The Domaine de Rocheville has been certified Organic Agriculture since 2019 (after 3 years of conversion) and was previously certified Terra Vitis (Living Earth) since 2011, a label that ensures respect for life from the vine to the bottle.
The soil is worked mechanically to avoid the use of herbicides, the plots benefit from natural grassing which improves the richness and structure of the soil, and a range of measures aim to protect the biodiversity (planting of hedges, roses, etc.).
Finally, the vines are subject to various types of care (short pruning, disbudding, green harvesting) aimed at limiting production and increasing the quality of the grapes.
The vines that give birth to the La Favorite, are around 50 years old, produce around 60hl/ha whereas the average yield of the AOC Crémant de Loire is 74hl/ha.
