Corked wine from a screw top??
Discussion
I have just sampled a favoured wine of mine that I bought from Sainsburys. Its a Chilean Sauvingon Blanc that has been a screwed top for about 2 years. Being no expert, but understanding wine is corked through air intake, I'm sure this bottle is not right. My question is, can a screw top wine be corked?
Cheers!

I think the bit I highlighted in bold is your problem - but I'm no expert!Cheers!
I don't tend to keep supermarket wine longer than 2 days let alone 2 years
mybrainhurts - thank you. I knew I'd get at least one! Otherwise, this wine is not 2 years old...! I've been drinking the same brand for that period and can pretty much recognise it blindfolded. I'm sure its not the usual taste, and yes perhaps a little oxidation then, as I can taste a sherry like flavour.

A wine is corked when it has been in contact with a cork infected with a fungus that produces 1,2,4-trichloroanisole, otherwise known as TCA. It is this chemical, rather than the fungus itself, that imparts the unpalatable flavours to the wine.
Nowt to do with screw caps.
What he said. Probably.Nowt to do with screw caps.

It's more likely the fact that you should never...ever...drink screw top wine sober.Have a bit more, mix it with vimto and all will be well.
On a slightly more serios note, it's more likely that the flavour has been affected by poor storage, it won't hurt though...save it for later.

I've had real problems with Sainsbury's wine...about 1 in every 2 bottles i bought from them last year was 'off'...whether it'd been sitting for 6 months or 6 weeks on my rack.
They refunded each one, but that's not really the point when you've 10 people round for the wife's birthday and you're opening bottle #4 before anyone's drunk anything!
My guess was it's a problem with how they store the wine...because the bottles I bought from Threshers and Tesco were all absolutely fine.

Very true - the two bottles of Tesco Chablis I intended for lunch on Christmas Day were definitely below par. Unfortunately, with nothing else suitable in the house (I won't make that mistake again!) we had to resort to whatever our local Londis had in stock.They refunded each one, but that's not really the point when you've 10 people round for the wife's birthday and you're opening bottle #4 before anyone's drunk anything!

There is something that screwcaps do that is the equivalent of "corking". Either oxidation or reduction - not sure which but it does happen to a small percentage of wines.
Reduction can occur when wine is bottled under screwcap. This is due to the zero oxygen transfer rate. There is a new screwcap that comes complete with organic polymer membrane which allows an absolutely predicatable OTR to allow the wine to mature perfectly, with a type for white and red wine. I have some samples sitting on my desk ...
TCA, as mentioned above, can occur on poor quality corks, but a reputable producer of fine quality corks should be able elminate this as much as possible through various techniques. Even the best grade corks, and complete corks note(i.e. one single piece, not the often found in sub £10 bracket of 2 piece or aglomerated corks), still have a wider standard deviation of OTR, so results are still not absolutely predictable.
That said, for expensive wine, cork all the way, that is despite me knowing the drawbacks of cork!
Yep! I know, Holy Thread Resurrection Batman!
Did a search and this came up. I have bought 3 bottles of Tescos Vintage Claret Bordeaux as it was recommended on various wine sites and only £5.99 a bottle. First two were fine and gluggable but the third, that I opened last night, is undrinkable. Tastes like vinegar and strips the roof of my mouth.
As the thread discusses, I thought this was pretty much impossible with screw top wine bottles. As I have only poured out a glass I will be taking it back but as it's a pretty Chavvy branch of Tesco Metro, I'll wager it will be the first bottle of wine ever to be brought back for a refund in it's history

A screw cap should provide an excellent seal but it can always be faulty e.g. because of damage from denting or falling on the cap itself.
A screw cap can never be foolproof.
Of course it's also conceivable that a wine produced in large quantities and bottled in batches actually has a problem with an entire batch i.e. nothing to do with the closure
