For those who read my regular articles, you probably know I'm a fan of Sancerre's satellite appellations. What exactly are the satellites? These neighboring regions share many of the same geological foundations as Sancerre and are planted predominantly to the same noble grape—Sauvignon Blanc. The most famous is Pouilly-Fumé, directly across the Loire River, but appellations like Quincy, Reuilly, Coteaux du Giennois, and today's featured region, Menetou-Salon, have become some of the Loire's best sources for exceptional value. In fact, Menetou-Salon is the only satellite appellation that directly borders Sancerre—you could almost imagine the appellation continuing seamlessly across the boundary. Much of Menetou-Salon is planted on Terres Blanches, the same calcareous marl rich in fossilized oyster shells that forms one of Sancerre's three great soil types, alongside Caillottes (limestone) and Silex (flint). While Terres Blanches accounts for only about a third of Sancerre's vineyards, it consistently produces some of the region's most structured and age-worthy wines. It's no surprise that the same soils give Menetou-Salon wines their signature depth and texture. Domaine Fournier is best known for its outstanding collection of single-terroir Sancerres, but the family also farms one of Menetou-Salon's finest vineyards, the Côte des Morogues, where Terres Blanches and clay dominate the landscape. The result is a Sauvignon Blanc with impressive concentration and weight, offering layers of ripe grapefruit, passion fruit, and wild thyme, all wrapped around a beautifully mineral core. Clean, precise, and remarkably expressive, it's another reminder that some of the Loire's best values are often found just beyond Sancerre's borders.
