Research programmes

Experimental Vinification at ICV  Group

To benefit from the synergies of the most innovative techniques, the ICV Group develops partnerships with private companies or research organizations. Many R & D programmes are initiated within the framework of associations or collaborative programmes.

We present below an overview of key projects pursued or initiated during the past season:

Valuation of tolerant varieties (RESVIN)

Objective: identify varieties tolerant or disease-resistant products in Europe, assess their potential for identifying those to be the subject of an implementation study in France.

Partners:

Co-financing: Project Agreement State Region

This work resulted in the publication of the Technical Guide of resistant varieties .
Optimization of Grape juice industry (FIJUS-Raisol)

Objective: To develop a new range of grape juice with improved nutritional value: reduced in sugar content, rich in polyphenols,with controlled acidity. This objective also involves the need to establish an industry dedicated to grape juice from the Languedoc-Roussillon.

Partners:
