I am pretty sure that it is a matter of time before corks are a thing of the past. For all of the reasons listed above regarding the decomposition of the cork, leakage, oxygenation and flavoring of the wine. Another consideration is that the bulk of cork comes from a specific type of Oak grown mainly in Portugal and Spain. With the consumption of wine increasing dramatically, the supply will simply be exhausted.
The screw cap is certainly superior to any other type of closer and it is estimated that approx. 10% of wine spoils due to some complication dealing with the closure (either decomposition, tainting or incomplete closure.)
I do understand the stigma of the twist cap or boxed wine...but I think that will change with time...maybe make the cap look like a cork...who knows. One of the best glasses of wine I have had of late came from a keg...yep, a keg...check it out! http://kdrv.com/news/local/137675
That is the future!
