Château Carignan is located at Carignan de Bordeaux, 10km East of Bordeaux. The dominant grape variety, as for the other right bank appellations (Saint-Emilion and Pomerol), is Merlot. This variety thirves on the clayey limestone hillsides and offers supple, well-rounded and highly fruity wines. The estate covers 150 hectares, 65 of which are planted with vines. The vines lie on south facing clayey-limestone hillsides covered with stony gravel. 30% of the vineyard is over 40 years old and 70% between 8 and 25 years old. The grape varieties planted are 65% Merlot, 25% Cabernet Sauvignon and 10% Cabernet Franc. A herd of cows ensures a supply of totally organic fertiliser. The grapes for Château Carignan wines are hand harvested. Sorting tables and a private winery with small heat controlled tanks ensure full control of parcel selection for wine making. The entire production is estate bottled. A waste water treatment unit has been in use since the 2000 harvest. The Premières Côtes de Bordeaux AOC (Appellation d'Origine Contrôlée) was defined by the French government in 1937 as an area of 3,400 hectares spread over 37 communes on the right bank of the river Garonne, forming a narrow strip of vineyards some 60km long and 5km wide from the north of Bordeaux to Langon.
