What Is Grape Leather? Is It Durable, Permeable, Biodegradable?

Grape Leather is a sustainable and innovative material made from wine by-products (grape skins, seeds, and pomace), and it belongs to plant-based vegan leather.

The core advantage of Grape Leather lies in its sustainability and circular economy value. It not only effectively solves the problem of agricultural waste disposal, but also perfectly aligns with the concept of circular economy. Compared to traditional animal leather, it significantly reduces reliance on animal resources, has a more environmentally friendly production process, and reduces carbon emissions and pollution.

Grape Leather has waterproof, wear-resistant, and flexible properties, and is widely used in shoes, bags, and accessories.

This post will explore the definition and manufacturing process of Grape Leather, as well as its durability, breathability, and biodegradability.

 

What Is Grape Leather?

Grape Leather is an innovative and sustainable plant-based vegan leather made from the waste products generated during wine production (such as grape skins, seeds and stems). It is an environmentally friendly solution that upgrades agricultural waste into high-performance materials. The most well-known producer is the Italian company Vegea, which was founded in 2018.

Raw Material Source

The raw material for grape leather comes from the by-products of the wine industry – grape pomace. Every year, hundreds of millions of tons of such waste are produced globally, and the grape leather technology converts these wastes into high-value materials.

How to Make Grape Leather?

Grape leather is made from the grape waste produced during the wine-making process. It is mainly produced in two ways: industrialized production and small-scale home production. The former represents a mature business model that upgrades and reuses wine-making waste, while the latter is more inclined towards an exploratory approach for fun.

 

Industrial Production of Grape Leather

Step 1: Raw Material Collection and Preparation

The core task of this stage is to collect and process the wine waste to extract the effective components.

• Collection of waste: Collect the solid waste remaining after wine production from the winery, namely “grape pomace”, which mainly includes grape skins, pulp, seeds and stems.
• Drying treatment: The collected pomace needs to undergo drying treatment to remove moisture.
• Natural sun-drying method: Some producers may adopt a more traditional and time-consuming natural sun-drying method. For example, the French company Planet of the Grapes will dry the grape pomace in the sun for several weeks.
• Industrial drying method: Another method is to use industrial drying equipment, which can significantly shorten the preparation time.
• Grinding into powder: Grind the completely dried pomace into fine powder. At the same time, chemical analysis shows that the polyphenols, tannins, lignin and natural wax in the grape skins already have “cross-linking, strengthening and waterproofing” properties similar to traditional plant tanning agents.

 

Step 2: Mixing, Forming and Drying

This is the key step in converting grape waste into leather materials.

• Mixing the pulp: Combine the grape powder obtained in the first step with bio-based polymers (such as water-based polyurethane), vegetable oils, natural fibers (such as hemp), and natural plasticizers and other components to create a flowing liquid pulp.
• Coating and forming: Apply the mixed pulp evenly onto the base fabric (usually made of natural fibers) to form a sheet of a certain thickness.
• Secondary drying: Conduct a second drying process on the coated material to make it finally solidify and form.
• Post-processing: After drying, the material can be customized in terms of thickness, surface treatment, and texture to make it more similar to traditional leather in terms of performance and appearance. For example, Vegea Company uses this material to produce handbags, shoes, and even car interiors.

 

Example: The “Paste + Scaffold” Method (Vegea / Wineleather)

Step	What Happens	Details
Collect Raw Material	Gather grape waste from wineries	Skins, seeds, stems, pulp (marc) — all the leftovers after pressing
Grind into Paste	Mill everything into a fine slurry/paste	The grape solids are ground until you can’t see any original shape — it becomes a smooth paste
Add Binders & Color	Mix with plant-based oils + water-based polyurethane	This creates a plant-based composite. Color can be adjusted at this stage by changing the paste color
Coat on Textile Scaffold	Spread the paste onto a fabric base	The fabric acts as a skeleton/scaffold — just like synthetic leather manufacturing
Dry & Cure	Let it dry naturally or in controlled conditions	Results in a soft, suede-like material with leather-like texture
Finish	Surface treatment, embossing, etc.	Final product ready for cutting & sewing

 

Key Challenges in Production

Challenge	Solution Approach
Consistency	Winery waste varies by grape variety, season, and region; blending and standardization help
Durability	Balancing bio-content with necessary synthetic binders for performance
Scalability	Limited by seasonal wine production and geographic concentration of wineries
Cost	Small-batch production and R&D expenses keep prices higher than conventional materials

 

DIY Home Small-Batch Production: Proof-of-Concept Exploration

If you want to give it a try yourself, you can refer to the following simplified steps. However, it is more of a proof-of-concept, and the final product will have a difference in performance and durability compared to industrial products.

