PR NEWSWIRE | Cork Collective
California wineries join high-profile leaders in wine, spirits, hospitality, and design to support sustainability initiative focused on cork stopper collection and recycling.
SAN FRANCISCO, May 13, 2025 /PRNewswire/ — The Cork Collective, a sustainability-focused nonprofit committed to harnessing the power of cork recycling, has expanded its mission to California. In partnership with leading wineries, the organization is launching a cork collection and recycling program designed to advance eco-conscious practices across the state. Together, the Cork Collective recycles wine corks, helping transform used cork into valuable, eco-friendly products that showcase the material’s versatility and circular potential. These initiatives not only reduce waste but also support meaningful community projects, including resurfacing of playgrounds in public housing and city parks.
With support from esteemed California wineries such as Charles Krug, Ehlers Estate, Priest Ranch, and Pine Ridge, the Cork Collective is proving to be a powerful yet accessible way for the wine trade to elevate its sustainability credentials. The recycling program makes it easy for wineries to engage guests through tasting room participation, where visitors are encouraged to drop off used wine corks in dedicated Cork Collective bins. The initiative also offers a platform for retailers, restaurants, and hospitality venues. By creating a direct link between the wine trade and consumers—from industry leaders to everyday wine lovers—cork recycling becomes part of the wine experience and a shared opportunity to reduce waste and drive meaningful change.
“As the first California winery to partner with the Cork Collective, Ehlers Estate reaffirms its commitment to sustainability and its strong ties to community,” says Steven Folb, General Manager of Ehlers Estate. “This collaboration reflects our dedication to preserving valuable resources and fostering meaningful connections. Giving used corks new life is both an artistic and sustainable act, aligning perfectly with our estate’s holistic vision.”
Further strengthening the program’s foundation in California, the Cork Collective is collaborating with Napa RISE – Napa Valley’s leading coalition for sustainability and climate action in the wine industry. This partnership brings together deep expertise in sustainable practices and cork innovation, helping to engage the regional wine community while offering tools and education to support long-term impact. The Cork Collective is creating a scalable model for cork recycling that not only supports the environment, but also empowers local communities and businesses to take part in a more circular future.
“As a multi-generational, family-owned winery, Charles Krug is deeply committed to sustainability and environmental stewardship,” says Riana Mondavi, Co-Proprietor of Charles Krug Winery. “We’re proud to partner with the Cork Collective at our historic Napa Valley estate to recycle natural corks—giving them new life as safe, eco-friendly playgrounds for children across the country. Together, we’re helping preserve the planet, one cork at a time.”
Cork oak forests play a vital environmental role, absorbing so much CO2 annually that wine cork stoppers can be produced with a negative carbon footprint. Harvested by hand from the bark of cork oak trees, cork is a 100% natural, renewable resource that regenerates without harming the trees, which can live for over 200 years. Despite its sustainability, less than one percent of corks are recycled each year. While corks do biodegrade in landfills, the 13 billion produced annually, highlight a massive opportunity for circular value capture and upcycling.
“Sustainability is at the core of our company’s ethos. Every day, we strive to eliminate any kind of single-use product and actively purchase items in our business that can be recycled, reused, or composted. Our partners at Cork Collective embody this culture and what they are doing with cork is a model for which all of us can embrace,” says Judd Wallenbrock, President & CEO of Priest Ranch.
