A group of winegrowers is campaigning against the obligation to place a cap on wine bottles. Often made of a mixture of plastic and aluminum, the cap represents 0.6% of the industry's greenhouse gas emissions.

The "Ca décoiffe en Champagne" collective is calling for the freedom to dress up their champagne bottle or not. The metal headdress was historically "invented" by the Champenois. When opening a bottle, you tear it, and this contributes, in the collective imagination, to the magic of champagne. However, the headdress only has aesthetic value but no longer technical utility. The headdress constitutes for the profession "an identity code inseparable from champagne wines," as confirmed by a group of experts. The Interprofessional Committee of Champagne Wines (CIVC) and the General Union of Winegrowers (SGV) wanted to impose the cap, but even though Europe was lifting the obligation, we decided to step up to the plate.
