Shoot, I had more homework in a wine & viticulture class I took earlier this year. Of course, the one night a week we were in class, we were sampling 4-6 wines. One test was a killer, matching the varietals with their regions in France, Napa, and Italy. Only reason I got an A was for the extra credit for my presentation on German wine.
I could have done that in my sleep as the grizzled veteran of dozens of wine fests along the Mosel River.
