In short: organic wine follows a certified EU regulation that prohibits pesticides and GMOs in the vineyard. Natural wine is a philosophical choice of the producer—no law yet regulates it—and aims to intervene as little as possible both in the vineyard and in the cellar. Biodynamic wine adds a holistic view of agriculture to biology, with practices linked to lunar rhythms and soil vitality. Three different approaches, often overlapping, almost always compatible.
Organic Wine: The Only Category with a Law Behind It
Let's start here because it's the only one of the three terms that has a legally defined meaning. Since 2012, European regulation 203/2012 establishes what you can and cannot do to label a bottle as "organic wine"—and it's not just about how you cultivate the grapes.
In the vineyard, the use of synthetic pesticides, herbicides, chemical fertilizers, and genetically modified organisms is prohibited. So far, nothing surprising. The novelty compared to the past is that organic now also regulates the cellar: lower limits for total sulfur dioxide (maximum 100 mg/l for reds, 150 mg/l for whites and rosés), prohibition of some invasive oenological practices such as partial dealcoholization and the addition of certain additives.
Every producer who wants to use the organic logo on the label must be certified by a third party—in Italy, the main ones are ICEA, Suolo e Salute, CCPB, Bioagricert. These bodies conduct inspections, soil analyses, and checks on cellar records. It's not a formality.
That said, organic does not automatically mean "better wine" or "wine without defects." It means that the producer has chosen an environmentally friendly cultivation method and has agreed to be controlled by someone. That's already a lot.

Natural Wine: A Philosophy, Not a Certification
Here things get complicated—and it must be said clearly. The term "natural wine" does not yet have a legal definition in Italy or in Europe. Anyone could technically write "natural wine" on a label without meeting any specific requirements. In practice, however, the market has self-regulated, and those who work seriously in this sector share a series of fairly solid principles.
A natural wine almost always starts from organic or biodynamic grapes (this is the shared minimum prerequisite). But the real difference is in the cellar: no added selected yeasts, only those indigenous ones naturally present on the skins; no acidity, color, or structure corrections; sulfur dioxide added to a minimum—often zero at harvest, something (very little) at bottling. Some associations like VinNatur or Renaissance des Appellations have formalized these criteria and organize internal fairs and controls, but these are voluntary memberships.
The result in the bottle can be surprising or disorienting, depending on expectations. These wines are often livelier, less predictable, with a certain natural turbidity and aromas that vary greatly from one vintage to another. They are not for all palates—and the most honest producers admit it.
What unites them is an idea: wine should express the place and the vintage, not the technological skill of the oenologist. A beautiful idea, which, however, requires impeccable raw material and very competent producers to really work.
Biodynamic Wine: When the Lunar Calendar Comes into Play
Biodynamic is often the most misunderstood of the three—by both enthusiastic supporters and hardened skeptics. It's worth trying to explain it without prejudice one way or another.
Biodynamic agriculture originated from the theories of Rudolf Steiner, an Austrian philosopher who gave a series of lectures on agriculture in 1924. The central idea is that the farm—or in this case the vineyard—is a self-sufficient living organism, in relation to cosmic rhythms. From this derive concrete practices: preparation 500 (manure fermented in a cow horn, diluted and dynamized in water and sprayed on the soil), the sowing calendar that distinguishes root, fruit, flower, and leaf days, and the total exclusion of chemical synthesis.
In the cellar, biodynamic principles largely overlap with those of natural wine: minimal intervention, indigenous yeasts, reduced sulfur dioxide. The most common certification is Demeter, recognizable by the logo on the bottle.
Does it really work? The honest answer is that enological science does not yet have definitive evidence on the effect of the lunar calendar on wine quality. What biodynamic producers do demonstrate quite clearly, however, is that their soils are more alive—richer in microbes, more permeable, more fertile—compared to comparable conventional vineyards. And living soils produce better grapes. Whether it's due to the cow horn or simply the obsessive attention these winemakers dedicate to the vineyard, the result is often felt in the glass.

Can they coexist? Yes, and often it's the norm
A producer can be simultaneously organic, biodynamic, and make natural wines. Indeed, this is the most common situation among the artisan winemakers we select: they start from organic certification as a minimum base, adopt biodynamic practices in the vineyard, and in the cellar, they work with minimal intervention in line with the natural philosophy.
The distinction is therefore not a scale of values—biodynamic is not "better" than organic, natural is not "purer" than everything else. They are different approaches with different histories, responding to different questions. The important thing, when choosing a bottle, is to know what you are buying and from whom it comes.

Frequently Asked Questions
Is organic wine healthier than conventional wine?
There is no definitive answer in terms of health, because wine contains alcohol regardless of the production method. What changes is the absence of synthetic pesticide residues and a lower amount of added sulfites. For those sensitive to sulfites, an organic or natural wine with reduced sulfur dioxide may be less problematic. For everything else, the impact on the body primarily depends on the quantity consumed.
How can I recognize an organic wine from its label?
Look for the green leaf logo of the European Union with the words "organic farming." It is legally mandatory on all certified organic wines sold in Europe. You will also find the code of the certifying body (e.g., IT-BIO-006 for ICEA). If there is only the word "organic" without the logo, it might be an unverified indication.
Are natural wines always cloudy?
Not necessarily, but many are. Turbidity in natural wines comes from the absence of aggressive filtration and the presence of residual yeasts in suspension. It is not a defect: it is a characteristic. Some producers choose to filter lightly to obtain a clearer wine without compromising its integrity. If turbidity worries you, gently shake the bottle before opening—it's not sediment to be removed.
What is the difference between vegan wine and organic wine?
They are two distinct things. Organic wine concerns the cultivation and winemaking method. Vegan wine concerns the fining agents used in the cellar: traditionally, fish glue, egg whites, or casein are used to make the wine clearer. A vegan wine uses plant-based alternatives or no fining agents. A wine can be organic but not vegan, and vice versa. Many natural wines are automatically vegan because they avoid any animal additives.
Does biodynamic wine cost more?
Generally yes, because biodynamic viticulture requires much more manual labor, lower yields per hectare, and the renunciation of any chemical emergency intervention. But the price difference is not always enormous: there are excellent biodynamic wines under 20 euros, as well as organic ones that cost much more. The price mainly depends on the denomination, the vintage, and the producer's reputation.
