You might be wondering what the heck is wrong with using a glass bottle for wine anyway? Well, not that much — if your wine is from down the street, ie. very local. Plenty of lucky folks on the West Coast and in France, Spain and Germany can drink wine that’s made fewer than 100 miles away. But if you don’t live in a wine-growing region, as I don’t (if you live on the East Coast, it’s actually more eco-friendly to get European wine that’s shipped on a less-polluting boat than Californian, which is trucked).
Since plenty of wine is transported pretty incredible distances (I HATE that my favorite wine is Shiraz from Australia), the weight of all that glass really adds up to lots more fossil fuel burning than need be if the wine were packaged in a lighter material. While you can’t change much about the weight of the wine itself, smart design can lighten the weight of a case of wine bottles.
