Which grape variety is often blended with Grenache in southern Rhône wines?

Mourvèdre is often blended with Grenache in southern Rhône wines, and this combination is particularly noted in the production of red blends. Grenache brings bright fruit flavors, such as strawberries and raspberries, along with a soft tannin structure. In contrast, Mourvèdre adds depth to the blend through its characteristic darker fruit flavors, such as blackberries, as well as various herbal and gamey notes. The addition of Mourvèdre also contributes acidity and tannin, which can help balance the sweetness and body of Grenache, resulting in a more complex and structured wine.

This blending practice is integral to the style of many famous southern Rhône wines, including Châteauneuf-du-Pape and Côtes du Rhône. The synergy between the two varieties enhances the overall profile of the wine, making it more age-worthy and enjoyable.

The other varieties mentioned, such as Chardonnay and Sauvignon Blanc, do not typically appear in Rhône red blends, as they are primarily white grape varieties, while Zinfandel is more associated with Californian blends rather than the Rhône Valley. Thus, Mourvèdre's compatibility with Grenache in these blends is well established and widely recognized in the context of southern Rhône winemaking.
