Natural wine is best understood not as a single legally defined category, but as a loose movement of winemakers who intervene as little as possible between vineyard and glass. The label itself has no uniform, official definition—encyclopedic and industry sources agree on that point—but in practice it usually means grapes farmed without pesticides or herbicides, spontaneous fermentation with ambient yeasts, few or no additives beyond a small dose of sulfur dioxide, and little to no filtration or fining. If you've heard the words "funky," "cloudy," or "alive" used about wine and wondered what's going on, this is the guide.

What Defines Natural Wine?

Start with the simplest definition, offered by the importer Jenny and Francois Selections: natural wines are "wines made with the least possible use of chemicals, additives and overly technological procedures." That framing—least possible, not zero—is important, and it captures the spirit of the whole movement. Natural winemaking is a philosophy of restraint applied at every stage, from the soil the grapes grow in to the moment the cork goes in.

The absence of a uniform definition is the movement's signature quirk and its biggest controversy. As the Wikipedia entry on the subject puts it, natural wine "refers to a generalized movement among winemakers for production of wine using simple or traditional methods," and although there is no single definition, the wine is "usually produced using grapes that are farmed without the use of pesticides or herbicides, with no additives other than limited to no SO2 (sulfur dioxide), and limited to no filtration and fining." That word "usually" is doing honest work: these are norms, not rules, and individual producers interpret them differently.

It's worth pausing here, because the labels in the wine shop do not mean what you might assume. Natural wine is not the same thing as organic wine or biodynamic wine, even though the practices overlap heavily. Organic certification, as the Wine & Spirit Education Trust explains, is a set of formal requirements that vary by certification body but generally avoid synthetic herbicides, fungicides and pesticides in favor of gentler inputs like manure fertilizers, crop rotation, and cover crops for soil health—with copper sulphate permitted in small doses. Organic is a farming standard; it says nothing about what happens in the cellar. Natural wine, by contrast, is an unregulated whole-chain approach: farming choices and cellar choices together.

In the vineyard, natural wine producers typically farm organically or biodynamically, often working with older vines and harvesting by hand. Again, that's the general pattern rather than a universal rule. The through-line is trust in raw material: if the grapes are healthy and the vineyard ecosystem is alive, the argument goes, the wine needs less rescuing later.
