Grape Spotlight: Mosel's Bernkasteler Doktor & Weingut Wwe. Dr. H. Thanisch Riesling

Viticulture started in the Mosel in the 2nd century when Romans planted vines on the steep slopes bordering the Mosel River. These slopes can reach 68-75 degrees and adds to the picturous charm of this wine region.  As the river meanders from its confluence with the Rhine River to Germany's border with Luxembourg and France, it passes through famous wine villages along the valley such as Brauneberg, Erden, Graach, Piesport, and Bernkastel. 
Bernkastel is located right on the banks of the Mosel river, between Graach (to the north) and Piesport (to the west). This is the very heart of the Mittelmosel ("middle Mosel") and is arguably Germany's top wine-growing location. The Mosel river forms a hairpin bend here, inside which lies a finger of land dominated by steep, towering, vineyard-lined slopes. -- wine-searcher.com. 
This sub-region shares many characteristics of the larger Mosel region, a long growing season featuring a cool, northern continental climate. Yet there are several factors that facilitate the ripening of grapes. The vineyard slopes optimize the vines' exposure to the sun while simultaneously solar radiation is reflected off the rivers' surface. And the dark slate soil absorbs heat during the day and radiates it back to the vines at night.  The disadvantages of such steep vineyard sites and porous soil are that it requires hand harvesting and in winter, after heavy rain, workers must carry back soil that has run off the vineyards.  One of Bernkastel's most famous vineyards is Bernkasteler Doktor -- a small (3.25 acre / 1.8ha) plot that directly borders the village of Bernkastel. The Riesling vines are planted on a south-southwest exposure and a steepness between 60 and 70 percent -- providing ideal conditions for all-day sunshine. The vines are also predominantly ungrafted as the gray slate provides protection against phylloxera and average 60 years of age with some over 100 years old.  Parcels of the Bernkasteler Doktor vineyard have belonged to members of the Thanisch family for more than 200 years and the family has a documented winegrower pedigree since 1654. Today Weingut Wwe. Dr. H. Thanisch is now up to its twelfth generation and is also proud of their female tradition. The name “Wwe. (widow) refers to Katharina Thanisch who was only 30 years old when her husband, Dr. Hugo Thanisch, died. In 1996 Sofia Thanisch became the fourth successive female family to operate the winery and will be succeeded by her daughters, Juliane and Christina. 

The grapes from the Bernkasteler Doktor vineyard are handpicked, slightly squeezed, and then left for 14 hours to macerate before being gently pressed. The wine is then naturally fermented without any addition of cultured yeast or enzymes for a period of four to five months. After fermentation, the wine matures for several more months on the lees in order to gain more stability and complexity. A recent Hopwine salon provided me an opportunity to sample two of their Bernkasteler Doktor wines along with another Bernkastel Riesling.
