Sustainability and Biodynamics: The Hidden Ecosystem in Your Wineglass

The world of kosher wine has embraced transformative approaches to viticulture that honor both ancient traditions and forward-thinking environmentalism. Sustainability isn't just a marketing term—it's a comprehensive philosophy that encompasses water conservation, solar energy, and holistic management, returning waste to the soil as nourishment. These practices create closed-loop systems where nothing is wasted and everything contributes to vineyard health.

Even more fascinating is biodynamics, which incorporates cosmic rhythms into agricultural science. Biodynamic winemakers plant and harvest according to lunar cycles, bury cow horns filled with manure underground through winter, and use specialized herb preparations to stimulate vineyard vitality. While these practices might sound magical, prestigious estates like Château Pontet-Canet in Bordeaux (which produces remarkable kosher wines) have abandoned tractors for horses and embraced these methods with stunning results—wines of greater vibrancy, complexity, and sense of place.

The next time you raise a glass of sustainable or biodynamic wine, pause to consider what you're truly experiencing. Beyond flavors and aromas lies an intricate story of stewardship, intention, and care—a wine that connects you to something larger than yourself.

Welcome to The Kosher Terroir. I'm Simon Jacob, your host for this episode from Jerusalem. Before we get started, I ask that, wherever you are, please take a moment and pray for the safety of our soldiers and the safe return of all of our hostages. Welcome back to The Kosher Terroir, the podcast where we explore the hidden stories behind the wines you love. I'm your host, simon Jacob, and today we're taking a closer look at something that goes beyond the bottle. We're taking a closer look at something that goes beyond the bottle, beyond labels and accolades. We're talking about the roots of wine, literally.

Solomon Simon Jacob: 0:56

In this episode, we dive into the movements of sustainability and biodynamics in winemaking. These aren't just buzzwords or fleeting trends. They represent deep, intentional choices made by wineries across the globe. But what do these terms really mean? What do they look like in action and how do they affect the wine we enjoy and the world we live in? From Bordeaux to Israel, from California to Spain, we'll explore how wineries are cultivating more than just grapes. They're cultivating ecosystems, philosophies and trust. We'll look at the science, the spirit and the tangible benefits these practices bring to both the planet and the palate. So pour yourself a glass, settle in and let's journey together into the heart of sustainability and biodynamics in the world of wine. Let's start by unpacking two big terms sustainability and biodynamics. They often get used interchangeably, but they are distinct, though sometimes complementary. Sustainability in winemaking is about more than just being green. It's a comprehensive, science-driven approach focused on minimizing harm while maximizing long-term efficiency and ecological balance. At its core, sustainability asks a winemaker to consider every stage of production, from the vineyard to the bottle, and to ask how can we do this in a way that protects the environment, supports the people involved and ensures quality for generations to come? Let's start in the vineyard.

Solomon Simon Jacob: 2:41

One of the biggest concerns in modern agriculture is water use, especially in drought-prone regions like California, chile and Israel. Sustainable wineries often employ drip irrigation systems, originally invented in Israel to precisely deliver water at the base of each vine, using sensors and weather-based data to irrigate only when absolutely necessary. Some wineries go even further by implementing dry farming, relying entirely on natural rainfall to force vines to dig deep roots, improving both resilience and flavor complexity. Energy efficiency is another major focus. Many wineries now power their operations using solar panels, reducing reliance on fossil fuels. Many Israeli wineries, for example, have generated over 85% of their power needs from solar energy. Others use gravity flow winemaking systems to eliminate the need for pumps, reducing electricity usage while also being gentler on the wine.

Solomon Simon Jacob: 3:52

Sustainable wineries also make efforts to manage waste holistically. Rather than sending grape skins and seeds to landfills, they compost and reuse it as organic matter to enrich vineyard soil. Some even convert waste into biofuel or livestock feed. In terms of biodiversity, sustainability often means treating the vineyard as part of a larger ecosystem. Many wineries plant cover crops like mustard beans or clover between vine rows, though in kosher vineyards, they need to carry out such planting appropriately to avoid concerns of Jewish law prohibition against mixing species, and it encompasses several areas, including plants, animals and garments. When it comes to plants, the Torah prohibits sowing certain types of seeds together or planting them too close to one another. This falls under the mixing of different species in agriculture. When done appropriately, though, these plants prevent erosion, replenish soil nutrients and attract beneficial insects that act as natural pest control. Birds, bees, sheep and even bats are welcomed into this micro-ecosystem, maintaining balance without the use of chemical pesticides. Crucially, sustainability is about people, too. Social equity and fair labor practices are integral to the model. That means providing fair wages, safe working conditions and health benefits for vineyard workers, many of whom have historically faced harsh conditions. Some wineries invest in education and housing for farmworker families. Others, in South Africa and Australia, support community cooperatives and development initiatives to ensure wine profits, help build thriving local economies.

