small slice of perfection, the four-acre Erdener Prälat (AIR-din-er PRAY-laht) produces some of the greatest wines in the Mosel valley. It has 100 percent south-facing red slate soil and an extraordinarily warm microclimate, yielding wines of unequaled power and nobility. The vineyard’s exposure, combined with the warming effect of the river and the massive, heat-retaining cliffs that surround it, ensures exceptional ripeness in every vintage.