• Prepare raw materials: Collect some grape skins and grape seeds (the residue after juicing).
• Dry and grind: Wash the grape skins and seeds, then dry them in the sun or at a low temperature, and grind them into as fine a powder as possible.
• Mix and thicken: Mix the powder with a small amount of natural vegetable oil (such as olive oil) and water, and stir to form a uniform paste.
• Spread and dry: Spread the paste evenly on a smooth glass plate or plastic sheet, and leave it to dry in the open air for several days.
• Form and remove the mold: When it is completely dry and forms a film, carefully peel it off the plate to make a simple “grape leather”.

 

Is Grape Leather Durable?

Yes, the durability is excellent. Bags made of grape leather can generally be used for 5 to 8 years, and their performance is sufficient for daily use. However, compared to traditional animal leather, there is still a certain gap in long-term durability.

 

Key Performance Data

The third-party test data can more objectively reflect its performance:

• Tensile Strength: Approximately 3–10 MPa, close to the lower limit of natural leather.
• Abrasion Resistance: The dry-state test can reach more than 50,000 cycles, indicating that its surface is very wear-resistant.
• Flex Resistance: At room temperature, it can reach more than 100,000 cycles, demonstrating excellent resistance to bending.
• Tear Strength: Generally excellent.

 

Durability Scorecard

Property	Rating	Details
‌Abrasion Resistance‌	⭐⭐⭐⭐⭐	‌2× more abrasion-resistant‌ than regular vegan leather (PI/PU leather)
‌Tensile Strength‌	⭐⭐⭐⭐⭐	Rated 5/5 for structural strength
‌Tear Resistance‌	⭐⭐⭐⭐	Good, though slightly less than full-grain cowhide
‌Water Resistance‌	⭐⭐⭐⭐	Can be enhanced with protective coatings (water-based PU)
‌Flexibility / Softness‌	⭐⭐⭐⭐⭐	Feels almost identical to real leather — soft like suede
‌Longevity‌	⭐⭐⭐⭐	Stable properties, resists cracking better than most vegan leathers

 

What Affects Durability

Factor	Impact
Binder composition	Higher synthetic binder content (bio-PU) improves durability but reduces biodegradability
Coating quality	Protective top layers significantly extend lifespan
Material thickness	Thicker sheets resist tearing better
Manufacturing precision	Consistent density and even coating prevent weak points

 

The Durability Advantages of Grape Leather

• Surface wear resistance and tear resistance: High-end grape leather products have excellent wear resistance and tear resistance, capable of withstanding daily scratches and wear.
• Flexibility and resistance to folding: It has outstanding flexibility and is less prone to damage due to bending compared to traditional leather.
• Daily water resistance: It has good water resistance and can easily handle liquid splashes in daily life.
• Ultraviolet resistance and weather resistance: Some high-end products have ultraviolet resistance, and are less likely to fade or age due to sun exposure.

 

Why Is It So Durable?

Process	What It Does for Durability
‌Enzymatic tanning‌	Removes pectin & cellulose, leaving only strong fiber structures
‌Natural tanning agents‌	Increases softness AND durability simultaneously
‌Plant-based oils + water-based PU binder‌	Creates a flexible yet tough composite — like a natural resin matrix holding grape fibers together
‌Protective topcoat (optional)‌	Boosts water resistance & scratch resistance to near-animal-leather levels

 

