I've had a lot of good feedback for my Bordeaux quiz and I've rolled out a few more (and plan to continually add more). Here's the link to the main page where you can get to all the region quizzes. The map on the page will update automatically as I add more regions.
For anyone just starting out with their wine education, I've added an "Easy" French quiz that has only the main regional appellations. Italy should follow soon.
