"Wagner-Stempel's liquid postcard from Siefersheim is named “Porphyr" after the volcanic soil. The vast majority of their Riesling vines are planted in two historically-celebrated Grand Cru vineyards, namely Heerkretz and Höllberg, and the Porphyr bottling is a declassification from these sites. For Burgundy lovers, this would be the equivalent of a Chambolle-Musigny producer making a village wine from declassified Musigny and Bonnes-Mares — except that you can afford this version, and anybody who finds the comparison to be ridiculous obviously hasn't had much experience with Wagner-Stempel's Rieslings."
