The wine’s quality comes from a favourable varried soil - clay-siliceous on the plateau of Guillac and clay-chalk on the hill-sides of Grézillac - as well as ancient methods of farming.

Without the use of chemical fertilizers and herbicides, the wine is treated with manure, seaweed, guano, vine-shoots, green manure and a maximum of humus. Every second row of the vineyard is planted with grasses whereby the planting is effected on alternate rows from year to year.

The leaves of the vine are treated with the ‘Bordeaux Soup’ and flowers of sulphur against the Mildew and Oidium. Green harvest. Grape’s maturity.

Immediate selection on arrival of grapes at the cellar. Separation of the must. Hygienic conditions. Controlled fermentation. Controlled temperature: 18° for the white wines, 20 to 28° for the red wines. Attentive care during the maturing, the blending...

All these stages are very important causes of concern to the winemaker until the wine is bottled.