Solomon Simon Jacob: 5:55

And sustainability doesn't end in the field or the cellar. It continues through packaging, distribution and community involvement. Lighter weight glass bottles reduce carbon emissions during shipping. Alternative closures like recyclable corks or screw caps made from renewable materials are on the rise. Labels are being printed on post-consumer recycled paper using non-toxic inks. Some wineries, like Fetzer, have even switched to biodiesel-powered trucks to deliver their wines.

Solomon Simon Jacob: 6:31

To ensure these efforts are more than marketing buzz, many wineries seek third-party certifications. In California, essip-certified Sustainability in Practice assesses everything from pesticide reduction to water efficiency to community outreach. In Oregon and Washington, live Certified holds vineyards to rigorous environmental and social standards. The California Sustainable Wine Growing Alliance, cswa, offers an overarching framework with over 200 criteria, proudly publishing their compliance metrics annually. In short, sustainability in wine is not a single act, it's a mindset. It's about stewardship, transparency and accountability. It asks can we grow better wine and be better neighbors to the land and people? Let's shift from sustainability to something even more holistic biodynamic winemaking. If sustainability is rooted in science and stewardship.

Solomon Simon Jacob: 7:41

Biodynamics adds a layer of spiritual ecology, a philosophy that sees farming not just as environmental management but as a form of cosmic harmony. Biodynamics was developed in the 1920s by Austrian philosopher and scientist, rudolf Steiner, who believed that modern industrial farming was depleting the vitality of both the land and the food it produced. In a series of lectures given to European farmers, he laid out a new approach to agriculture, one that treated farms as self-sustaining living organisms, integrated with the rhythms of the earth, moon and stars. Applied to winemaking, biodynamic viticulture builds upon the principles of organic farming no synthetic fertilizers, no chemical pesticides. At its heart is the belief that everything in the vineyard is interconnected the vines, the soil, the insects, the people, the animals and even the cosmos. Insects, the people, the animals and even the cosmos. Biodynamic farmers follow an astronomical planting calendar which divides days into four types fruit, flower, leaf and root days, based on lunar cycles and planetary alignments. For example, grape harvesting is often timed for fruit days, believed to best preserve flavor and vitality, while pruning may be done on leaf or root days to support balanced growth.

Solomon Simon Jacob: 9:18

One of the most distinctive aspects of biodynamics is the use of specially prepared composted treatments, known as preparations. These include cow manure that has been buried inside a cow horn over winter, then unearthed and diluted with water, often dynamized by vigorous stirring, and sprayed over the soil. It's believed to stimulate microbial life and root development. Crushed quartz silica packed into a cow horn and buried through the summer, then sprayed over the vines to enhance light absorption and photosynthesis. Other preparations use herbs like yarrow, chamomile, dandelion, oak bark, valerian and horsetail, either composted or applied as teas or sprays. Each one is thought to bring balance to a specific part of the vine's health, whether encouraging flowering, boosting immunity or regulating growth. To the outsider it may sound strange, even mystical, but for practitioners the proof lies in the vitality of the vineyard and the balance of the wine.

Solomon Simon Jacob: 10:31

Winemakers often report that their vines become more resistant to disease, their soils more alive with microbial diversity and their wines more expressive, even from difficult vintages. Take Domaine Le Flavre in Burgundy, a historic estate that turned to biodynamics in the 1990s after facing disease and declining yields. Since the switch, their vines have rebounded and their wines have earned global acclaim for purity and finesse. Or Nicolas Joly of Clos de la Coulee de Ceron, perhaps the most vocal biodynamic evangelist in the wine world, whose small Loire estate produces wines revered for their complexity and individuality. In Bordeaux, chateau Ponté-Canet, a classified growth in Pauillac, fully converted to biodynamics under Alfred Tesseron. Using horses instead of tractors, cultivating biodiverse insect habitats and introducing dynamized water into their treatments, the transformation was dramatic. Vine health improved and wine critics began awarding higher scores with each vintage.

Solomon Simon Jacob: 11:50

Biodynamic farming is not limited to France. In Israel, a growing number of winemakers are exploring biodynamic practices to reconnect with ancient rhythms of agriculture. Some boutique producers in the Judean hills and upper Galilee have begun experimenting with moon cycle pruning and compost infusions, seeing it as a return to more mindful stewardship of the land. Certification for biodynamic practices is overseen by international organizations like Demeter and Biodiven. These certifications go well beyond organics. They require deep ecological planning, documentation and annual audits to ensure authenticity. Demeter-certified wines are still relatively rare, but they are growing in number as both consumers and winemakers seek more soulful, terroir-driven expressions.

