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. G3 manages approximately 40% of the wine grape pomace produced in California.
G3 receives pomace from winery facilities across California and transports it to G3's Food Safety Modernization ("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.
Feeds & Pomace Sustainability
We collect and repurpose over 40% of the California winery grape waste for animal feed, an average of 175,000 tons a year.
Grape Pomace Animal Feeds
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, and antioxidants. Read more about grape pomace for animal feed in these resources:
