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. G3 manages approximately 40% of the wine grape pomace produced in California.
We receive pomace throughout California and transport it to our FSMA-compliant storage and processing facilities in Livingston and Fresno. G3 recovers these winemaking solids to produce high quality GP+ grape pomace as animal feed. Repurposing grape pomace as an animal feed reduces landfill waste and greenhouse gases associated with composting.
G3 sells both dry and wet GP+ wine grape pomace as feed for California dairy cows, beef cattle, and poultry. We sell GP+ 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.Contact Us
