Grape pomace is the material that remains after the grapes are pressed and consists of skins, seeds, and stems. About 80% of the total harvested grape crop goes into wine-making; the remaining 20% is pomace. Traditionally, pomace is being used as a compost and mulch but due to its high nutritive value pomace is making its way to flour, oils, and cosmetics. Pomace contains antioxidant and radical scavenging properties with great potential for natural antioxidant additive for food products and as a dietary supplement.
Some of the successful stories repurposing pomace:
Marché Noir Foods had been using pomace to turn it into wine flour. Some of their products are Pasta Caberneti and Cabernet Brownies. They claim that their approach should be not much about recycling but “rediscovering something of great value that has always been there”.
AprèsVin uses the pomace from winemaking to produce artisanal, varietal grape seed oils and gluten-free grape seed flours.
Caudalie is a French skincare company using grape-seed polyphenos with anti-aging properties in many of its products. During the harvest season in the family vineyard, they realized that “they were throwing away treasures” and with further assistance they develop their patented formula.
Green Paper Works is a startup from India. It produces “grape paper”, handcrafted luxury paper that is tree free and chemical free. It is cost competitive since raw materials are of low cost compared with the traditional alternatives using other fibers like wood, cotton, thread, biomass, etc.
