the cork thing is an interesting topic.
cork has been used for a long long long time. cork oak is native to the Mediterranean area, so did the Phoenicians use cork? dunno, but sealed amphora from those eras are now and then found in shipwrecks.
there was a time when only the el-cheapo wines came with a screw cap. Thunderbird and the like . . . .
enter the composite plastic cork.
engage the debate: is the composite plastic better or worse than a (good) screw cap or cork?
as a wine guy once said: ask me again in fifty years
unfortunately, all the Phoenician and Roman wine critics are,,, uhm,,,, dead.
the basic question: "only cheap wines use not corks" is flawed
the arguments of "corks breathing", cellar aging, etc. are largely not applicable to white wines - whites are rarely aged to any serious time/decades degree.
which leaves "the reds" - and precious few of those have demonstrated unbelievable quality improvement by long term cellaring.....
just because some unopened bottle of 18-double-squat wine/brandy sold for billions does _not_ automatically imply it is still drinkable . . .
so, we're left hanging on both horns of the dilemma - centuries of experience that says cork works (uhmmm, the Phoenicians probably did not test the composite plastics . . . .) against the modern scientific community who can now prove to parts per trillion that cork-borne mold/fungus/nasties killed the wine
vs.
the "metal doesn't breathe" crowd - who unfortunately have that position harpooned by the fact that although metal is a really good gas barrier, there's a plasticized material as a seal between the glass neck and the metal cap that is _not_ such a good gas barrier.
don't ask me - I've decline all requests for interviews because quite frankly I expect to be in company with the Phoenicians in another fifty years . . .
