The UK's Wine Society, a member-owned community of oenophiles, has contracted some unusual packaging for some of their wines: Flat-shaped plastic bottles, made from recycled ocean plastic, and recyclable themselves. After conducting a study, the group has concluded that using this recycled PET, and in this shape, is more sustainable
We said the same thing about corks.
NZ (and Australia?) doesn’t really do corks any more. For sparkling wines, yes. But I’ve not touched my bottle opener in years.
We also sell (some?) wines in PET bottles, but they’re usually single serve/hotel-minibar bottles so not mainstream.
If there’s a cost incentive to the winery, and no impact of quality to their product, I think they’ll slowly push for a change.
But first, they’ve got to ascertain it won’t affect the product.
