“Wine used to be about joy. Now it’s a battlefield between monks and mad scientists.”

Welcome to the great divide. On one side, barefoot winemakers preaching purity. On the other side, lab-coated technicians armed with enzymes and spreadsheets.

The difference between natural wine and conventional wine goes beyond ingredients. It's about unique production methods, flavour profiles, and environmental impact. This article will explore what sets them apart.

Natural vs. conventional wine isn’t just about what’s in your glass. It’s a referendum on how we want to interact with nature, health, risk, control, and flavour.

Let’s break it down: with truth, clarity, and a little irreverence.

What Is Wine, Really? The Production Basics

At its core, wine is fermented grape juice. Everything else, yeasts, enzymes, sulphites, marketing spin, is a choice.

  • Fermentation
    • Natural Wine: Wild yeasts (ambient, from vineyard/cellar)
    • Conventional Wine: Cultured yeasts (selected for reliability; include genetically modified strains to achieve specific flavours)
  • Additives
    • Natural Wine: Minimal (if any)
    • Conventional Wine: Hundreds allowed: acids, tannins, enzymes, colour
  • Sulfites
    • Natural Wine: Low or none added
    • Conventional Wine: Frequently added pre- and post-fermentation
  • Filtration
    • Natural Wine: Minimal, rare or avoided
    • Conventional Wine: Common for clarity and shelf stability
  • Farming philosophy
    • Natural Wine: Organic / Biodynamic / Minimal intervention
    • Conventional Wine: Industrial / Integrated / Conventional
  • Batch size
    • Natural Wine: Small, artisanal
    • Conventional Wine: Large-scale, commercial, mass produced like a batch of your favourite sugary pop.

After reviewing the table, it's clear that natural wines differ significantly from conventional wines in every way from fermentation methods to the use of additives.

Natural Winemaking: Faith in Ferment

Most of not all natural winemakers believe that great wines are produced in the vineyard, not the cellar. You let the vineyard speak. You take your hands off the wheel. And most of the time, it works, unless at the hands of an inexperienced winemaker.

  • Wild fermentation gives natural wines unpredictability and a layer of authenticity you can’t fake. Wild yeasts found on grape skins are essential for natural fermentation.
  • No added enzymes, colourants, or sugar tweaks means you taste what the vintage gave you, with minimal human intervention in the fermentation process.
  • Low-sulphur approaches help preserve microbial life but may shorten shelf life or introduce instability. Hence, while natural winemakers strive for minimal added sulphites, they add anywhere between 30 and 700PPM.
  • Unfiltered and unfined means texture, cloudiness, and sediment—all signs of “nothing added, nothing taken away.”

Natural wine production is much more labour-intensive and often results in smaller batch sizes, reflecting the hands-on care and attention required for each bottle.

This is wine as art, not as algorithm. It’s also riskier, and not every bottle survives the process. But for natural wine lovers, the flaws are part of the beauty. A little VA? A little brett? It’s soul. The winemaker chooses to step back, allowing nature to take its course with minimal intervention.

The final wine is a pure expression of the grapes and the vintage, free from unnecessary additives.

Conventional Winemaking: Control Freaks Anonymous

Conventional winemaking doesn’t trust chance. It optimizes for stability, shelf life, and mass enjoyment. Conventional wineries often use irrigation systems in their vineyards to ensure reliable grape yields, regardless of weather conditions.

  • Yeasts are selected for predictability. The fermentation starts fast and finishes dry.
  • Additives help adjust acid, tannin, texture, colour, and aroma. Colouring agents are also used to achieve a consistent appearance across vintages.
  • Fining and filtration polish the wine, removing proteins, microbes, and particulates.
  • Sulphites stabilize and preserve—especially important for global shipping and aging.
  • Temperature control is used during fermentation to ensure consistent results and a clean, stable product.

Is it manipulation? Yes. Is it inherently evil? No. If your goal is consistency, scalability, and commercial success, conventional wineries are how you get there. This is the reason why conventional wines are often referred to as designer wines. A brand holds a focus group to determine the optimal taste profile and then mass produces a wine to match that profile. Artistry? Definitely not! Science? Definitely yes!

