One of the most talented Winemakers in Alsace ... he has Riesling and Gewürztraminer growing in prime sites and it is what he manages to do with these that ranks his wines among the very best in Alsace. Although his generic Riesling has great class and finesse, his Grand Cru Geisberg and Grand Cru Osterberg are very much finer. The Geisberg is the riper and more opulent, with a wisp of smokiness to the fruit, the Osterberg is more classic and flinty, requiring longer in bottle.
