Bellecoste’s Green Lung

Do you feel this freshness?

It’s a sign of the health and balance of this place. You are in the heart of the Bellecoste Valat, a place that offers food, water, and shelter, as well as a stable temperature for many animals and plants for hundreds of years. As the green lung of this peri-urban area, it contributes to environmental preservation, notably thanks to its continuously flowing water source.

This Valat has two major impacts on our vineyards:

  • It stores a significant amount of carbon in the soil.

An old tree has a better carbon storage capacity than a young tree. The more a tree undergoes photosynthesis, the more it develops its leaves and roots, and this growth in turn leads to increased photosynthesis. The larger the tree, the more carbon it stores. It’s the virtuous cycle of nature. As an old Valat, home to many ancient trees, its ability to sequester carbon in the soil is very stable.

  • It reduces the vine’s water stress.

Beyond the fact that the vines benefit from neighboring species living in the Valat, they also benefit from its humidity. When it gets too hot and the air is too dry, vines experience “water stress.” Just like for humans, the sensation of heat is more important for the plant than the actual temperature, and the air’s humidity created by the Valat reduces the stress experienced by the vines.


A tree is composed of 50% water and 25% carbon. A single tree absorbs between 10 and 40 kg of CO2 per year on average. This is equivalent to a little more than a round trip from Marseille to Nîmes by car. Of course, the CO2 absorption capacity of each tree varies depending on the species and type, age, climate, brightness, and soil nature.
