What I Learned
The Kaiserstuhl is a wine district within the German wine region of Baden. Baden has a large number of wine districts, and with almost 4300 hectares (over 10,500 acres), it is the largest of all nine wine districts in Baden.
This district is one of the warmest sites in Germany, with some of the highest average temperatures and the highest average hours of sunshine per year. In this district, the vines are planted mostly in terraces, mostly on south facing slopes of the Kaiserstuhl, maximizing exposure to the sun in this already sun-drenched (relatively speaking) district. Another interesting aspect of this district is its base. It is volcanic, as this whole area was once one giant volcano. A layer of loess lies on top of the remnants of the old volcanic lava, which seems to retain heat to an amazing degree. The cuts in the terraces reveal incredible depths of the light-colored loess layer.
