Natural, organic and biodynamic wine: what the words really mean
Three labels, often used as if they meant the same thing. They do not. This guide explains what each one covers in the vineyard and the winery, which are certified and what to expect when you pour a glass.
Three different ideas
Walk into a wine bar in Mumbai or Bengaluru and you will hear all three words, often in the same sentence. These words get mixed up because they share a direction: less intervention, fewer chemicals, more attention to the vineyard. But they have very different rules.
- Organic is a legally defined farming system with certification.
- Biodynamic is a stricter farming philosophy, also certified, through private bodies.
- Natural is a winemaking approach with no single legal definition in most countries.
Our guide to how wine is made covers the steps these approaches change.
Organic wine
Organic viticulture bans synthetic fertilisers, herbicides and most synthetic pesticides. Growers use compost, cover crops and approved treatments such as copper and sulphur against fungal disease.
The detail that confuses buyers is the difference between "made from organic grapes" and "organic wine". Some rules cover only the farming. Others, such as the EU organic wine rules, also limit what can be done in the cellar, including lower maximum levels of sulphur dioxide than conventional wine.
In India, organic produce is certified under the National Programme for Organic Production, with the India Organic logo. Export markets usually require certification to their own standards as well. Look for a certification mark and the certifier's name on the label. Our guide to reading a wine label covers where to find them.
Biodynamic wine
Biodynamic farming grew out of lectures given by Rudolf Steiner in 1924. It treats the farm as a single living system. Beyond organic rules, it uses specific preparations made from fermented manure, minerals and herbs, applied in small amounts. Many growers also time tasks such as pruning and harvesting by a planting calendar based on the moon.
Biodynamic growers also aim to keep animals, cover crops and compost on the farm, so the vineyard feeds itself rather than relying on bought inputs. Some of these practices have no clear scientific basis. Opinion is divided. What is less disputed is that biodynamic growers tend to pay very close attention to their vines and soils. That attention alone can improve fruit quality. Certification is private, most commonly through Demeter.
Natural wine
Natural wine is usually understood as organic or biodynamic grapes, fermented with wild yeast, with nothing added or removed. That means no added acid, no fining, little or no filtration and little or no added sulphur dioxide.
There is no single legal definition in most countries. France introduced a voluntary "Vin Méthode Nature" charter in 2020, which sets rules for producers who sign up. Elsewhere "natural" on a label means whatever the producer says it means.
Without SO2 and filtration, natural wines can be more variable. Some are vibrant and full of character. Some show faults such as mousiness, volatile acidity or refermentation in the bottle. Fans often accept a little cloudiness or funk as part of the style.
What to expect in the glass
- Organic and biodynamic wines can taste exactly like conventional wines of the same style. The difference is mostly in the vineyard.
- Natural wines often look hazier and taste more variable from bottle to bottle. They may smell yeasty, cidery or slightly funky.
- Orange and skin-contact wines are common in the natural wine world, though not all of them are natural.
Low-sulphur wines are more fragile. In a hot country this matters a lot. A natural wine that has spent weeks in a warm warehouse or a sunny shop window can arrive tired or faulty. Buy from sellers who store wine cool and drink it fresh. Our guide to Old World versus New World wine gives more context on where many of these producers work.
A practical way to choose
- Decide what matters to you: farming practice, low intervention in the cellar or simply the taste.
- Look for a certification mark if farming matters. "Natural" alone tells you little.
- Ask the seller how the wine was stored, especially for low-sulphur bottles.
- Taste with an open mind, but do not excuse a clear fault just because the label says natural.
Knowing what sulphur dioxide, filtration and fining actually do helps you judge these wines on their merits. That understanding starts with how a wine is made from grape to bottle.
Common questions
Is organic wine free of sulphites?
No. Organic wine may contain added sulphur dioxide, though rules such as the EU's set lower limits than for conventional wine. Fermentation also produces small amounts naturally.
Is natural wine a legal category?
Mostly not. France has a voluntary charter for natural wine, but in most countries the term has no legal definition.
Why do some natural wines look cloudy?
They are often unfined and unfiltered, so yeast and other particles remain in suspension.
