Last month (maybe two months ago?!), the Nat Decants newsletter headlined with an article about plastic wine bottles. I can't find the text article online, but here's a link to Nat's podcast page - it's on there.
When I think plastic bottle drinking, the only thing that pops into my mind are the plastic bottles of Miller Lite you buy at concerts or football games. You know, the things that can't do too much damage when a drunken jackass heaves one at your head. Practical, sure. Refined, however, they are not.
Now, Nat does point out that these plastic wine bottles, which are made of polyethylene terephthalate (PET) are pretty ideal for poolside or camping, but she also mentions that because they're lighter than glass, they don't require as much energy to transport, and the PET itself is a highly recyclable type of plastic.
Of course, the real test is in the taste. Only a handful of wineries have adopted this format, but having sampled some them, Nat reports that the plastic is odorless and tasteless (well, that's good news). She hedges, though, pointing out that we won't really know if the plastic affects the wine for several years...because who knows what it means for aging.
But interesting, nonetheless. And handy, for the next time I want to throw a wine bottle at Cooper without actually doing any damage. (Kidding. I'm kidding.)
