Vintage or FAIL?

"Men are like wine - some turn to vinegar, but the best improve with age"

Pope John XXIII

C and I recently moved back into Mum's place to save up for our wedding.  We were clearing out the kitchen cupboards to make room for my copious amounts completely normal sized hoard of baking gear when we stumbled upon a treasure trove of old bottles of wine.

Now, we are talking high quality vino here: a 2000 Bordeaux, a 1999 Chardonnay, a couple of 5-10 year old Australian reds.  My dad was a big red wine enthusiast and between bottles he bought and ones we got as gifts we seem to have amassed a bit of a collection over the years.  There was even the red I bought for him in France when I was on exchange there back in 2000 that he was going to open on my 21st birthday.  When dad passed away, there was no one else in the house to appreciate the alcomohol and so the bottles sat in the back of the pantry, gathering dust, forgotten...until now.

So what to do with this antique wine hoard?  I mean we could try to sell them but they've been sitting in the kitchen cupboard this whole time...not kept in a fandangled temperature and climate controlled cellar of any sort.  Will they still be good? Or will they be vinegar?

C suggested that we should open one bottle at a time, take them to a dinner party or out to a restaurant and basically play wine russian roulette.  It will either be an amazing drop or will it be super bad: Vintage or FAIL?
