While still only a neophyte, I found that sampling a case of these wines with friends over seven days proved to be an effective method (at least for a consumer) of picking out the best. I think I can now fairly say I know what I am looking for from these wines - a briney nose, a touch fuzzy on the palate, with the texture of ice cold oysters in the mouth and just the faintist hints of rose water, honeydue, and apricot.
All wines were purchased at retail in Manhattan and Brooklyn for under $30, most under $20, my favorites listed below in descending order of deliciousness.
2007 Joh. Jos Christoffel Erben Urziger Wurzgarten Riesling Kabinett (Gutsabfullung) *** Sauvignon color with green tint, mildly fizzy, with brine and honey on the nose. Very light in the mouth, with honeydew and warm lard on the finish. Enjoyed this immensely. For great info on this estate, check out the Wine Doctor.
