What Is Natural Wine? Everything You Need to Know

Natural wine has gone from niche curiosity to one of the most talked-about movements in American wine culture. You'll find it on the menus of top restaurants in New York, Los Angeles, and Chicago — but walk into any wine shop and ask for a definition, and you'll get five different answers.

That's because natural wine isn't a legally defined category. It's a philosophy. And understanding what it means — and what it doesn't — is the first step to deciding whether it belongs in your glass.

What Exactly Is Natural Wine?

At its core, natural wine is made with minimal intervention in both the vineyard and the cellar. Grapes are farmed without synthetic pesticides, herbicides, or fertilizers. In the winery, little to nothing is added or removed. No commercial yeasts, no fining agents, no flavor additives.

The result is a wine that proponents say reflects its terroir more honestly than conventional bottles ever could. Critics argue it's an unregulated label that invites inconsistency. Both sides have a point.

Most natural winemakers follow these core principles:

• Organic or biodynamic farming (often certified, sometimes not)
• Hand harvesting to avoid machine damage to grapes
• Native or ambient yeast fermentation — no commercial yeasts added
• No or very low sulfite additions (below 40 mg/L at bottling)
• No fining or heavy filtration

Natural Wine vs. Organic Wine vs. Biodynamic Wine

These three terms get confused constantly. Here's how they actually differ:

Organic Wine

In the US, USDA Certified Organic wine means grapes were grown without synthetic chemicals — and no sulfites were added. A wine made from organic grapes but with added sulfites can only say "made with organic grapes" on the label. Organic certification covers the farming, not necessarily the winemaking process.

Biodynamic Wine

Biodynamic farming treats the vineyard as a self-sustaining ecosystem, following a planting calendar based on lunar cycles and using specific preparations to build soil health. Demeter USA is the only certifier for biodynamic farms and products in the United States. Biodynamic wine can still use sulfites in the cellar — it's stricter than organic on farming, but not necessarily on winemaking.

Natural Wine

Natural wine typically starts with organic or biodynamic farming but goes further in the cellar. It's the least regulated of the three — there's no official certification in the US — which is why the term gets stretched in all directions. Some producers are genuinely committed to the philosophy. Others use it as a marketing label.

The Sulfites Question

If you've heard someone say they drink natural wine because it doesn't give them headaches, the sulfite debate is where that claim lives.

Sulfur dioxide (SO₂) has been used in winemaking for centuries as a preservative and antioxidant. Conventional wines can contain up to 350 mg/L. Natural wines typically contain far less — or none at all. According to the Organic Materials Review Institute, wines labeled as certified organic must have no added sulfites, with naturally occurring levels kept below 10 ppm.

The science on sulfites and headaches is mixed. Most people can tolerate sulfites without issue. Those with sulfite sensitivity (usually linked to asthma) may react, but the "red wine headache" is more likely caused by histamines, tannins, or simply drinking too much. Still, lower-intervention wines do tend to have lower overall additive loads, which some drinkers find easier on their system.

What Does Natural Wine Taste Like?

This is where things get interesting. Without commercial yeasts to standardize fermentation and without heavy filtration, natural wines can be unpredictable — and that's either the point or the problem, depending on who you ask.

Common flavor profiles include:

• Funky or earthy notes — often described as barnyard, mushroom, or wet stone
• Lower alcohol — many natural producers pick earlier for freshness
• Higher acidity — lively and food-friendly
• Slight fizz — especially in pét-nat (pétillant naturel) styles
• Cloudy appearance — from minimal filtration; this is normal and not a flaw

At their best, natural wines are alive, expressive, and deeply tied to their place of origin. At their worst, they can be volatile, over-oxidized, or just off. The margin for error is narrower without the safety net of additives.

Where Is Natural Wine Made?

The movement took off in France — specifically in the Loire Valley, Beaujolais, and Alsace — with producers like Marcel Lapierre and Olivier Cousin becoming its early champions. Today, natural wine is made on every major wine continent.

In the US, the movement is strongest in California, Oregon, and New York's Finger Lakes region. Producers like Broc Cellars in Berkeley, Bow & Arrow in Portland, and Channing Daughters on Long Island have built serious reputations making honest, low-intervention wines that punch well above their weight.

Internationally, Georgia (the country, not the state) deserves special mention. Its 8,000-year-old tradition of fermenting wine in buried clay vessels called qvevri is considered by many to be the original natural wine method — so significant that UNESCO recognized it as Intangible Cultural Heritage in 2013. If you haven't tried a Georgian amber wine, it belongs on your list.

How to Find Good Natural Wine

Because the category is unregulated, the best way to find quality natural wine is to buy from trusted sources — wine shops with knowledgeable staff who vet their producers, not just anyone slapping a buzzword on a label.

A few practical tips:

• Look for importers with a known natural wine focus — Louis/Dressner, Zev Rovine, and Jenny & François are well-regarded in the US market
• Ask your local wine shop which producers they trust personally
• Start with orange wines or pét-nats if you want an easy entry point into the style
• Don't dismiss a wine because it looks cloudy or smells a little different on first pour — give it time in the glass

At Glaser Wine, we select natural and low-intervention bottles based on producer reputation and consistency, not just category marketing. You'll also find our regional wine guides helpful when you want to go deeper into where these grapes are grown. And if you're building a collection, our wine storage guide covers everything you need to keep low-sulfite bottles in peak condition.

One thing worth noting: the natural wine crowd tends to overlap with a broader lifestyle orientation toward transparency and low-intervention consumption — from what's in their food to what they drink or even the vapes they choose. The common thread is knowing what's actually in the product.

Is Natural Wine Worth It?

That depends on what you're looking for. If you want predictability and polish, a well-made conventional wine from a reliable producer will deliver every time. If you want something that tastes like a specific place made by a specific person in a specific year — and you're open to a little variation — natural wine is worth exploring seriously.

The movement has pushed the entire wine industry toward more transparency about additives and farming practices. Even if you never buy a bottle labeled "natural," the conversation it's started has made wine better across the board.

FAQs — Natural Wine Explained

Is natural wine actually healthier than regular wine?

Not necessarily. Natural wine typically contains fewer additives and lower sulfite levels, which some drinkers find easier to tolerate. However, alcohol content and caloric density are similar to conventional wine. There is no clinical evidence that natural wine is healthier in a meaningful medical sense.

Why does natural wine sometimes taste funky or sour?

Natural wines fermented with ambient yeasts and bottled without heavy filtration can develop earthy, funky, or sour notes that conventional wines don't have. This is often intentional and considered a feature of terroir expression. If a wine smells like vinegar rather than earthy complexity, that may indicate a flaw rather than a style choice.

Does natural wine need to be refrigerated?

Low-sulfite natural wines are more sensitive to temperature and oxidation than conventional bottles. It's a good idea to store them in a cool, dark place and consume them within a shorter window after purchase — typically within one to three years for most styles, unless the producer specifies otherwise.

What is pét-nat wine?

Pét-nat, short for pétillant naturel, is a sparkling wine made using the ancestral method — the wine is bottled before fermentation is complete, so the remaining CO₂ is trapped inside, creating natural bubbles. It's generally low in alcohol, slightly cloudy, and one of the easiest entry points into natural wine.

How can I tell if a wine is truly natural or just labeled that way?

Since "natural wine" has no legal definition in the US, the label alone doesn't guarantee anything. Look for wines from importers and retailers with a known commitment to vetting producers. Check whether the producer uses certified organic or biodynamic farming, and look for transparency about their cellar practices on the winery's website or back label.
