Tesco, the big English supermarket chain, has launched what is said to be the world’s lightest glass wine bottle, weighing only 300 grams. A normal bottle weighs in at around 450 g. A champagne bottle is around 850 g and some show-off cuvée of body building wines (assuming body building drinkers) have bottles that weigh more than 1 kg!
