.5. Yeasts, Bacteria, & Microbial NutrientsAdded to ensure fermentation finishes smoothly and cleanly without "stuck" vats.Active Dry Yeast: Laboratory-isolated, commercial yeast cultures used to start standard alcoholic fermentation.Lactic Acid Bacteria: Specific bacterial strains (like Oenococcus oeni) injected to drive smooth malolactic fermentation.Diammonium Phosphate (DAP): Synthetic mineral salt fed to hungry yeast as pure nitrogen fuel.Ammonium Phosphate: A structural fermentation fertilizer.Yeast Cell Walls (Yeast Hulls): Dried, dead outer hulls of yeast used to absorb toxic fatty acids and rescue stuck fermentations.Thiamine Hydrochloride (Vitamin B1): A growth nutrient stimulant added to maximize yeast health.Soy Flour: Highly specific yeast nutrient compound permitted under tight restrictions during active fermentation.6. Industrial Enzymes (Catalysts)Biochemical additives used to break down fruit matrices, speed up juice extraction, or filter stubborn sediment.Pectolytic Enzymes (Pectinase): Breaks down slick fruit pectins to maximize juice yields and ease clarity.Beta-Glucanase: Used to clarify wines made from botrytis-infected ("noble rot") grapes.Cellulase: Breaks down tough plant cell walls to speed up processing times.Catalase: Used to eliminate hydrogen peroxide residues from specific processing methods.Glucose Oxidase: An enzyme used to regulate oxygen exposure or alter internal sugar mechanics.Urease: Added to isolate and reduce urea levels, preventing the formation of ethyl carbamate (a carcinogen).
7. Concentrates, Sugars, & Flavor / Oak AdjustmentsIntroduced to radically alter visual density, disguise raw astringency, or mask missing barrel age.Concentrated Grape Must / Rectified Must: Highly sweet, unfermented syrup added to boost alcohol or inject residual sweetness.Mega Purple / Ultra Red: Dense Rubired grape concentrates added for thick color and sugar balancing.Saccharose (Cane Sugar): Pure sugar added to unfermented grapes (chaptalization) to achieve higher natural alcohol targets.Oak Chips, Shavings, & Oak Dust: Raw wood additives submerged into stainless steel tanks to simulate barrel-aging characteristics.Gum Arabic (Acacia Tree Sap): Added right before bottling to soften texture, reduce astringency, and prevent crystal drop-out.Ethyl Maltol: Highly regulated flavor compound used solely to mimic sweet fruit notes in alternative fruit wines.
8. Heavy Metal Eliminators & Specialty ChemicalsIntroduced to capture toxic chemical faults, metals, or severe visual flaws.Copper Sulfate: Poisonous in high amounts; used in tiny micro-doses to chemically bond with foul, stinky hydrogen sulfide (rotten egg smells).Ferrous Sulfate: Used in trace quantities to bind to and eliminate problematic excess iron or specific copper faults.Ferrocyanide Compounds (Blue Fining): Extremely regulated toxic process using potassium ferrocyanide to drop out severe heavy iron or copper contamination from white wines.Metatartaric Acid: Added to temporarily coat and prevent tartrate crystals from growing and falling out in the bottle.Potassium Bitartrate (Cream of Tartar): Added to tanks to force stable, controlled cold crystallization before bottling.Plant-Origin Proteins: Modern vegan protein isolates (derived from peas or potatoes) authorized as emerging alternatives to animal fining.Chitosan: A derivative used to clear cloudy wines or control spoilage yeast populations.
9. Atmospheric Gases, Water, & DiluentsUsed to manage pressure, structure volume, or prevent oxygen spoilage.Water (H₂O): Legally permitted to dilute overly thick grape sugars or adjust accidental volume levels under strict limitations.Carbon Dioxide (CO₂): Injected to create frizzante styles, retain structural freshness, or preserve still wines.Nitrogen (N₂): An inert gas used to blow out oxygen and blanketing tanks from spoiling.Oxygen (O₂): Injected via micro-oxygenation to soften aggressive tannins and replicate slow barrel aging.Acetaldehyde: Used in highly specific production streams to stabilize deep red pigments.Granular Cork: Authorized for use as a physical processing medium during specific cellar treatments.Distilled Alcohol: Neutral grape spirits used to arrest fermentation and stabilize high-alcohol fortified styles (like Port or Sherry).
The Unofficial "Natural Wine" Ban List While a commercial winery in the US can use all 70+ FDA-approved additives, a strict natural winemaker outlaws almost all of them:
Banned: Industrial Yeasts. Natural winemakers outlaw commercial, lab-grown yeast cultures. Fermentation must rely exclusively on native (ambient) yeasts already living on the grape skins and inside the winery.
Banned: Acidity and Sugar Adjusters. Adding tartaric acid to sharpen wine or adding cane sugar/concentrates (Mega Purple) to increase sweetness and body is completely forbidden.
Banned: Structural Tweaks. Artificial wood flavor enhancers like oak chips, oak dust, or chemical texture modifiers like gum arabic are outlawed.Banned: Heavy Fining and Filtration. Fining agents (animal proteins like gelatin and isinglass) and heavy mineral clays (bentonite) are banned. Natural wines are left un-fined and unfiltered, which is why they often look hazy or cloudy in the glass.
Banned: Heavy Preservatives. Chemical sterilizers like Velcorin and artificial stabilizers like potassium sorbate are strictly prohibited.
The Great Exception: Sulfur Dioxide (SO₂)The only additive that causes intense debate within the natural wine community is sulfur dioxide (sulfites).Zero-Zero Wine:
The strictest tier of natural wine. Absolutely zero sulfites are added at any point during production or bottling.
Minimal Intervention: Most natural winemakers allow a tiny dose of sulfites (usually under 30–40 parts per million) right at bottling to stabilize the wine for international shipping. For comparison, conventional wine laws permit up to 350 ppm of sulfites.
Certification Standards: France Leads the Way Because the term "Natural Wine" is highly prone to greenwashing, France became the first country to officially codify and legally recognize the movement under the designation "Vin Méthode Nature".To legally carry this logo on a bottle, a winemaker must pass strict criteria:Production Phase"Vin Méthode Nature" Legal RequirementVineyard Management100% Certified Organic grapes, picked entirely by hand.Yeast & FermentationOnly indigenous, wild yeast strains allowed.
AdditivesTotal ban on all processing aids, enzymes, sugars, and acids.Physical ManipulationBanned:
Reverse osmosis, spinning cones, flash-pasteurization.Sulfur Levels<30 mg/L total sulfites allowed across all wine styles.
Because the phrase "natural wine" or "low-intervention" cannot legally be printed on most wine labels, finding true low-intervention imports requires reading between the lines. You must look for official organic certifications, specific legal formatting, and verified importer names.Here is how to decode an imported wine label to find authentic, low-intervention bottles.
