Apart from the Côte d’Or in Burgundy, perhaps no other wine territory has been dissected in greater detail than the Barolo zone. This makes perfect sense, as these are arguably the two most ideal representations of the concept of terroir; just as Pinot Noir from one village in Burgundy reveals different flavors than that of another nearby hamlet, so too offerings of Barolo from various communes often display diverse characteristics, despite the fact that every wine here is made exclusively from Nebbiolo.
There are 11 approved communes in the Barolo production zone. For this article, we will deal primarily with the five largest: La Morra, Serralunga d’Alba, Monforte d’Alba, Castiglione Falletto and Barolo itself. The remaining six are Cherasco, Diano d’Alba (interestingly, planted more to Dolcetto than Nebbiolo), Grinzane Cavour, Roddi, Verduno and Novello; these last two are home to two of the most in-demand vineyards in the entire zone: Monvigliero in Verduno and Ravera in Novello.
