The team spent four years redesigning the sparkling wine bottle to reduce the glass weight while maintaining the same external shape.

Simona Filosi, Martini senior packaging developer said: “We are talking about a bottle for sparkling wine that involves quite a bit of liquid pressure inside.

“Today, when you compare the old and new bottles side by side, you cannot tell any difference in terms of shape. However, by reducing the glass weight, we reduce the energy required to make the bottles.”

The annual energy savings from lighter-weight glass for these Martini bottles is equivalent to 330 fewer cars off the road in a year, the company said.

Since the company began tracking its global impacts on the environment, Bacardi claims to have reduced nonrenewable energy use and greenhouse gas emissions from production by nearly 28%.
