Organic, Biodynamic, Natural: How to Finally Tell Them Apart

At a restaurant or wine shop, the choice can quickly become overwhelming. Between the green AB logo, the Demeter label, mentions of “living wine” or “no sulphites added”… it is easy to get lost.

Does organic wine taste better? Is biodynamics just witchcraft? Is natural wine necessarily vinegar? At Le Petit Musée du Vin, we designed an entire journey to untangle fact from fiction. Here is the essential guide to shining in conversation — and above all, to choosing your bottle more wisely.

1. Organic Wine: “No Synthetic Chemistry”

This is the most well-known benchmark, recognisable by the European logo (the star-shaped green leaf). Simply put: an organic winemaker forbids themselves from using synthetic chemistry derived from petroleum.

• In the vineyard: This is the golden rule. No herbicides (chemical weed killers) or synthetic pesticides. To protect the vines against disease, natural products are used — copper, sulphur, and herbal teas.
• In the cellar: Contrary to popular belief, organic wine can contain sulphites (to stabilise the wine), but at lower doses than conventional wine.

The goal? Protect the environment and the consumer’s health while ensuring a harvest. Note, however, that yields are often lower and less consistent than in conventional viticulture.

2. Biodynamics: “Organic + the Stars”

Often confused with organic farming, biodynamics goes much further. It is a method born in 1924 under the influence of philosopher Rudolf Steiner. A biodynamic wine is necessarily organic, but it adds an almost philosophical dimension:

• The vine as a whole: It is considered a complex living organism, connected to the soil, the air, and… cosmic rhythms.
• The preparations: The winemaker does not use conventional fertilisers. Instead, they energise the soil with very specific preparations, like the famous “horn manure” (preparation 500) buried in winter, or silica to capture light.
• The lunar calendar: Work in the vineyard (pruning, harvesting, bottling) often follows the cycles of the moon and planets.

The result? Very low yields, but wines often praised for their purity, their “vibration,” and a very strong expression of terroir.

3. Natural Wine: “The Grape, Just the Grape”

This is the most “rock ‘n’ roll” of the three. Long without an official definition, it refers to wines made with as little intervention as possible. As our dedicated module puts it: “It’s a wine that doesn’t cheat.”

• Indigenous yeasts: The winemaker does not add commercially purchased yeasts. Instead, they let the natural yeasts present on the grape skin do the work. Riskier, but it produces unique flavours.
• Zero additives (or almost): No fining agents, no enzymes, no filtration.
• The sulphur question: This is the key difference. Natural wine contains little or no added sulphites.

The taste? These are vibrant wines, sometimes a little hazy (because unfiltered). They can surprise with explosive fruity aromas, but also sometimes with more farmyard or cider-like notes.

Which One to Choose? The Museum’s Conclusion

There is no single “best” wine in absolute terms — there is only the wine that matches your expectations and your values.

• Organic is a fundamental environmental guarantee.
• Biodynamics is a pursuit of excellence and harmony with living things.
• Natural is a sensory adventure for those who love raw fruit.

But let’s not forget what matters most: organic or conventional, every winemaker is above all trying to protect their vines and make a living from their work.
