Which soil type is most commonly found in Bairrada?

Sandy soils
Clay-based soils
Volcanic soils
Loamy soils

The correct answer is: Clay-based soils

Bairrada, a notable wine region in Portugal, is indeed characterized primarily by its clay-based soils. These clay soils are well-suited for viticulture, particularly for the region’s prominent grape varieties, such as Baga, which thrives in these conditions. Clay retains moisture effectively, benefiting the grapevines during drier periods. This moisture retention helps support the vines, allowing for a balanced growth cycle and contributing to the rich and robust character often found in Bairrada wines. The clay also provides essential nutrients, fostering the complexity and depth of flavor in the wines produced. While sandy, volcanic, and loamy soils might exist in various regions or contribute to the overall diversity of soils in winemaking, they are not predominant in Bairrada, which is recognized for its distinctive clay-based terroir.
