Our commitments: independent winegrower, high environmental value and organic farming

Being an independent winegrower is a real philosophy. The same passion drives independent winegrowers: to produce wines that respect the environment and society.

This means being in constant search of excellence in terms of methods and results. This is what we implement while respecting HVE and BIO standards and also through our management of the estate, promoting the right balance between the terroirs, grape varieties and winemaking methods.

This also means an eco-responsible approach where we promote short circuit distribution, directly to the consumer. We present all our wines for tasting at most wine fairs in France, which allows us to be closer to our customers, to gather their opinions and impressions and to deliver them on site at each of these events. Of course, it is also possible to buy our wines directly at the château, during your visits or on our website.

Château Le Porge, through the SIRAC family, has been part of the Independent Winegrowers since 1990.

The High Environmental Value (HVE) guarantees that the agricultural practices used on our entire farm preserve the natural ecosystem and minimize the pressure on the environment (soil, water, air, landscape, etc.). The HVE rating is based on environmental performance indicators for the operation. It is based on four themes:

• Preservation of biodiversity (insects, trees, hedges, grass strips, etc.)

• The phytosanitary strategy

• Fertilization management

• Water resource management

We implement agricultural practices based in particular on the principles of agroecology. It is about favoring the resources and mechanisms of nature.

Operational autonomy, improvement in the added value of products, reduction in energy consumption, reduction in plant protection products ... High Environmental Value (HVE) corresponds to the highest level of the environmental certification system for agricultural operations.

5,399 French farms benefit from the “HVE” label (as of January 1, 2020) including Château Le Porge.

Wines certified organic farming are subject to specifications specific to organic farming. These specifications revolve around two main areas: the cultivation of grapes in the vines and winemaking techniques in the cellar.

The grapes are therefore grown without the application of synthetic products to the vineyard, without fertilizers or chemical weeding. The agricultural raw materials of the products of the wine sector are 100% organic: grapes, sugar, alcohol, rectified concentrated mout….

Also the wines are produced without recourse to certain oenological practices. The regulations provide for a limitation or prohibition of certain oenological practices.

The prohibited practices are as follows: Partial concentration by cold (enrichment) - Elimination of sulfur dioxide by physical processes - Treatment by electrodialysis (tartaric stabilization of wine) - Partial dealcoholization of wines - Treatment with cation exchange resins (tartaric stabilization) - Electrodialysis (tartaric stabilization) - Electro-membrane treatment, membrane coupling and contactors - Use of filter plates (Zeolites)

The practices subject to restriction are as follows: Heat treatments ≤ 70 ° C - Centrifugation and filtration ≥ 0.2 microns - Reverse osmosis: Enrichment of musts by subtractive method only - Ion exchange resins: Process for the elaboration of MCR (Mout Concentrate Rectified) only.


Château Le Porge started its BIO-Agriculture approach in 2019. Currently in phase 2 of the conversion to organic farming, Château Le Porge will benefit from final certification in 2023.
