Natural wine is the most contested category in the wine world — defended with near-religious conviction by its proponents and dismissed with equal force by traditionalists. Here is what it actually is, stripped of the ideology.
The Definition Problem
Natural wine has no legal definition. The term is used loosely to describe wine made with minimal intervention — but “minimal” is undefined. The general characteristics that natural wine producers aim for: organic or biodynamic viticulture (no synthetic pesticides or herbicides in the vineyard), hand harvesting, native/wild yeasts (the yeasts present on the grape skins, rather than commercially cultured strains inoculated into the must), no (or very low) added sulphites (SO₂ — the preservative used in almost all conventional wine), no fining agents (proteins added to clarify the wine), no filtration. The result when done well: wines that are more expressive of place and vintage (terroir), with a broader flavour complexity than highly processed conventional wine. The result when done badly: wines that are unstable, oxidised, contaminated by unwanted bacteria, or simply flawed and unpleasant.
The Spectrum from Pet-Nat to Skin-Contact
Natural wine encompasses a wide spectrum. Pétillant naturel (pét-nat): a sparkling wine made by bottling the wine while fermentation is still ongoing — the CO₂ produced continues inside the bottle, creating gentle bubbles without the addition of a liqueur de tirage (as in Champagne method). Often cloudy, lower alcohol, slightly funky, approachable. Skin-contact wine (orange wine): white wine made with extended skin maceration (the grape skins stay in contact with the juice for days to weeks, as in red wine production). Results in an amber-orange colour and tannins, with oxidative, nutty, dried-fruit flavours unusual in conventional white wine. The style originated in Georgia (kvevri amber wine) and Slovenia/Friuli, now made worldwide. Méthode nature sparkling: similar to pét-nat but with full fermentation before bottling, then secondary fermentation in bottle without disgorgement — the lees (dead yeast cells) remain in the bottle, typically cloudy. Orange wine is currently the most commercially successful natural wine style in restaurants and wine bars.
How to Taste Natural Wine Without the Ideology
The practical approach: taste without preconceptions in either direction. Natural wine at its best is genuinely interesting and more complex than the equivalent price point in conventional wine. Natural wine at its worst is faulty (mouse taint — a rare but very unpleasant fault caused by certain lactic acid bacteria — is more common in natural wine; excessive volatile acidity is another). Ask the sommelier or wine shop whether the wine is stable and drinkable now versus one that needs to settle. Natural wines are often more sensitive to temperature: serve them slightly cooler than conventional wines and consider opening the bottle 15–30 minutes before serving. The natural wine bar has become a significant dining format in most European capitals — a list of natural wines by the glass, typically limited but carefully selected, paired with simple plates of natural ingredients. This is often one of the best-value dining experiences in cities like Paris, Barcelona, London, and Berlin.
