The previous Grape Spotlight focused on Mosel's Bernkastel district and specifically the Bernkasteler Doktor vineyard. In this post, the focus remains on Bernkastel but specifically on Riesling grown in the Leiwen sub-region. The town of Leiwen is located on the western side of a hairpin in the Mosel river near Trittenheim and far upstream from Bernkastel. As opposed to the south-southwest exposure of the Bernkasteler Doktor, Leiwen vineyards follow the river and can face east, north, or as in the case of the Leiwener Laurentiuslay vineyard, west-southwest. Vineyards facing east are planted on more gradual slopes, whereas vineyards on the northeast-oriented banks and west-southwest are planted on steep slopes. 
Leiwener Laurentiuslay is the farthest upstream of all the Bereich Bernkastel sites rated as Grosse Lage by the VDP (Verband Deutscher Prädikatsweingüter). "The gray slate soil provides excellent natural water management, balancing good drainage with sufficient water retention for warmer summers. Lizards can be found sunning themselves on the slate in the near-Mediterranean mesoclimate". -- wine-searcher.comWeingut Nikolaus Köwerich is a German producer utilizing Riesling grown in Leiwener Laurentiuslay and on the similar sunbaked blue devon slate soils of the Köwerich Allemagne vineyard. Church records show that Nick Köwerich's family has been living in Leiwen since 1548, potentially part of the Riesling Mosel wine tradition that began in 1465. Both he and his wife Annette are agricultural engineers and apply modern techniques to the traditions Nick learned from his father's vineyard.

If you seek a dry, minerally driven Riesling, then look no further. Expect bright lemons, racy minerals, a hint of tannins, and a long dry finish.

On the other hand, if you prefer a sweeter, more full-bodied Riesling with similar salinity then Miss Mosel is your wine. There are a plethora of fruit flavors from citrus to stone fruits to green apples -- all combined in a creamy body -- and balanced with sufficient acidity.
