Today the Estate consists of 78 hectares of vineyards.
The 47 hectares which surround the Château, the heart of the estate, are called "l'Enclos". Only the grapes from these 47 ha make the "Grand Vin de Château Latour". This vineyard has a typical Médoc topography, with a gentle rise in the ground, bounded on the north and south by two small streams, and on the east by the "Palus", the low lying meadows by the river. But this "Enclos" benefits from a very unique terroir that combines an optimized sub-soil nutrition for the vines, the Gironde river which tempers extreme weather conditions, and a typical Médoc climate, largely influenced by the Atlantic ocean, which allows the grapes to reach maturation under favourable conditions.

This combination, a true gift of Nature, determines the personality and the characteristics of the wine of Château Latour. It also imposes, almost naturally, a selective choice of grape varieties :

There is, first of all, a perfect association between the Cabernet Sauvignon and this terroir, as it represents around 80% of the total planted. This grape variety manages to take the best out of this poor gravels soil by digging deep to its ressources and water, in the layers of clay underneath. This very selective nutrition will naturally bring concentration, deep colour and tannic structure to the wine.

The Merlot represents 18% of the Grand Vin, and plays an important role in regulating and softening the Cabernet Sauvignon. It is planted mainly on the lower parcels of the "Enclos", where the gravels layers are a little less deep, and where the marls and clay layers can be reached more easily by the vines. This will bring roundness and power to the final wine.

Two other grape varieties, the Cabernet Franc and the Petit Verdot for 2%of the total planted vineyard, and are in most cases mixed in with the parcels of Cabernet Sauvignon and Merlot.
