Château GAZIN's vineyard covers an area of 26 hectares, in a single holding, on the upper terrace of the Pomerol terroir.
The terroir at Château Gazin consists of Gunzian gravel on the surface and a subsoil of blue and green clay with iron oxides (iron residues).
As is characteristic of great terroirs, these clays (smectites) ensure that the vines have a reasonably stable supply of water.
Château GAZIN's terroir essentially consists of the clay-gravel subsoil of the Pomerol plateau.
The vineyard is planted with 90% Merlot, 7% Cabernet Sauvignon and 3% Cabernet Franc.
The average age of the vines is 35 years. The vines are planted with a density of 5,500 to 7,000 per hectare.
The vines are cultivated using traditional growing methods and an environmentally-friendly approach with ploughing, organic fertilizers, minimum use of pesticides (including mating disruption), and manual harvests.
