What are the 2 main grape varieties used for rosé in Côtes-du-Rhône, Côtes-du-Rhône Villages, Lirac, and Tavel?

The primary grape varieties used for rosé wines in the Côtes-du-Rhône, Côtes-du-Rhône Villages, Lirac, and Tavel regions are indeed Cinsault and Grenache. Grenache is particularly prominent, known for its ability to produce rosé wines that are fruity and aromatic, with a bright, fresh character. Cinsault complements Grenache by adding floral notes and enhancing the wine's overall balance and complexity.

In contrast, while Merlot and Cabernet Sauvignon are well-known varieties, they are more commonly associated with red wines, particularly from Bordeaux, and are not the mainstays for rosé in the specified Southern Rhône regions. Similarly, Syrah and Mourvèdre, which are important in some contexts, are primarily used for red wines, though they can be found in certain rosé blends; they are not as predominant as Grenache and Cinsault in the listed areas. Lastly, Pinot Noir and Chardonnay are primarily associated with sparkling wines and white wines, particularly from regions like Champagne and Burgundy, rather than the rosé styles characteristic of the Southern Rhône.
