UDM is composed of 6 production sites and 6 subsidiaries. We are leaders in the processing and marketing of by-products of vine. Our purpose is to support the winegrowing sector. The values of cooperation drive our efforts, and it is with pride and responsibility that we give a “second life” to our grapes. Our 6 sites are organized around a succession of workshops that treat the products and by-products of vine in order to extract different elements: alcohol, calcium tartrate, seeds, pulp, compost and liquid fertilizers.
