My co-rambler is away, ostensibly vacationing in an undisclosed location in Cornwall, but I can reveal that he is really working on a piece of investigative journalism to reveal the craziness of some German wine makers. Like you, I don't have the faintest idea what may be coming. Anything from mild eccentricities to all-out insanity could be on the ticket.
Here's one thing I know about German wine makers, though (segue alert!): They can make quality dry Riesling at crazy prices. Case in point: Karlheinz Schneider, an all but unknown producer from the Nahe, itself an all but unknown region (excepting Dönnhoff!) in the rest of the world.
