Can screw top wine be corked?

Yes, it can if the screw top has been left off for a length of time and airborn spores of fungi have entered the bottle.

Also screw caps can cause sulphidisation which is another type of taint.

Sadly the life of a bottle of wine in my cellar is short lived.

Your question is ambiguous.

If you mean - can you put a cork in the top after you've partly consumed the wine - then yes, but it won't be any more effective than replacing the screw stopper.

If you mean - can the wine be corked in the sense that it has become vinegary and gone off - the answer is no, since there has been no cork for it to react with.

Yes. Corkage comes from TCA contamination, which can be found where wines are aged, bottled and/or stored. It has nothing to do with the actual cork.

YES

Corking is normally the result of infection in the natural cork .. HOWEVER .. It can also come from infection at the winery itself.

I'm sure it can be, you just need to find the right size cork

Yes you could but it wouldn't make any difference to the wine, would make it look nicer thou if your serving it to people thou or you could just use a nice bottle top.

use a spoon

you can use a stopper

no use your teeth
