Apparently not. The big cork producers like Amorin has done extensive research to remove the much dreaded cork taint, and reports are they have succeeded in doing so.
There is of course a place for the screw caps in fresh, young wines – to be drunk soon, but cork is still tops as gurus from Portugal will attest, and there are very few wines in screw caps to be found in Portugal.
You will not find any French 1st growth in screw caps either, or any port from the Douro, nor Meerlust or the upper echelon Nederburgs, from the Cape wine-lands.
Cork is much, much more eco- friendly, keeping people working in the country and at the same time protecting the european lynx and many birds that live in cork forests.
