(Washingtonpost) - It’s the fifth day of our trip through the German vineyards of the Mosel Valley, and we’ve had a lot of wine. But not as much as Georg.Georg has spent the evening as he spends most evenings: stopping by each table, welcoming people to his winery. And, being a hospitable sort, he has had a glass of wine at each stop. Germany’s Mosel Valley: Where to go and what to know Georg’s wife, on the other hand, is quite sober. A 40-something woman with sensibly cut brown hair, Hildegard is low-key but affable.