What Makes a Wine, Wine? The Key Characteristics

What separates a glass of natural wine from its conventional cousin? It all comes down to the winemaking process and the philosophy behind it. Natural wine producers are champions of minimal intervention. They let the fermentation process unfold with wild yeasts, skip the synthetic pesticides, and avoid the laundry list of additives that define regular wine production. The result? Natural wines are typically unfiltered, often a little hazy, and may contain only minimal added sulphites, if any at all.

This hands-off approach ensures that the final product is a true reflection of its unique terroir and the organic practices employed in the vineyard. Wine enthusiasts who crave authenticity love that each bottle tells a story of nature, not chemistry. Unlike conventional wines, which rely on controlled fermentation, synthetic fertilizers, and additives to ensure consistency and shelf stability, natural wines embrace the unpredictable. Flavours can shift from bottle to bottle, vintage to vintage.

Key characteristics of natural wines include a focus on sustainable practices, the use of wild yeasts, and a commitment to letting nature take the lead. For wine lovers, understanding these differences is essential: natural wine isn’t just a drink, it’s an experience shaped by the land, the weather, and the winemaker’s decision to step back and let the grapes do the talking.

Flashpoint: The Wine Civil War

The most iconic wine feud isn’t over tannins or terroir. It’s over ideology.

  • Naturalists
    • Heroes: Alice Feiring, Isabelle Legeron
    • Philosophy: Wine should reflect nature, not winemakers
    • Criticisms: Dogmatic, unpredictable, sometimes flawed; the natural wine claim about liveliness and terroir-driven flavour is debated.
  • Conventionalists
    • Heroes: Robert Parker, Michel Rolland
    • Philosophy: Wine should be expressive, polished, and pleasurable
    • Criticisms: Manipulative, homogenous, terroir-erasing. No artistry. Just science. It is the equivalent of AI art.

This isn’t just a stylistic battle. It’s a culture war. Old world vs. new world. Artisan vs. industry. Chaos vs. control.

The “Flaw” Debate: Fault or Funk?

Let’s talk dirty—literally. Natural wines are notorious for what the industry labels as “flaws”: they often exhibit a more rustic and dynamic flavour profile compared to the smoother taste of conventional wines, which can make them polarizing but also uniquely expressive. Most natural wines are known for their freshness and unique sensory attributes, which can include cloudiness and a dynamic flavour profile.

  • Volatile Acidity
    • Natural Wine View: Adds lift and complexity
    • Conventional View: Spoilage indicator
  • Brettanomyces
    • Natural Wine View: Earthy, rustic charm
    • Conventional View: Hygiene failure
  • Mouse (mousiness)
    • Natural Wine View: A rare textural quirk
    • Conventional View: Undrinkable off-flavor
  • Cloudiness
    • Natural Wine View: Authentic and raw
    • Conventional View: Unprofessional

Flaws sell. In a world of polished sameness, some consumers crave edge and imperfection. It’s punk rock winemaking.

Key Insight: Many of the world’s finest wines are produced naturally and biodynamically. However, the wine world is also plagued by many inexperienced winemakers who attempt to make wine, often labelling their unsuccessful efforts as 'natural'. When in doubt, always opt for an established wine brand.

Organic and Biodynamic: The Farming Foundation

Natural wine is almost always rooted in organic or biodynamic farming. But don’t confuse the two. Natural wine production prohibits synthetic fertilizers and chemical insecticides, ensuring a closer connection to the environment and the vineyard’s natural ecosystem. While many producers follow organic practices, only those who meet specific standards and undergo inspection can label their products as certified organic—a formal acknowledgment by regulatory bodies.

  • Organic_ No synthetic pesticides, herbicides, or fertilizers
  • Biodynamic: Uses cosmic calendars, compost preps, and treats the vineyard as an organism

Organic wines are produced without synthetic chemicals and must adhere to specific regulations, including limits on additives like sulphites. Biodynamic farming is essentially a blend of agriculture and astrology, yet it produces some of the world’s most iconic wines (see: Domaine de la Romanée-Conti, Nikolaihof, Coulée de Serrant).

What matters: These approaches prioritize soil health, microbial diversity, and resilience, which many believe translate into more expressive wines.

