Spoilt Wine

I had the chance of tasting a spoilt wine. When I say spoilt, I mean a wine bottle which was opened years ago, but is still standing on a shelf. I swallowed the tiny sip of that wine so quickly, I hardly remember how it tasted. All I can say is, it is impossible that you don't notice that it is spoilt when you taste something like that :) If you ask me why I tasted it although I was sure that it was spoilt, my answer would be "curiousity". This is how everything started anyway, out of curiosity...
