J.J. Christoffel Erben, in Mosel, has been in the Christoffel family for more than 400 years. In 2001 Hans-Leo Christoffel leased his vineyards to Robert Eymael, who had been a consultant to the estate for nearly a decade. Today the Christoffel family and Eymael collaborate to ensure that the wines continue to have what Robert M. Parker Jr. calls “the uncanny marriage of opulence and polish with transparency of flavor and overall level of excellence that has always characterized Christoffel’s estate.” The estate’s numerous Rieslings range from sweet to dry.
