Southern French wine producer Skalli is introducing lighter bottles as part of its eco-friendly strategy.

The switch to lighter glass across its portfolio, which includes single estate and premium brands such as Domaine du Silène and Terra Vecchia, would cut its carbon footprint 15% to 20% per year, it said.

"We already recycle as much as we can in terms of glass, cartons and plastics during production and all water used in the winery is collected rather than flushed away for re-use in irrigation," said president Robert Skalli.