Solomon Simon Jacob: 12:50

Biodynamic winemaking doesn't just produce wine. It cultivates a relationship Between farmer and vine, between soil and sky and between the natural and the transcendent. Whether or not you embrace every aspect of the philosophy, one thing is clear For many winemakers, the vineyard feels more alive, and so does the wine. Let's now look at how this plays out in the real world. In Bordeaux, france, pont-et-canet is a fifth-growth estate in Pauillac that produces a limited release of kosher wines. State in Pauillac that produces a limited release of kosher wines, it turned heads when it embraced biodynamics. In the early 2000s, alfred Tesseron made the bold move to replace tractors with horses, allowing gentler soil compaction and deeper root growth. They used dynamized water, water that's stirred in a vortex motion to enhance its energy. According to biodynamic philosophy, they prepare compost using cowhorns filled with silica buried for months underground. The result Vines that are more resilient, wines that critics say have gained finesse and vibrancy, and a vineyard that feels more alive.

Solomon Simon Jacob: 14:10

Next, in Spain, elvi Wines is a kosher certified winery known for its commitment to sustainable agriculture and respect for tradition. Working across regions like Rioja and Priorat, elvi has implemented dry farming, native yeasts and minimal intervention practices to emphasize terroir and reduce their environmental footprint. They avoid herbicides and synthetic inputs, instead focusing on soil regeneration and vineyard biodiversity. Elvie is also exploring biodynamic techniques, harvesting and racking based on the lunar calendar, blending tradition with innovation. Their wines are not only kosher but also expressive, elegant and increasingly aligned with ecological principles.

Solomon Simon Jacob: 15:04

Then, in Israel, the Reconati winery has adopted sustainability with a Mediterranean perspective. Facing water scarcity. They use drought-resistant rootstocks and native varieties like Marawi and Betuni, focusing on minimal intervention and smart irrigation in the vineyards and investment in local ecosystems to direct their approach to winemaking. Their wines express place with authenticity and the vineyard is a model of climate adaptation. Again in Israel, domaine du Castel, based in the Judean hills near Jerusalem, is a leading example of premium kosher winemaking with a sustainable focus, is a leading example of premium kosher winemaking with a sustainable focus. Founded in 1988, the winery has grown from a backyard operation into one of Israel's most respected producers. While not officially biodynamic, castell emphasizes harmony with the land, minimal intervention and environmentally conscious vineyard management. Their relocation in 2015 to a modern facility in Yad Hashmona allowed for even more efficient and sustainable production, allowing for the replacement of much of the electrical pumping-based transfers of product, using gravity to facilitate their transfer. Castel's wines, including the iconic Grand Vin and C Blanc de Castel, have earned global acclaim for their balance, elegance and sense of place.

Solomon Simon Jacob: 16:42

Why take this path? Why abandon convenience and scale in favor of horses, compost and lunar calendars? Let's start with the most pressing reality climate change. Grape growing is inherently sensitive to weather and climate Warmer temperatures, erratic rain patterns and extreme events like frost or heat waves can devastate harvests. Events like frost or heat waves can devastate harvests. By adopting sustainable or biodynamic practices, wineries gain more resilient vines, healthier root systems and greater biodiversity, all of which help vineyards better weather these growing uncertainties.

Solomon Simon Jacob: 17:23

Next is the health of the soil. After decades of conventional farming, many vineyard soils around the world have been depleted of life. By reintroducing compost, planting cover crops and minimizing synthetic inputs, winemakers can rebuild their soil's microbial life. Why does that matter? Because healthy soil isn't just dirt. It's the life source of the vineyard. It determines how vines feed, how grapes ripen and, ultimately, how the wine tastes. But it's not just about the environment. There's also an economic and philosophical dimension. Wineries that invest in these practices often reduce long-term costs, especially in water and chemical usage. They may also attract loyal customers willing to pay a premium for authenticity and ethical transparency. And then there's the matter of legacy.

Solomon Simon Jacob: 18:24

Many family-owned wineries view themselves as stewards, not just producers. They want to hand off the land to the next generation in better condition than they received it. Sustainability becomes a moral imperative, not just a marketing label For biodynamic producers. There's also a spiritual and energetic motivation. Some speak of creating harmony between the vineyard and the cosmos. They see winemaking not just as agriculture, but as art and healing. This may sound poetic, but to many who walk their vineyards and taste their wines, it also feels profoundly real. So whether it starts from a spreadsheet, a soil test or a sense of sacred duty, the motivations are deeply rooted. These winemakers aren't just growing grapes, they're cultivating a vision.

