What Is Vegan Wine?

Vegan wine is wine made without the use of animal-derived substances at any stage of production. Grapes are, of course, plants—yet certain traditional winemaking practices (especially fining and clarification) may employ animal products. Vegan wine avoids those inputs entirely, relying on either plant-based or mineral fining agents—or simply allowing time and gravity to clarify the wine naturally.

Vegan status focuses on inputs, not necessarily on farming style. A wine can be vegan and also natural, organic, or biodynamic, but these categories address different aspects of how wine is grown and made.

Why Some Wines Aren’t Vegan

After fermentation, winemakers often “polish” a wine’s appearance and texture through fining. Fining binds with compounds that contribute to haze or astringency, allowing them to precipitate out. Historically, several effective fining agents have been animal-derived, which makes the finished wine non-vegan even if no animal product remains in the bottle at measurable levels.

Fining Agents: Animal-Derived vs. Vegan Alternatives

• Egg white (albumin) — Source: eggs — Vegan? No — Purpose: softens tannins in red wines.
• Isinglass — Source: fish bladder — Vegan? No — Purpose: clarification, especially in whites.
• Casein — Source: milk protein — Vegan? No — Purpose: removes browning/oxidation tones in whites.
• Gelatin — Source: animal collagen — Vegan? No — Purpose: clarifies; reduces bitterness/astringency.
• Bentonite — Source: mineral clay — Vegan? Yes — Purpose: removes proteins/haze; common in whites/rosés.
• Activated charcoal — Source: mineral/plant — Vegan? Yes — Purpose: color/odor adjustments (used sparingly).
• PVPP — Source: synthetic polymer — Vegan? Yes — Purpose: removes browning phenolics/bitterness.
• Silica sol — Source: silicon dioxide — Vegan? Yes — Purpose: protein stabilization (often paired with other agents).
• Pea protein / potato protein — Source: plant-based — Vegan? Yes — Purpose: astringency reduction; clarification.

Many low-intervention producers skip fining altogether and rely on settling, racking, and time. These wines may appear slightly hazy—which is normal—and are often both vegan and aligned with natural wine practices.

Beyond Fining: Hidden Non-Vegan Touchpoints

Fining is the most common reason a wine isn’t vegan, but there are other places where animal products can sneak in:

• Beeswax on corks: Occasionally used as a sealant; check producer notes if strict veganism is required.
• Casein-based glues/labels: Rare in modern production, but still worth noting for strict standards.
• Clarification aids upstream: Even juice transport or filtration media can raise questions—transparent producers will disclose details.

If you need certainty, look for explicit “Vegan” labeling, third-party certification, or shop curated assortments like our vegan wine collection.

Vegan vs. Natural, Organic & Biodynamic

These categories overlap but focus on different checkpoints:

• Vegan: No animal-derived inputs (fining, processing aids, packaging touches).
• Organic: Prohibits synthetic pesticides/herbicides in the vineyard; cellar rules vary by region.
• Biodynamic: Holistic agro-ecology with composts, cover crops, and lunar rhythms; often minimal-intervention in the cellar.
• Natural wine: A cellar-first philosophy—native yeasts, low/no additives, unfined/unfiltered—often vegan, but not by definition.

In practice, you’ll find many wines that are both vegan and natural/organic/biodynamic. Producer transparency and store curation (like ours) make it easier to shop according to your values.

How to Tell If a Wine Is Vegan

• Labeling: Look for a clear “Vegan” statement or icon on the back label.
• Producer tech sheets: These often identify fining agents or clarify “unfined/unfiltered.”
• Retailer filters: Use our vegan wine filter to browse with confidence.

Certifications & Labels

Several organizations certify vegan products, and some wineries use these marks on labels and websites:

• The Vegan Society (UK): The well-known “Vegan” sunflower mark.
• BeVeg: Global vegan certification program for food and beverages.
• V-Label (EU): Recognized vegetarian/vegan labeling scheme with audits.

Not all producers pursue certification; many are vegan by practice and communicate this via tech sheets or retailer notes.

Vegan Wine FAQ

Is unfiltered wine always vegan?

Not necessarily—unfiltered wines often are vegan, but unfiltered does not guarantee vegan status. Check for animal-free inputs and producer confirmation.

Are sulfites compatible with vegan wine?

Yes. Sulfites are not animal-derived. A wine may contain sulfites and still be vegan. If you prefer low/no added SO₂, use filters in our natural wine selection or read the product notes.

Does vegan certification change the taste?

Certification itself doesn’t change flavor; it verifies inputs. Taste is driven by grape variety, terroir, and cellar choices (fermentation vessels, aging, etc.).

Are all natural wines vegan?

Many are, but not all. Natural wine focuses on low-additive, native-yeast approaches; vegan wine specifically excludes animal-derived inputs. Look for both attributes in the product details if important to you.
