Environmental grape growing techniques are implemented on the three estates.
The use of organic fertilisers is adjusted to the vineyard's needs. High plantation densities allow the roots to develop and help to regulate the yield. The soils are tilled to allow the roots to grow deep into the soil and in order for the vine to benefit from the terroir's natural resources.
Pierre tries to make sure that the phenolic maturity of the grapes is achieved around the same time as their alcoholic maturity. The implementation of leaf-fining and green harvesting increases the foliage exposed to the sunlight, thereby directly influencing the wines' structure and color.
