Sustainable Wine Is Less Damaging to the Environment, But How Can You Spot It?
By Melissa Kravitz Hoeffner
Over six gallons of water are required to produce one gallon of wine. "Irrigation, sprays, and frost protection all [used in winemaking] require a lot of water," explained winemaker and sommelier Keith Wallace, who's also a professor and the founder of the Wine School of Philadelphia, the largest independent wine school in the U.S. And water waste is just the start of the climate-ruining inefficiencies commonplace in the wine industry. Sustainably speaking, climate change could be problematic for your favorite glass of wine.
Wine, in all its sippable glory, is, after all, an agricultural product, dependent on several, ever-changing factors that impact the taste, look and longevity of each bottle. The temperature, the weather and the ground (collectively known as the terroir) the grapes are grown in all affect every single bottle of wine. And, like any product that relies on uncontrollable environmental factors, wine is in trouble due to human-caused climate change.
Rising temperatures, droughts, forest fires, natural disasters and other unfortunate, once rare, now increasingly more common, climate-related catastrophes are endangering small and large wineries alike. According to a new study, wine regions across the planet could shrink by more than 50 percent if temperatures rise by 2 degrees Celsius. (One stopgap solution could be for winemakers to switch their grape varieties to those that are more tolerant to drought and heat.)
Not only is our drastically changing planet threatening the wine varietals whose taste the culinary world has come to favor for having specific characteristics, but the industry as a whole is shifting. Popular wines may be harder to produce, or lose their defining characteristics, as the planet changes.
"When your entire business is predicated on the predictability of the weather, any change in climate, hot or cold, has an enormous impact," Wallace said. "You work all year, but if it rains at the wrong time or if fires start nearby, then you forfeit your entire salary for the year. That is a terrifying proposition to anyone." As the director of a wine school, Wallace himself finds that an increasing number of his students are interested in the subject of sustainability and wine. But the topic isn't nearly as clear as a well-washed Schott Zwiesel Burgundy glass.
Sustainability Is Subjective
Sustainability isn't an absolute, meaning that wine and its agricultural counterparts can be sustainable in some ways, and not so much in other facets. While winemaking may be hyper eco-conscious, bottling and shipping may harm the planet beyond what less sustainable vineyard habits could ever lay claim to. Sustainability is rosé; neither white nor red, not necessarily organic or inorganic, but somewhere in between. And that limbo of sustainability can be, like a nicely chilled pink wine, complex and delicious, though nowhere near as easy to sip.
For instance, organically grown and made wine is not necessarily considered to be organic wine. "In the wine industry, many growers farm organically, but to be certified as an organic farm, the grower must keep records of practices for several years and submit them to one of the certifying organizations, like California Certified Organic Farmers," explained Vanessa Conlin, head of wine at online wine store Wine Access.
These etymological (and bureaucratic) hurdles make it difficult for a wine to become officially organic certified, and therefore the organic practices of omitting synthetic fertilizers, pesticides and other toxins from the wine-growing and making process, though better for the environment and the consumer's health, typically go unseen on a wine bottle's label. In France, however, a special European Union regulated label, the Ecocert, marks biological (that is, wines free of artificial pesticides, herbicides and fertilizer) wines, proving that such an indicator can be successfully utilized with a little government interest.
In the United States, organic is the most popular label to identify a biological wine, but wines that are labeled organic also cannot contain any added sulfites. Sulfites are a natural by-product of fermentation, but many winemakers add sulfur dioxide as antimicrobial and an antioxidative agent, stabilizing wines to best ensure the bottle tastes as good as expected once uncorked.
"The key difference between sustainable and organic farming is that while sustainability is meant to protect the environment for future generations, it does not have to include organic practices, although many do," Conlin explained. "Sustainability takes into account the health of the entire business, in ways like water preservation, energy efficiency, and even the well-being of the employees." Biodynamic wine, which utilizes a closed ecosystem, that is, no outside fertilizers or alternative products, is just one example of a type of sustainable wine.
