The use of a 400 g-Bordeaux bottle vs. a 600 g-bottle leads to considerable environmental benefits. Glassmakers estimate an energy consumption per kg of produced glass between 12 and 15 MJ (Mega Joule), mainly depending on the percentage of recycled glass. Adding energy costs for transportation and disposal, we can consider an average total energy consumption of 15 MJ per kg of produced glass, equivalent to the emission of approximately 2.7 kg of CO2.

With a lighter bottle, the energy saving is more than substantial:
The choice of cork stoppers is also a functional and sustainable choice. The natural cork stopper is renewable, recyclable and 100% biodegradable.
