70:70 vision from Jean-Charles Boisset

I spent a fascinating few hours chatting to Jean-Charles Boisset, yesterday for an interview to appear in Meininger's Wine Business International. Among the many subjects on which the man the man behind some 35 wine brands such as Bouchard Ainé, Boisset, Domaine de Vougeraie ad De Loach in California was eloquent was his take on wine packaging. He calls this his 70% rule, and I thought it reprinting it here:

THE BOISSET 70% RULE
More than 31.2 billion bottles of wine are consumed on earth each year. 70% of that wine retails for less than $10 per bottle. Within that 70%, at least 70% is consumed between 28 minutes and 3 hours of purchase. 70% of the cost of that wine is the packaging (bottles, corks, capsules, and all other dry goods), shipping, and other related supply chain costs. The vast majority of the environmental impact of wine comes from the production and disposal of the packaging and from shipping the heavy merchandise around the world. We know that wine meant to be enjoyed young can be kept fresh and flavorful in a variety of packaging formats. Why then not offer this wine in lighter, more environmentally-friendly packaging that will reduce its carbon footprint and cost less to ship, yet still provide the high quality that customers demand? By lightening the packaging and reducing its carbon footprint, the wine world can make a dramatic difference in the health of our environment…and invest in better quality wines!”

To which I would add a question of my own. Could someone please tell me why rosé, any rosé, is ever put into a glass bottle with a cork?