Solomon Simon Jacob: 19:21

Here are some quotes from winemakers about sustainability Elie Ben-Zaken, founder Domaine du Castel, israel. We don't just make wine, we take responsibility for the land. If we harm the soil, we harm the soul of our wine. Daniel Rogov, israeli wine critic, paraphrasing Castel's philosophy Castel understood early that great wine doesn't come from modern technology alone. It comes from care, from harmony between man and nature. Gar Eliraz, on Reconati Winery, israel. Our climate is changing fast. If we don't adapt by planting smarter, irrigating less and nurturing local varieties, we're not being responsible vintners, we're just renters on borrowed land.

Solomon Simon Jacob: 20:13

Some additional quotes on biodynamics Alfred Tesseron, pont-et-canet, france. Biodynamics is not magic, it's listening to the vineyard, to the animals, to the cosmos. When the vineyard is in balance, the wine finds its own voice. Elisabetta Foradori, italy, a Demeter-certified producer. Biodynamics gave me a language for something I already felt that wine is alive. It has rhythm, energy and memory. Victor Urrutia, ceo Sivini, spain. We don't inherit vineyards from our ancestors. We borrow them from our grandchildren. Gabriel Geller, wine industry expert.

Solomon Simon Jacob: 20:57

Kosher wine consumers are more conscious now. They don't just want kosher certification, they want meaning in their bottle ethics, ecology and excellence. Meaning in their bottle, ethics, ecology and excellence. Here are some quotes on Consumer Connection. Writer David Silverman on Elvie Wine, spain. We've always believed that kosher wine can be world-class Sustainability. Lets us tell a deeper story, not just about religion, but about the earth. Winemaker Nicolas Joly, owner of Clos de la Coulee de Serran, france.

Solomon Simon Jacob: 21:34

When you treat nature like a partner, not a machine, the wine becomes a messenger of place. You're not drinking a product, you're drinking a conversation. So what's in it for you, the wine lover? Let's begin with the most immediate and intimate aspect taste.

Solomon Simon Jacob: 21:54

Sustainable and biodynamic wines often offer a more authentic expression of their terroir. This is because vines growing in biologically rich, undisturbed soil develop deeper root systems, drawing up a broader range of nutrients and minerals. These nutrients influence not just the ripeness of the grapes, but their aromatic complexity, mouthfeel and balance. As a result, wines from healthy ecosystems frequently display heightened freshness, clarity and tension. Biodynamic wines, especially, are known for their elegance, lifted aromatics and a sense of vibrancy that many wine professionals describe as alive in the glass.

Solomon Simon Jacob: 22:40

Now consider the health implications. Sustainable and biodynamic producers avoid synthetic herbicides, pesticides and fertilizers, which not only protect the environment but also reduce chemical residue in the wine. These wines are often fermented with indigenous yeasts that come naturally from the vineyard and the winery, rather than laboratory-cultured strains. Native yeast fermentations are slower and more nuanced, allowing more complexity to develop. Lower sulfite levels are also common, making these wines gentler for those who are sulfite-sensitive. Additionally, sustainable wineries often employ less invasive fining and filtration processes. This means the wine retains more natural phenolic compounds, which some studies suggest may carry health benefits, like antioxidants and polyphenols, when consumed in moderation. Many of these wines are also vegan, as they avoid animal-based clarifying agents, which are often found in non-kosher certified wines.

Solomon Simon Jacob: 23:52

Beyond physical health, let's look at mental and emotional well-being. Choosing wines that are ethically and environmentally sound offers a sense of satisfaction and purpose. You're not just buying a beverage, you're making a conscious choice. Supporting sustainable viticulture affirms your values environmental stewardship, respect for nature and social responsibility. Speaking of values, sustainable wines often come from producers who care deeply about transparency. Many publish their vineyard practices, soil care methods, water conservation efforts and social impact reports. This transparency builds trust. As a consumer, you know where your wine comes from, how it was made and who made it. That knowledge turns a bottle into a story and a story into a connection. These connections go further.

Solomon Simon Jacob: 24:53

Wines from small, sustainable or biodynamic wineries often reflect the fingerprints of their makers. They aren't industrial, mass-market products. They're expressions of people, places and philosophies, of people, places and philosophies. Drinking these wines invites you to experience a region's climate, traditions, struggles and aspirations. It's cultural immersion through a glass. There are even sensory and aesthetic benefits. Many natural and biodynamic wines use minimal packaging and avoid heavy bottle glass, reducing their carbon footprint. Labels often emphasize artistry, storytelling and local identity. You'll notice more corks from sustainable forests, less foil and recyclable materials. Lastly, there's the communal benefit. Lastly, there's the communal benefit. Sustainable wine culture often encourages education, hospitality and open dialogue.

