The cork forest sucks up CO2 which is generated in part by the plastic and aluminum refining processes. "Endocrine disrupter" is not a phrase you'll see in relationship to cork. And there’s no such thing as a “cork spill.”
In addition, the wine itself has direct contact with the plastic bag, which is a permeable, petrochemical-based material. If the wine has any decent acid in it, that immediately should be cause for concern.
Yes, I know that this topic has been covered ad nauseum by every wine blog, website, magazine, book, opinion, study, expert, editorial, blah blah blah. I saw the dead horse. I decided to beat it.
