One of the six famous communes (along with Listrac-Médoc, Margaux, Moulis, Pauillac and Saint-Estèphe) within the French Haut-Médoc area that are appellations in their own right and are allowed to use the commune name on the bottle label. The communal appellation also includes the neighbouring commune of Beychevelle. The vineyards cover around 900 hectares of vines in an almost square shape. A special feature is that there is a 16-hectare enclave in the municipality whose wines are allowed to bear the Pauillac designation of origin. It is also worth mentioning that historically, the famous Château Latour (Pauillac) would actually belong to Saint-Julien. The soils consist of a thin layer of gravel with sandy loess on an iron-rich subsoil with marl and gravel.
