I had a bottle of Friedrich Wilhelm Gymnasium 2007 Graacher Himmerlreich Riesling Kabinett. Good minerality with the right amount of sugar (not much). Elegant, as I expect from German kabinetts.
I got turned on to good Rieslings while working in a wine store in Indy called Kahn's Fine Wines. (I often had to teach customers that not all Rieslings are mouth-coating sugar bombs.)
Had the opportunity to try many fantastic Rieslings, as well as hundreds of other wines of all qualities. The oldest was a 1969 Burgundy-- which was past its prime; we could count on the owner never to open the truly good stuff. The oldest, most expensive bottle in the store was a 1869 Mouton Rothschild with an asking price of $10,000.
