Says Richie Allen, Director of Viticulture & Winemaking, at Napa Green Certified Rombauer Vineyards. Most wine drinkers understand that if you are opening a high-quality wine you will be popping a cork. But somewhere along the way confusion has arisen about the sustainability of cork.
It’s simple – natural cork is the most sustainable wine closure. Did you know that cork is made from the bark of cork oak trees? The bark cannot be harvested until the oak tree is 25 years old, and is then harvested every nine years, using ancient harvesting techniques. The bark harvest actually prolongs the life of the trees, which can live from 100 to 300 years. This is the definition of a sustainable, renewable resource.
Wait, why am I looking at a cat? Cork oak forests spread across 5.4 million acres in the western Mediterranean, and have been recognized by the World Wildlife Fund as one of the 36 top biodiversity hotspots in the world, home to endangered species like the Iberian lynx, the Iberian imperial eagle, and the Barbary deer. In Portugal, the epicenter of corks forests, the trees have been protected since the 1200s. If a cork oak is cut down without permission from the forest service, there are criminal penalties, even if the trees are dead.
And far more than this is protected in these cork forests. The trees serve as a carbon sink. When considering the full life-cycle of a cork, from the carbon sequestered in the forest, to manufacturing and distribution, cork remains carbon negative, or climate positive. 12,000 natural corks offsets as much CO2e emissions as 83 solar panels. In Portugal, the CO2 stored in cork oak forests is equal to 5% of national emissions.
Also protected is a way of life. 95% of cork forests are owned by families or small to medium companies. The method of harvesting cork bark has been handed down from generation to generation, with cork harvesting being the best paid agricultural job in the world. In rural communities where harvesting is a specialty, often 3-5 people in each family work together to harvest the cork bark.
So, what about those screw caps and synthetic corks? Most metal screw caps have a plastic liner and there are no recycling facilities in the U.S. that can recycle them. They all end up in landfill. Similarly, plastic closures, made from fossil fuels, are not biodegradable and are rarely recycled. Significantly more energy, water, waste generation, and greenhouse gas emissions are required to make these wine closures.
One area where we can all do better is cork recycling. Cork is absolutely recyclable, but we have to get those little corks to the recycling groups like ReCORK and Cork ReHarvest. Many communities have convenient dropoff locations. Here is Napa we bring them to our local Whole Foods. By this time next year, you could be wearing shoes with soles made from your corks.

Napa Green is a global leader in sustainable winegrowing, setting the highest bar for sustainability and climate action in the wine industry. Napa Green facilitates systematic soil to bottle certification for wineries and vineyards, and provides the resources, tools and connections to continuously level up leadership. In 2021, Napa Green was the first sustainable winegrowing program in the world to redevelop Vineyard certification standards to focus on climate action, regenerative carbon farming, and social equity. In 2022, Napa Green and community partners launched the first of its kind, six-event RISE Climate & Wine Symposium (formerly THRIVES) with over 65 leading speakers and 40 “Sustainable Services & Solutions” partners and sponsors.
Take action this Earth Month with Napa Green. Our team of experts is ready to assist you in achieving your climate action goals for both your vineyard and winery, no matter where you are in your sustainability journey.

🍴Wednesday April, 23rd is the day NOT to miss lunch at @cliffamily!!
Come enjoy delicious food while supporting Napa Green! See you there.
Uniquely, Napa Green isn’t just a roadmap of leading practices. Napa Green provides an expert, boots-on-the-ground consulting team that develops:
✅ Regenerative Carbon Farm Plans (to enhance soil health, biodiversity, resilience, and carbon storage)
✅ Irrigation Distribution Uniformity Assessments (to maximize water efficiency)
✅ Integrated Resource Assessments (to reduce energy, water, waste and emissions in production)
✅ Action Plans for continuing improvement (tailored to the opportunities and goals of each vineyard or winery)
Additionally, we support soil sampling and analysis, provide resource assistance, run practical training and education workshops throughout the year, and provide valuable, hands-on guidance in meeting your climate action goals.
✅ Napa Green members implement over 120 best practices in both the Vineyard and Winery. This Earth Month, learn about 21 of them with “21 Days, 21 Ways” counting down to Earth Day.

Napa Green’s vineyard team is trained to develop regenerative, whole-farm Carbon Farm Plans (CFPs). These plans review all of the current beneficial practices that are increasing soil and ecosystem health and storing carbon, and identify additional opportunities to regenerate the soil and vineyard ecosystem and simultaneously maximize carbon capture in a given property. Each vineyard’s goal is to become carbon neutral (or negative) and increase the resilience of vineyards, businesses, and our community.

Forests are not only our largest terrestrial carbon sink, they are also home to 80% of the world’s on-land diversity. We need healthy forests, which means a balanced density of native trees and plants. Healthy forests experience lower intensity fires with less tree mortality, meaning higher carbon retention and ecosystem function.

All of our members are committed to using at least 60% renewable energy, whether through on-site solar and other renewable sources or by working with @mcecleanenergy to access clean power through the grid. The impact? Over 1.2 million pounds of CO2e saved by wineries and vineyards in just one year. To put that into perspective it’s the equivalent to offsetting the emissions from driving over 1.5 million miles in a typical gas-powered car!

Napa Green Certified Vineyards implement climate-smart burn practices, such as Conservation Burning, Flame Cap Kilns, and Air Curtain Burners. These practices reduce smoke and emissions and create biochar. Biochar is re-fossilized wood that provides long-term carbon storage. Even more compelling, when inoculated and applied with compost, biochar aids in water retention and increases water and fertilizer efficiency.

While vineyards don’t directly require pollination, pollinators still play a vital role in the overall health of our ecosystems. Increased biodiversity leads to better soil health, water retention and can attract beneficial insects. Plus, pollinators are friend shaped! 🐝
