Although there is evidence of winemaking in Sicily as early as 4000 BC, it would take four millennia before the organization of mighty Rome established Italy and Europe as a wine-drinking empire. Two thousand years later, Italy remains the imperial power in wine: It is one of the most prolific producers, with over 1.27 billion gallons annually. Each of Italy's twenty regions creates wines with nearly every grape, including obscure indigenous varietals and modern international ones, grown between the Alps in the north to Sicily (less than 100 miles across the sea from the tip of Tunisia). The variety of Italian wine is genuinely unrivaled, as one can drink a different grape every single day of the year. Naturally, Italy is celebrated for Sangiovese, Nebbiolo, Pinot Grigio, Prosecco, and Montepulciano. Still, there is much more to explore, from the most expensive Brunello and Barola to soulful Nero D'Avola and Primitivo for under $20. When in doubt, buy Italian. The value and quality are always there.
