2016 Château Sociando-Mallet, Haut-Médoc, Bordeaux

The most widely planted grape in Bordeaux and a grape that has been on a relentless expansion drive throughout the world in the last decade. Merlot is adaptable to most soils and is relatively simple to cultivate. It is a vigorous naturally high yielding grape that requires savage pruning - over-cropped Merlot-based wines are dilute and bland. It is also vital to pick at optimum ripeness as Merlot can quickly lose its varietal characteristics if harvested overripe.

Despite being as visually unprepossessing as the rest of the Médoc, this large red-wine appellation is home to some of the world’s greatest wines. Its 4,500 hectares of vineyards form a largely continuous strip that follows the Gironde from St Seurin-de-Cadourne to Blanquefort. All the great communes of the Left Bank fall within its boundaries: Margaux, St Julien, Pauillac and St Estèphe.

Chateau Sociando-Mallet is an outperforming Cru Bourgeois property located in the commune of Saint-Seurin-de-Cadourne in the Haut-Médoc. Quality was inconsistent until the property was purchased by Jean Gautreau in 1969. It then consisted of only 7 hectares and in the last 30 years Jean Gautreau has expanded the vineyards to 57 hectares. The vineyards, which lie close to the Gironde Estuary, are planted with Cabernet Sauvignon (60%), Merlot (25%), Cabernet Franc (25%) and Petit Verdot (5%). The grapes are hand picked and then fermented in a combination of stainless steel and concrete tanks. The wines are matured in oak barriques (70-90% new) for 12-15 months. They are bottled unfined and unfiltered. These are weighty, firm and well-structured clarets that are typically rich in fruit and have excellent ageing potential. As Jean Gautreau says: "I have a superb terroir which I want to express in the wine. I try to make a classic Médoc for long keeping."
