Tecnically spoken it would be a improvmeent indeed. Corky whiskies are our enemy!
Esthetically spoken plastic would not be a improvement. Since somehow we all want Whisky to be pure and natural as possible. And how weird it may sound, a plastic cork doesnt fill that profile.
I'm sure distilleries are aware of that, and for that reason not using plastic corks yet. I have a feeling plastic corks would even be cheaper to produce then natural cork. anyone has more information on this?
In the end I'm pretty sure we will see a increase in plastic corks until we are all used to it
