Well, everything stored in plastic bottles and containers tastes a little plastic-y to me. But alcohol will dissolve all kinds of things that water can’t, so I’m pretty sure this is much worse.
The thing to consider is: what quality of distillation comes with a package that’s just a little nicer than a plastic bag?
For us Americans, I feel like that’s a small blessing. An up-to-date graph would be less moldy, but still painful to consume.