"Every winery and farm can do it," said Art Hunt, who, along with his wife Joyce, founded and owns Hunt Country Vineyards, located near Keuka Lake in the Finger Lakes AVA ("American Viticultural Area," a federally designated wine grape-growing region) in upstate New York. The Hunts regard their vineyard as a total, biodiverse ecosystem that supports bees, birds and other wildlife.
"It's not all or nothing," Hunt said about running a sustainable winery. "You can work at it every year without it impacting your bottom line too much, and gradually increase your profitability."
Sipping Wine Sustainably
The carbon footprint of global winemaking and global wine consumption is nothing to scoff at. The latter, which requires cases of wine be shipped from California to Spain, France to China, Australia to South Africa or perhaps back to Oregon or Alaska and everywhere in between, imprints a deep carbon footprint. Because wine is so region-specific, and only so many regions can create drinkable bottles, ground and air transportation is responsible for nearly all of the wine industry's CO2 emissions.
Pesticides may fall out of favor, but a craving for an excellent Napa Cabernet in Singapore may not. The solution? Better packaging. "Many sustainable producers are making a concerted effort to lessen their carbon footprint by moving to lighter-weight glass bottles, or are trying alternative packaging, as the actual production of glass is energy-intensive," Conlin explained. "Cans, kegs, and other alternative types of packaging are lighter to ship and, in the case of kegs, are often reusable." Wine on tap? Great for the planet!
Unless you're a hyper-knowledgeable wine consumer, actually understanding how to purchase a bottle of wine sustainably can be befuddling. Beyond the physical packaging, labels like Certified California Sustainable Winegrowing, additional local certifications, and the universal Demeter qualification, only for biodynamic wines, can address environmental concerns. "Look for key terms like sustainable or integrated pest management or even biodynamic," Wallace suggested. "They mean a wine was made with the goal to protect and maintain the natural ecosphere."
Also, winemakers use animal-derived products to clarify the wine in a process called "fining." Some fining agents include casein (a milk protein), albumin (egg whites), gelatin (animal protein) and isinglass (fish bladder protein). Since animal agriculture is the second largest contributor to human-made greenhouse gas emissions after fossil fuels and a leading cause of biodiversity loss, deforestation, and water and air pollution, eco-minded, animal-friendly wine drinkers may want to seek out vegan wines, which use mineral-based fining agents like activated charcoal or bentonite, a type of clay.
Wine is a dialogue, and there's no shame in asking a sommelier or wine store professional questions about wine and its sustainable bragging points. Ask which bottles (or cans!) are sustainable or vegan, which winemakers prioritize protecting the environment and if there are any local alternatives to a more faraway favorite.
"Industry buyers and restaurants are there to serve the demands of the consumer, so as interest in sustainability grows, savvy merchants are responding to that demand and often notate sustainably farmed wines on shelf-talkers or as symbols on wine lists," Conlin said. Don't see sustainable notations at your local wine shop or happy hour spot? Speak up!

John Kerry helped bring the world into the Paris climate agreement and expanded America's reputation as a climate leader. That reputation is now in tatters, and President-elect Joe Biden is asking Kerry to rebuild it again – this time as U.S. climate envoy.
