wine but produces very little. 1.4 million tons are sent to landfill annually. Glass is a relatively heavy packing material and wine bottles use quite thick glass, so the tare weight of a full wine bottle is a relatively high proportion of its gross weight. The average weight of an empty 750 ml wine bottle is 500 g (and can range from 300 to 900 g), which makes the glass 40% of the total weight of the full bottle. This has led to suggestions that wine should be exported
