Is there anything wrong?

I have been wondering this for a while but never got round to blogging about it. It has been prompted by my wife's great love of white wine and the number of bottles we have been consuming of late. It has caused me to ponder - is there any difference between a cork and a screwtop?

There was a time when the screwtop was the sign of a truly awful vino - maybe a Liebfraumilch or a dodgy Valpolicella. But now nearly everything comes with the easy access option. I am no wine expert but I am intrigued as to whether using a cork makes any difference to the quality. Or is it just pure snobbery?

I wonder if it could be extended to grappa too. Although I like the reassuring "pop" of a cork stopper. There is something almost scientific about opening a bottle. You feel like you should pour it into a test tube and watch the fumes fly...
