Ohio River Valley Viticultural Area ... We're Number 1

Here's something I didn't know until today:

The Ohio River Valley is the largest officially recognized viticultural (wine-producing) area in the United States.

However, some folks in the Upper Mississippi River Valley plan to form a larger area.

I'm not much of a wine fan (although in high school my buddies and I did try to distill moonshine and vodka with chemistry lab equipment, with little success), but I did find that interesting.
