I opened this to show a friend how well that Rieslings can age.  A mostly dry Riesling from 1996 and it was beautiful.  Golden in color, slightly deep.  The nose is clean with just a bare whiff of petrol.  There was grapefruit peel, slight lemon notes and "wet rocks".  On the palate, it was rich and tasted dry but perhaps a bit of residual sugar left.  Nice round texture but enough acidity to easily cut through it.  Long finish.  It begs for food and rewards the food nicely.
