We are back to talking about screwcap versus cork with wine closures. After I attended the Unified Grape and Wine Symposium I was pretty sure that the debate was over, screwcap was the future of the marketplace. But Decanter has some news that could change everything. According to recent tests conducted by Cairn Environment for Oeneo Bouchage in France, screwcaps produce the biggest carbon footprint. The production of screwcaps gives off far more CO2 than the production of both corks and synthetic closures.
Will this make a difference in how screwcaps are perceived by the world? With the increasing push toward green products this news could have an impact. Another thing that the article doesn't mention but that might also be a consideration is the recycling of wine closures. In that case I would suspect that cork might also come out ahead.
