Roussillon is all too often lumped together with its eastern neighbour, Languedoc. And while the two regions do share similarities—namely warm temperatures and common grapes—there are significant and important differentiators as well. From a cultural standpoint, Roussillon is more Catalan than French, located just over the Pyrenees mountains where the Mediterranean coast runs north before veering east. The climate here is harsh and severe, with extreme heat, minimal rain and a constant, fierce wind, known locally as the Tramontane. The soils are incredibly poor, with barely a trace of earth on top of a hard shale, schist and limestone base. All of these factors combine to naturally create incredibly low yields and, as a result, intense, characterful wines. Low yields and small estates also mean higher production costs. On average, the wines of Roussillon are more expensive than those from Languedoc. They are also a little more demanding for the drinker in terms of profile and style. They are most definitely wines that show best with food; and they usually reward patience, be it via decanter or time in the cellar. But they are some of the most expressive, complex and terroir-driven wines you will find.
