The varied nature of the region's soils is conducive to the production of fine wines. The "terroir" surrounding Château Vrai Caillou is limestone-based. Vines, whose roots lie deep in the soil, flourish in this balance between the coolness of the clay and the filtering properties of limestone.
The soil around Château Vrai Caillou therefore lends itself perfectly to the blend of skillfully selected grape varieties. The vineyards produce roughly 30% white and 70% red. The white wine is made up of 65% Sauvignon, one of the best French grape varieties, which is itself made up of 40% Sauvignon Blanc and 25% Sauvignon Gris. Whilst the Sauvignon Gris variety is similar to Sauvignon Blanc, its grapes differ in that their skin is pink. An early wine with musts (freshly pressed grape juices) which are rich in sugar, the Sauvignon Gris is scarcely used in the region as it is a low-yielding variety. Its aromas, however, of passion fruit and lychee, which explode with flavour on the palate, are pleasantly fresh due to these exotic notes of unfamiliar fruit. The white wine's remaining 35% is completed with the Sémillon variety which adds fullness and ensures a good yield.
As for the red wines, the vineyards have 55% Merlot, a red variety characterised by small dark red grapes, traditionally used in the Bordeaux region. This variety develops particularly well in limestone-based soils. The other varieties which make up the rest of the reds are 25% Cabernet Sauvignon, one of the key Bordeaux varieties, known for its high quality and 20% Cabernet Franc.