Solomon Simon Jacob: 25:57

Visiting these wineries, should you get the chance, is usually a more personal experience. Tastings are often led by family members, winemakers or viticulturists themselves. This fosters a deeper appreciation of the craft and builds relationships between producers and consumers. So what's in it for you? Better taste, better health, better ethics, better transparency and a better story. You're supporting artisans, protecting ecosystems and enriching your experience with every sip.

Solomon Simon Jacob: 26:33

In a world filled with choices, sustainable and biodynamic wines invite you to choose mindfully and deliciously. So as you lift that next glass to your lips, I invite you to pause for a moment, not just to swirl, sniff and sip, but to reflect. Every bottle of wine has a story, and when it comes from a sustainable or biodynamic winery, that story often runs deep. Let's explore a few guiding questions to help you connect more meaningfully with the wine in your glass.

Solomon Simon Jacob: 27:10

How was this wine made? Was it crafted with care or churned out in a high-volume facility? Was the vineyard managed organically or chemically fertilized? Did the grapes ferment with native yeasts from the vineyard itself, or were they inoculated with lab strains designed for consistency? For example, wines from Elvi in Spain rely on minimal intervention and dry farming practices to let nature speak through the glass. Ponté Canet in Bordeaux ferments with indigenous yeasts and forgoes synthetic inputs altogether. Understanding how a wine was made helps you appreciate the craftsmanship or the lack of it behind what you're drinking.

Solomon Simon Jacob: 27:59

What choices did the winemaker make to preserve the land? Was water used wisely? Were cover crops planted to feed the soil? Did the winemaker use horses instead of tractors, like at Ponte Cane, to reduce soil compaction or employ gravity-fed systems to reduce energy use. In Israel, reconati has embraced drought-resistant rootstocks and native grape varieties like Marawi and Bituni, not just to honor heritage but to reduce environmental strain in an arid climate. Castel, nestled in the Judean hills, works with nature, not against it, to allow their vineyards to thrive for generations to come. Asking this question reminds us that a good wine should come from a healthy vineyard and that a healthy vineyard is a gift from intentional choices.

Solomon Simon Jacob: 28:58

Can I taste the place, the vintage, the care in the vineyard? This is the heart of terroir the idea that wine can reflect the soil, climate and culture of its origin. Can you taste the minerality from a limestone hillside, the sun-drenched ripeness from a particularly warm year, the tension between sweetness and acidity that tells the story of a cool climate harvest? In biodynamic wines especially, this sense of place often shines. It's not masked by additives or technology. Think of a Syrah from the northern Rhone with cracked pepper and violets that echo the granite soil and cool breeze. Or a Merawi from Israel that offers citrus and herbs, capturing the Mediterranean breeze and ancient soil beneath its vines.

Solomon Simon Jacob: 29:55

When wine is made with care, you're not just tasting grape juice. You're tasting geography, geology and even history. Does this wine connect me to something bigger than myself? This may be the most personal question. When you drink a wine that's been grown with intention by people who respect the earth, the workers and the process, it often carries a kind of resonance. Maybe it reminds you of a trip you once took or introduces you to a corner of the world you've never seen. Maybe it sparks a conversation around your dinner table. Maybe it gives you a sense of rootedness or mindfulness.

Solomon Simon Jacob: 30:40

In a fast-paced world, a sustainable or biodynamic wine by its very nature is part of a larger dialogue about climate, culture, ethics and community. When you drink with that awareness, wine becomes more than a beverage. It becomes a bridge. So next time you open a bottle, don't just ask do I like this? Ask, what am I really experiencing here? The answer might surprise you or even inspire you. Thank you for joining me on this journey into the heart of winery sustainability and biodynamics.

Solomon Simon Jacob: 31:19

Whether you're sipping a bold, age-worthy Bordeaux or a crisp, mineral-driven white from the hills of Israel, I hope today's episode has added a new layer of understanding, and maybe even a bit of wonder, to what's in your glass, because wine is never just wine. It's a story. It's a reflection of the soil, the season, the hands that tended the vines and the values that shaped every decision from bud to bottle. When that process is rooted in respect for the earth and care for the people involved, the result is more than just delicious it's meaningful. If today's conversation inspired you, if it sparked a question, a new curiosity or simply made you appreciate that bottle on your table a little more, share it with a friend. Tell someone who loves wine, nature or meaningful stories to tune in.