Energy Is at the Center of the Climate Challenge<p>The <a href="https://science2017.globalchange.gov/chapter/1/" target="_blank">effects of climate change</a> are already evident across the globe, from <a href="https://theconversation.com/100-degrees-in-siberia-5-ways-the-extreme-arctic-heat-wave-follows-a-disturbing-pattern-141442" target="_blank">extreme heat waves</a> to <a href="https://science2017.globalchange.gov/chapter/12/" target="_blank">sea level rise</a>. But while the challenge is daunting, there is hope. Solar and wind power have become the <a href="https://www.irena.org/publications/2020/Jun/Renewable-Power-Costs-in-2019" target="_blank">cheapest forms of power generation globally</a>, and technology progress and innovation continue apace to support a transition to clean energy.</p><p>In the U.S. under a Biden administration, long-term national climate legislation will depend on who controls the Senate, and that won't be clear until after two run-off elections in Georgia in January.</p><p>But there is no shortage of <a href="https://www.bloomberg.com/features/2020-biden-climate-change-advice/" target="_blank">ideas for ways Biden</a> could still take action even if his proposals are blocked in Congress. For example, he could use executive orders and direct government agencies to tighten regulations on greenhouse gas emissions; increase research and development in clean energy technologies; and empower states to exceed national standards, <a href="https://www.reuters.com/article/us-autos-emissions-california/defying-trump-california-locks-in-vehicle-emission-deals-with-major-automakers-idUSKCN25D2CH" target="_blank" rel="noopener noreferrer">as California did in the past with auto emission standards</a>. A focus on a just and equitable transition for communities and people affected by the decline of fossil fuels will also be key to creating a sustainable transition.</p><p>The U.S. position as the world's largest oil and gas producer and consumer creates political challenges for any administration. U.S. forays into European energy security are often treated with suspicion. Recently, France blocked <a href="https://www.wsj.com/articles/frances-engie-backs-out-of-u-s-lng-deal-11604435609" target="_blank">a multi-billion dollar contract</a> to buy U.S. liquefied natural gas because of concerns about limited emissions regulations in Texas.</p><p>Strengthening cooperation and partnerships with like-minded countries will be critical to bring about a transition to cleaner energy as well as sustainability in agriculture, forestry, water and other sectors of the global economy.</p>
Creating a Global Sustainable Transition<p>How the world recovers from COVID-19's economic damage could help drive a lasting shift in the global energy mix.</p><p>Nearly one-third of Europe's US$2 trillion economic relief package <a href="https://www.bloomberg.com/news/articles/2020-07-21/eu-approves-biggest-green-stimulus-in-history-with-572-billion-plan" target="_blank" rel="noopener noreferrer">involves investments that are also good for the climate</a>. The European Union is also strengthening its 2030 climate targets, though each country's energy and climate plans will be critical for successfully implementing them. The <a href="https://joebiden.com/clean-energy/" target="_blank" rel="noopener noreferrer">Biden plan</a> – including a $2 trillion commitment to developing sustainable energy and infrastructure – is aligned with a global energy transition, but its implementation is also uncertain.</p><p>Once Biden takes office, Kerry will be joining ongoing <a href="https://www.un.org/en/conferences/energy2021/about#:%7E:text=The%20overarching%20goal%20of%20the,2030%20Agenda%20for%20Sustainable%20Development.&text=Accelerate%20delivery%20of%20United%20Nations,related%20issues%20at%20all%20levels." target="_blank" rel="noopener noreferrer">high-level discussions on the energy transition</a> at the U.N. General Assembly and other gatherings of international leaders. With the U.S. no longer obstructing work on climate issues, the G-7 and G-20 have more potential for progress on energy and climate.</p><p>Lots of technical details still need to be worked out, including international trade frameworks and standards that can help countries lower greenhouse gas emissions enough to keep global warming in check. <a href="https://www.carbonpricingleadership.org/what" target="_blank" rel="noopener noreferrer">Carbon pricing</a> and <a href="https://www.csis.org/analysis/how-can-europe-get-carbon-border-adjustment-right" target="_blank" rel="noopener noreferrer">carbon border adjustment taxes</a>, which create incentive for companies to reduce emissions, may be part of it. A consistent and comprehensive set of national energy transition plans will also be needed.</p><p>The global shift to <a href="https://www.irena.org/publications/2019/Jan/A-New-World-The-Geopolitics-of-the-Energy-Transformation" target="_blank">clean energy will also have geopolitical implications for countries and regions</a>, and this will have a profound impact on wider international relations. Kerry, with his experience as secretary of state in the Obama administration, and Biden's plan to make the climate envoy position part of the National Security Council, may help mend these relations. In doing so, the U.S. may again join the wider community of countries willing to lead.</p>

As we approach the holidays I, like most people, have been reflecting on everything 2020 has given us (or taken away) while starting to look ahead to 2021.
