I suggest exploring Chianti, then Brunello di Montalcino
for another axis of interest, try Barbaresco, then Brunello
Matt Kramer has an xlnt small book on Italian Wines, "Making Sense of Italian Wine"
a good wine shop is worth it and many will restart tastings in store and classes soon; if none near you try Kermit-Lynch in Berkeley, they have a good newsletter (not as good as his dad put out) and will ship to you
BUT, but... wines need a few years to be really at their best (or even drinkable) - Luckily, the Italians will not release a wine right away so that helps
