Which three red grapes are commonly blended in the Rhone region?

The three red grapes commonly blended in the Rhône region are Grenache, Syrah, and Mourvèdre. This blend is often referred to as GSM and is a hallmark of the region's wine production.

Grenache is a predominant grape known for its fruity flavors and soft tannins, bringing a roundness and sweetness to the blend. Syrah contributes depth and complexity, with its dark fruit flavors and spicy notes. Mourvèdre adds structure, tannin, and earthy characteristics, enhancing the overall balance and aging potential of the wine.

This combination is particularly famous in various appellations within the Rhône Valley, such as Châteauneuf-du-Pape and Côtes du Rhône, where winemakers leverage the strengths of each grape to create rich, flavorful, and well-rounded wines that can vary significantly based on the specific blend ratios and terroir.

In contrast, the other selections include grape varieties that are not typically associated with Rhône blends. While Sangiovese, Nebbiolo, and Tempranillo belong to other regions, and the inclusion of Merlot and Zinfandel does not reflect traditional Rhône winemaking practices. Similarly, Carmenere, Malbec, and Pinot Noir are more characteristic of regions like Bordeaux