What’s Actually in Your Wine? The Additives Scorecard

The average wine label hides a chemistry lab. There are up to 200 ingredients. Here’s a glimpse of the most common ones:

  • Sulphur Dioxide (SO₂): Acts as an antioxidant and microbial stabilizer
  • Mega Purple: Concentrates colour and sweetness in red wine
  • Tartaric Acid: Balances low-acid grapes
  • Copper Sulfate: Removes off-odours, especially hydrogen sulphide
  • Isinglass, Casein: Used as fining agents (some are animal-derived)
  • Glycerol, Sorbitol: Adds smoothness and sweetness
  • Coloring agents: Enhance or adjust the wine colour, commonly used in conventional wines

Natural wines avoid these by default. That’s not always better—but it is more transparent.

While some natural and organic wines are marketed as sulfite free, most actually contain naturally occurring sulphites. The key distinction is that sulphite-free wines do not have added sulphites, unlike many conventional wines.

Handcrafted or Hard Labour? The Human Cost of Natural Wine

Behind every bottle of natural wine is a story of sweat, soil, and serious dedication. Natural winemaking is famously labour-intensive—think hand-tending vines, manual harvesting, and meticulous sorting, all done without the shortcuts of synthetic fertilizers or industrial chemicals. Natural winemakers are out in the vineyards, rain or shine, nurturing their grapes with organic methods and a holistic approach that prioritizes the environment.

This commitment to sustainable practices doesn’t just benefit the land; it also means healthier soils and more resilient vines, which in turn create wines that truly express their terroir. But make no mistake: the human cost is real. Natural wine production requires long hours, physical effort, and a willingness to accept the risks associated with minimal intervention. There’s no safety net of additives or high-tech fixes—just the winemaker’s skill and nature’s whims.

For many natural wine producers, this hard work is a labour of love. They’re driven by a passion to create authentic wines that reflect the world around them. And for consumers, choosing natural wine is more than a taste preference—it’s a way to support sustainable practices and fair labour in the wine industry, one glass at a time.

Is Natural Wine More Sustainable?

Yes. Usually. But not always. Let’s unpack that.

  • Small producers mean lower emissions per batch, but less scale efficiency.
  • No irrigation or chemicals can be better for long-term soil health.
  • Bottling and shipping are still environmental concerns (natural or not). Many wineries are now utilizing lightweight bottles and alternative packaging to minimize transportation emissions and reduce their overall environmental impact.
  • Shelf stability can be worse, leading to more spoilage and waste.
  • Climate change is prompting the wine industry to adopt more sustainable practices, as shifting weather patterns disrupt grape growth and challenge traditional viticulture methods.

Bottom line: natural wine prioritizes sustainability as a core value, with each winery playing a key role in implementing eco-friendly practices, whereas conventional wine treats it as an optimization problem. Different philosophies. Same goal: survive the climate crisis.

Natural Wine and Your Health: Miracle or Myth?

Is natural wine the secret to a healthier life, or just another wellness myth swirling in your glass?

Natural wines tend to contain significantly fewer synthetic chemicals and additives than conventional wines, with 5 to 10 times lower levels of sulphites and no artificial preservatives. While the conventional lobby argues that natural wines lack scientific proof of their health benefits, you decide whether no chemicals or very few chemicals are better for your health.

Some studies suggest that natural wines may offer higher levels of antioxidants and polyphenols—compounds linked to heart health and other benefits. But let’s not forget: wine is still an alcoholic beverage, and overindulgence can outweigh any potential perks, no matter how “natural” the bottle claims to be.

For most consumers, the real draw of natural wine is taste, transparency, and a commitment to sustainable practices. If you’re looking for a more natural product with fewer additives, natural wine is a solid choice. Just remember, moderation is key, and the best wine for your health is the one you enjoy responsibly, as part of a balanced lifestyle.

Final Thougths

The Takeaway: This Isn’t a Trend. It’s a Rebellion.

Natural wine isn’t going away. It’s not a fad. It’s a countercultural response to industrial sameness—a movement led by millennials and Gen Z who’d rather drink the story than just the product.

But don’t get it twisted. Natural wine isn’t inherently better. It’s just more honest about its tradeoffs.

"The wine world doesn’t need more rules. It needs more rebels with good taste and clean barrels."

Now go drink something weird—and make up your own mind.
