One of the best-run estates in the underrated and undervalued appellation of Cotes de Castillon is Chateau d’Aiguilhe, which is owned by Stephan von Neipperg. As with all of von Neipperg’s wines, Stephane Derenoncourt is the consulting winemaker. The blend is usually 80% Merlot and 20% Cabernet Franc, although I did not see the statistics on this particular vintage. The 2010 (10,000 cases produced) achieved 14% natural alcohol from modest yields of 34 hectoliters per hectare. It exhibits a deep ruby/purple hue, lots of cassis, crushed rock and floral characteristics, a round, generous, savory, broadly textured style and sweet tannins. Drink it over the next decade.
