Sustainable Transformation
of Wine Grape Pomace
Each year California wineries produce more than 450,000 tons of winemaking by-product materials. As a key partner to the wine industry’s sustainability program, the G3 Ag operation provides a fully-integrated service for grape pomace, also known as grape marc—the discarded grape skins, seeds and stems that remain after pressing.
We receive pomace from the Central Valley and Northern California and transport it to our storage and processing facilities in Livingston and Fresno. Then, using proprietary processing methods, G3 recovers these winemaking solids to produce food products and animal feed.
Grape Pomace
Animal Feeds
G3 sells both wet and dry wine grape pomace as feed for dairy cows, beef cattle, and poultry. We sell pomace feed both domestically and abroad.
Grape pomace provides important dietary fiber, protein content, and antioxidants. Read more about grape pomace for animal feed in these resources:

Culinary Grape Seed Oil
G3 also produces and sells bulk wine grape seed oil. Grape seed oil retains the health-boosting properties of the fruit, including potent antioxidants from the skins and omega-6, a polyunsaturated fatty acid believed to reduce inflammation and boost brain health.
With a high smoke point, grape seed oil is ideal for high-temperature cooking; its clean and light taste makes it a favorite for salad dressings.
