A fine wine as they age and mature they improve immeasurably.
The best ones are those lovingly stored in a cool dark place for many years.
A really fine one can cost a fortune.
They should be savoured slowly and not a single drop should be wasted.
If you aren't careful with them they can stain your clothes (ooer!)
The cheaper ones can always be put to good use in the kitchen.
They make good presents at xmas!
France, USA, Australia, Italy, and most hispanic countries all make the really good ones. Britain turns out some quirky types with loads of character but no real body or staying power...
