Which grape variety is sometimes blended with Tempranillo in Rioja DOCa?

Garnacha, also known as Grenache, is a grape variety that is commonly blended with Tempranillo in the Rioja DOCa (Denominación de Origen Calificada) region of Spain. This blending is significant because Garnacha adds fruity richness and a softer mouthfeel to the wine, which can enhance the overall complexity and balance.

Tempranillo, known for its deep color and flavors of red fruit, leather, and earth, gains additional aromatic layers and a fuller body from the inclusion of Garnacha. The combination of these two varieties is particularly enjoyed in both traditional and modern Rioja wines, contributing to a diverse range of styles.

The other grape varieties listed do not have the same traditional or practical significance in Rioja. Cabernet Sauvignon, while grown in some regions of Spain, is not a key player in the classic Rioja blends. Chenin Blanc is primarily associated with white wines from the Loire Valley in France and South Africa, and Zinfandel is strongly linked to California, making them less relevant in the context of Rioja’s red wine production.
