Geography
Saint-Julien sits on the Médoc peninsula between Pauillac to the north and Margaux to the south. The vineyards are concentrated on deep gravel mounds (croupes) running along the Gironde estuary, particularly the famous Saint-Julien gravel terraces that give the appellation its remarkable consistency. The maritime influence is significant; the river protects the vineyards from spring frost.
Classification
No First Growths, but Saint-Julien has the highest concentration of Second Growths of any Médoc commune: Léoville-Las Cases, Léoville-Poyferré, Léoville-Barton, Ducru-Beaucaillou, Gruaud-Larose. Plus serious Third Growths (Lagrange, Langoa-Barton) and Fourth Growths (Branaire-Ducru, Beychevelle, Saint-Pierre, Talbot). The classification hierarchy reads almost like a top-25 list of serious Médoc châteaux.
Style of the wines
Saint-Julien wines split the difference between the structured, tannic, sometimes austere style of Pauillac and the more aromatic, immediately approachable style of Margaux. The classic profile: black currant (cassis), cedar, graphite, tobacco, dark plum, sometimes a leathery savoriness in older examples. Tannin is firm but ripe; acid is bright; alcohol typically 13-13.5%. The wines are widely considered the most balanced and food-flexible of the Médoc.
How they age
Top Saint-Julien Second Growths from a good vintage age thirty to fifty years routinely. Léoville-Las Cases in particular is one of the longest-lived Médoc wines and is often described as 'super-second', drinking and pricing at First Growth level. The 2010, 2005, 2000, 1996, 1990, 1986, 1982 are all legendary Saint-Julien vintages.
Producers we know
