Over the past couple of years, the wine industry has gone from mostly glass bottles with corks to a bevy of boxed varietals and wines with screwcaps. Now meet the industry's newest container contender: plastic wine bottles. Because they're one-eighth the weight of a typical glass bottle and take up 20 percent less space, plastic bottles are more cost effective and environmentally friendly. They also enable winemakers to save fuel by shipping more wine per truck. The downside? Plastic simply doesn't provide the same seal as glass, and the bottles come with "drink by" dates — so they'll only be used to package wines that are meant to be enjoyed right away. I can't help but wonder whether the plastic containers could pose a health hazard. How do you feel about the matter?
