I live in the Mosel Valley so I'm killed for choice. My tip for anybody wishing to gather a lot of good experience in a short while would be to visit the Vinothek in Bernkastel-Kues. They normally have about 60 wines open from some of the better known producers and you can rent a glass for about 10 Euros and get spitting. This is seriously good experience as you'd have to drive for a week to visit all of these guys and risk your license into the bargain - unless you can afford a chauffeur ! Other dates and venues:
03.06.08 The Bernkasteler Ring's Riesling presentation at Kloster Machern. Entry Euro 30,- About 200 wines from about 40 of the Ring's producers, presented personally. It's a great day, my maximum was 87 wines and still standing though I did swallow some of my favourites
Jan 2009 (exact date not yet set) Weinforum, Trier: about 100 Gold Medal winners reassessed to find the best of the best. Try them all, another great day.
Anybody wanting any info, just ask.

And finally, the little known fact, "Feel Good" wine - the DRK (German Red Cross) has it's own vineyards in Bernkastel-Kues, the DRK-Cusanus-Hofgut, which it operates through its Workshop for the Disabled. Please be assured, this is not the sympathy vote. I don't give that kind of recommendation ! These are first class wines, sold at moderate prices and the proceeds go to help fund the workshops.
OK 'nuff said.
