Cavallotto and Castiglione Falletto
As we move west across the broader appellation of Barolo, there are 3 communes that become critical to experience and understand., and all of them are impacted by the transition from Helvetian soils to Tortonian.  In contrast to Helvetian soils, the Tortonian soil influence brings forward wines that are more perfumed, elegant, and approachable; the color leaning towards a ruby hue. The wines of this soil also arguably mature more quickly, but still have the same great staying power of the entire Barolo appellation.The Tortonian soil on this side of the overall appellation is characterized by the following properties:

• Blue tinted (darker in color)
• Compact calcerous marl soil mixed with sand
• Fresher, more fertile
• Rich in magnesium, manganese

Most strikingly impacted by these soils changes is Castiglione Falletto, a cru that is special in the sense that it balances Helvetian soil with influences of the more Western Tortonian soil that extends across the Central Valley of Barolo.
