What I Learned:
The Franconian Wine Region in Germany has three distinct wine districts: the famous Maindreieck passing Wuerzburg, the Mainviereck, and the Steigerwald. Unlike the first two, the Steigerwald wine district is not located along the Main River. This means that the climate-moderating effects of a river do not apply here. And since here is in south-central Germany, winter weather can last for longer, with spring weather arriving later, and fall weather arriving earlier, than elsewhere in this region.
