Classified as a Second Growth Bordeaux estate, Chateau Cos d'Estournel is without doubt, one of the top producers in the St. Estephe appellation, producing complex and intense, full-bodied wines. The chateau is often referred to as "super second," meaning that it produces wines at a quality nearing that of the First Growth houses. Cos d'Estournel wines contain a large amount of Merlot (40%), one of the highest percentages in the region, in fact; this gives the wines their wonderful fleshy, chewy texture. The chateau itself is a very unusual pagoda style building which was built by the 19th century owner Louis-Gaspard d'Estournel. The building is featured on the bottle label, making it easy to spot in the Bordeaux section. The estate also produces a second wine called Les Pagodes de Cos.
