Any wine drinker trying to master the wines of Italy has a daunting task ahead. The Italian boot is chockablock with grape varieties both little-known and more common, planted in vineyard sites that vary greatly from region to region, and bottled as both stand-alone varietals and blends. All told, it makes for an impressively wide array of offerings. Luckily for the wine lover willing to undertake this exploration, many of Italy's regions offer good value, delivering wines rated 85 points or higher at very reasonable prices. For $25 or less per bottle, you can stock your cellar with whites, reds and even sparklers that showcase their region's specialties while highlighting the country's overall diversity.
