The sustainable development establishes an approach, a process of evolution, which meets the needs of the present without compromising the future.
In the contact of the nature, we work on it on everyday life!

Guillaman - Produit Bio

A new step was taken in 2017 with the certification of our winery as a Haute Valeur Environnementale (HVE) de niveau 3.

This environmental certification of farms meets the need clearly expressed in the work of the « Grenelle de l'environnement » to recognize farms engaged in particularly respectful approaches to the environment.
Level 3 reflects a level of excellence in the environmental performance of the farm; the specifications are strict and periodically checked by an independent certifying department approved by the Ministry of Agriculture. Level 3 is based on an obligation of results with indicators measuring the performance of the operation.

This certificative approach is only the formalization of the good environmental practices that we practice on a daily basis :

Our daily commitment translates into the production of « clean » vintages, which are free of any residue.

Each year, our different vintages are subjected to residue analyses of plant protection products, carried out by an accredited testing laboratory.

Alternative phyto strategy

For over 5 years, our winery has exclusively used tunnel spraying. This technique economizes 50% of products used and protects the environment. This is the principal point of the Ecophyto plan.

We currently use over 30% biocontrol products and this figure is increasing each vintage. Biocontrol is a natural set of plant protection methods. To control unwanted insects, we choose to use sexual confusion rather than insecticides

Naturals fertilizers

Soil and leaf analysis help to quantify our needs.
Vine shoots are mulched on site which brings organic matter naturally to the soil, 100% of fertilizers used in our vineyard are of natural origin.

Conservation of water resources

No part of our vineyard is irrigated. The annual rainfall is 600mm, with a sustainable viticulture, there is no need for additional water

To produce a liter of wine from start to finish, we require considerably less than one liter of water.

All our wine is treated independantly and on site

Protection of biodiversity

60% of the vineyard is covered with permanent plants (natural meadow, alfalfa).

More than 15% of our vineyard is classified as an area of ecological interest (trees, hedges, groves, fallow land).

For every hectare of vines planted, we have preserved nearly 100 meters of hedges.

We will continue these commitments to sustainable development by planting some 50 trees ans more than 500 meters of local tree hedges on the edge of our vineyards each year.
