Spirits company Edrington has developed a new bottle prototype for Famous Grouse scotch whisky.
The packaging weighs 340g, a 14% weight reduction.
Edrington director of technical services Mike Rose said "We set out to prove that it was possible to produce a glass bottle under 400g which still supports premium features like engraving and embossing, and can cope with the speed of the production line, which runs at up to 600 bottles per minute."
If adopted, the innovation would allow over 2,160t of glass to be saved every year. If it is rolled out across the industry, it would save over 58,000t of glass annually.
The prototype is expected to be tested in a selection of Scottish supermarkets later this year.
