2017 Cos d'Estournel Blanc, Bordeaux

Cos d'Estournel

Château Cos d`Estournel is named after its 19th century owner, Louis-Gaspard d'Estournel, and it was he who built the bizarre oriental edifice that is a landmark for any tourist in the Médoc. Today Cos d'Estournel is without doubt the leading estate in St-Estéphe. It is located in the south of the appellation on the border with Pauillac and its vineyards are superbly sited on a south-facing gravel ridge with a high clay content, just north of Lafite.

Cos d'Estournel is typically a blend of 60% Cabernet Sauvignon, 38% Merlot and 2% Cabernet Franc - do not be fooled by the relatively high Merlot content, as these are full-bodied, dark, brooding tannic wines when young which develop a complexity and intensity that can rival many top growths from Pauillac.

In 1998 the Prats family sold Cos d'Estournel to The Tailan Group. Cos d'Estournel is classified as a 2ème Cru Classé.

Saint-Estèphe

Saint-Estèphe is the northernmost of the most important communes of the Médoc and borders Pauillac on its southernmost border, with only a gully and stream separates it from Ch. Lafite. To the north lies the Bas-Médoc.

Saint-Estèphe is defined by the depth of its gravel, which is ubiquitous but of varying depths and occasionally very shallow, when clay predominates. This keeps the soil cooler and wetter than its counterparts so that the wines can appear fresh in lighter vintages, but superbly successful in hot, dry years. 

The best châteaux in the south of the commune have the deepest soil and the thickest gravel. Cos d'Estournel has an exceptional terroir with its vineyards being located on a south-facing ridge of gravel with excellent drainage. 

Saint-Estèphe is the least gravelly of main Médoc communes and in the north of the commune the vineyards are heavier and more clay-based leading to a rustic style of wine being produced.

The wines can appear austere in youth with a discernable ferric note at some châteaux, but the best typically display good depth of colour, pronounced acidity an tannins in youth and are exceptionally long-lived. At their best, they are the equal of almost any Bordeaux. The well-regarded St Estèphe co-operative controls the production of about half the appellation.

Sauvignon Blanc

An important white grape in Bordeaux and the Loire Valley that has now found fame in New Zealand and now Chile. It thrives on the gravelly soils of Bordeaux and is blended with Sémillon to produce fresh, dry, crisp  Bordeaux Blancs, as well as more prestigious Cru Classé White Graves.

It is also blended with Sémillon, though in lower proportions, to produce the great sweet wines of Sauternes. It performs well in the Loire Valley and particularly on the well-drained chalky soils found in Sancerre and Pouilly-Fumé, where it produces bone dry, highly aromatic, racy wines, with grassy and sometimes smoky, gunflint-like nuances.

In New Zealand, Cloudy Bay in the 1980s began producing stunning Sauvignon Blanc wines with extraordinarily intense nettly, gooseberry, and asparagus fruit, that set Marlborough firmly on the world wine map. Today many producers are rivalling Cloudy Bay in terms of quality and Sauvignon Blanc is now New Zealand`s trademark grape.

It is now grown very successfully in Chile producing wines that are almost halfway between the Loire and New Zealand in terms of fruit character. After several false starts, many South African producers are now producing very good quality, rounded fruit-driven Sauvignon Blancs.
