Which region has more varied soils: northern or southern Rhone?

The southern Rhone region is characterized by a significant variety of soil types, which contribute to the diversity of styles and flavors found in its wines. In the southern Rhone, the soil composition ranges from clay and limestone to sandy soils, with variations influenced by the presence of river deposits and the topography of the region. This diversity allows for a wide range of grape varieties, including Grenache, Syrah, and Mourvèdre, each of which thrives in different soil conditions, thus enhancing the complexity of the wines produced.

In contrast, the northern Rhone generally has more homogenous soil types. It is primarily characterized by steep, terraced vineyards along the Rhône River, with predominantly schist and granite soils that are well-suited for varietals like Syrah. While there is some variation, it is not as pronounced as in the southern Rhone. Thus, the southern Rhone's varied soils play a crucial role in shaping its distinctive wine profiles, making it the correct answer.
