Now a completely separate entity from Leoville Las Cases, Clos du Marquis is produced from Las Cases vineyards, but only from those that are outside the famous walled sector (referred to as Le Clos), which are reserved for Leoville Las Cases. The 2011 Clos du Marquis, which is meant to compete with second growths, possesses a dark ruby/plum color along with classic black cherry and black currant fruit intermixed with hints of minerality and spice. This pure, medium-bodied, well-endowed beauty can be drunk over the next 10-15 years.
The name of this wine, created at the beginning of the 20th century when the vineyard was planted, was inspired by the Petit Clos adjacent to the Château de Leoville, residence of the Marquis de Las Cases. Clos du Marquis is a historical brand by the Domaines Delon, a separate vineyard to Leoville Las Cases whose first vintage was released in 1902. The creation of this brand was to allow a clear identification of two completely distinct terroirs.
The situation remains unchanged today as the vineyard producing the Clos du Marquis is located on top terroirs of the Saint Julien appellation, surrounded by such prestigious Classified Growths as Leoville Poyferre and Leoville Barton.
