The Moon, the Vine, and a New Way of Making Wine: The Ancient Rhythms Modern Winemakers Are Rediscovering

For centuries, farmers and winemakers around the world have whispered about the moon’s influence on plants — but dismissed as folklore or superstition in the age of industrial agriculture.
Now, as land‑centric and regenerative farming movements rise, these once‑derided techniques are returning with scientific curiosity and real results.

At the heart of this revival is lunar farming and biodynamic agriculture — practices that treat nature not as a mechanical system to be controlled, but as a rhythm to be observed and worked with.

In this fascinating interview from our latest episode, a Swiss biodynamic winemaker talks to Karnvir Mundrey and describes how she has transformed her family vineyard using lunar cycles, indigenous yeasts, and ancient observation. The result? Healthier vines, deeper flavors, and wines that truly reflect their land and season.

🌱 Why the Moon Matters to Plants (and Winemakers)

We all learned in school that the moon influences ocean tides. But because plants are made mostly of water — just like our bodies — the moon also affects how sap and juices flow inside them.

Ancient traditions from India to Europe believed in an energy called soma — the idea that plants absorb lunar influence at night. Long before satellites or weather apps, farmers used the lunar calendar to decide when to plant, prune, harvest, or let the soil rest.

This practice faded as modern chemistry and technology took over farming — but today, biodynamic agriculture is bringing it back with renewed respect.

🍇 A Biodynamic Winemaker’s Rhythm With Nature

In the interview, a biodynamic winemaker from Switzerland — working a family vineyard that’s Demeter‑certified (a rigorous biodynamic standard) — explains how she coordinates vineyard work with the moon:

When the moon is waning (shrinking):
Energy moves downward into the roots, and sap flow slows. This is the best time to prune, so the plant keeps strength in its roots rather than losing vitality in trimming.
When the moon is waxing (growing):
Sap flows upward toward leaves, buds, and grapes. Work that supports growth and expansion fits better here.

This isn’t arbitrary. In biodynamic thinking, timing matters because it aligns actions with what the plant is already doing — rather than working against it.

🧪 Lunar Cycles and Wine Clarity

The moon also plays a role in the winery itself. During waning phases, when plant juices and microscopic activity move downward, the wine’s particles settle more clearly — making filtration easier and producing a cleaner, more stable wine.

In biodynamic winemaking:

Fermentation is wild — relying on indigenous yeasts from the grapes themselves rather than industrial strains.
Minimal filtration and additives preserve complexity, just like sourdough bread preserves depth compared to factory yeast bread.
Copper, sulfur, teas, and essential oils support plant health without leaving long‑lasting chemicals in the soil.

This approach treats the vineyard as a living system, not a factory.

🔥 It’s Not Superstition — It’s Observation

There’s a misconception that biodynamic farming is mystical or religious. In reality, it’s grounded in careful observation:

Plants send signals about what they need and when.
Seasonal rhythms influence growth, sap movement, and soil activity.
Different plants have different needs — for moisture, stability, or airflow.

For example:

Aromatic herbs develop best in dry conditions — when water is lower in the soil, their volatile oils concentrate.
Root vegetables favor energy downward toward soil.
Fruit and leaf growth align with upward energy phases.

This approach asks farmers to watch nature with intention — to see what science hasn’t yet fully explained but nature clearly demonstrates.

🍷 Traditional Wisdom Meets Modern Taste

The wine produced in biodynamic vineyards tastes different — richer, more complex, and reflective of place (or terroir, as sommeliers call it). That’s because it’s not engineered; it grows.

Just like sourdough relies on wild yeast, biodynamic wine relies on nature’s own processes.

And this isn’t fringe anymore. Biodynamic and organic winemakers increasingly attract adventurous drinkers and connoisseurs who appreciate wine that expresses life rather than chemistry.

🌍 Why This Matters Beyond Wine

This isn’t just a story about grapes. It points to a larger shift in agriculture and business:

We are rediscovering ancient knowledge with modern respect
Sustainability now includes timing, rhythm, and observation
Nature isn’t predictable — but it can be trusted when we learn its patterns

For entrepreneurs, growers, and curious thinkers alike, this perspective invites a deeper relationship with nature — one where listening can be as powerful as doing.