Grape Leather vs. Other Leathers

Material	Abrasion Resistance	Water Resistance	Lifespan (avg use)
Full-grain cowhide	★★★★★	★★★★★	10–20 years
Cactus leather (Desserto)	★★★☆☆	★★★☆☆	3–5 years
Apple leather (Frumat)	★★★☆☆	★★☆☆☆	2–4 years
‌Grape leather (Vegea)‌	★★★★☆	★★★★☆	‌5–8 years‌
Regular PU vegan leather	★★☆☆☆	★★☆☆☆	1–3 years

 

Comparison with Other Leathers

Material	Durability	Best Use
Grape leather	Moderate	Fashion accessories, light footwear, upholstery
Coffee leather	Moderate	Similar applications
Piñatex	Moderate	Bags, shoes, small goods
Mushroom leather (Mylo)	Moderate-Good	Improving rapidly
High-quality animal leather	Excellent	Heavy-duty, long-term use
Synthetic PU/PVC	Moderate-Good	Consistent but less sustainable

 

Where It Shines (Real-World Use)

Application	Durability Verdict
‌Handbags‌ (e.g., Strathberry)	✅ Excellent — holds shape, resists scratches
‌Shoes‌ (e.g., Gucci sneaker collabs)	✅ Great — 2× abrasion resistance vs. regular vegan leather
‌Car interiors‌ (Tesla tested it)	✅ Very good — stable under temperature changes
‌Boxing gloves‌	✅ Perfect — needs high abrasion resistance
‌Furniture‌	✅ Good — resists wear from daily use

 

The Limitations of Grape Leather

• Long-term durability is inferior to that of traditional leather: Due to the lack of natural oils in animal leather, grape leather may be more prone to cracking over a period of several decades of use.
• Partially dependent on PU coating: To enhance durability, many commercial products add water-based polyurethane (PU) coatings, but this also affects its complete biodegradability.
• Relatively low mechanical strength: Academic research indicates that its tensile strength and stiffness are still lower than those of traditional cowhide, and it may not be advantageous in scenarios requiring extremely high structural strength.

 

Where It Has Limits

Weakness	Explanation
‌Not fully waterproof‌	Without a topcoat, prolonged water exposure can damage it (but a protective coating fixes this)
‌UV yellowing‌	Like all plant-based leathers, it can yellow over time under direct sunlight — though less than PU vegan leather
‌Sharp objects‌	Can be punctured more easily than thick cowhide (same as most vegan leathers)

 

Is Grape Leather Biodegradable?

Yes. Grape leather is biodegradable. It is worth noting that grape leather can sometimes completely biodegrade, but often it does not. The answer to whether grape leather is biodegradable or not is: it depends on its specific composition.

 

The Key Factor Affecting Biodegradability: PU Coating

Many commercial grape leather products add a water-based polyurethane (PU) coating to enhance their durability. Although this coating is more environmentally friendly than traditional solvent-based PU, it is still a type of plastic and will prevent the product from complete biodegradation.

 

It Depends on the Type

Type	Biodegradable?	Time to Decompose
‌Vegea / Pangaia‌ (with PUD binder)	❌ ‌Not fully‌	Partial — takes years
‌Oddbird / Wineleather‌ (100% natural)	✅ ‌Yes, 100%‌	‌~6 months‌ ✅

 

The “Not Fully” Camp — The PUD Problem

Ingredient	Problem
Grape waste (skins, seeds, stems)	✅ Biodegradable
Plant-based oils	✅ Biodegradable
‌Water-based PUD (polyurethane)‌	❌ ‌Not biodegradable‌

 

What Prevents Full Biodegradability

Component	Issue
Bio-based polyurethane (bio-PU)	Commonly used for durability and water resistance; degrades very slowly or not at all
Synthetic coatings	Protective finishes often contain petroleum-derived compounds
Dyes and additives	Chemical colorants and stabilizers may resist decomposition

 

The Spectrum of Biodegradability

Formulation	Biodegradability	Typical Use
100% bio-based (grape + natural binders only)	Biodegradable / compostable	Rare; niche or experimental products
Grape + mixed bio/synthetic binders	Partially biodegradable (organic component only)	Most current commercial products
Grape + conventional synthetic binders	Not biodegradable	Lower-end or mass-market items

 

Biodegradable vs. Bio-based

These terms are often confused:

Bio–based materials refer to those that are partially or mainly made from renewable biological sources, such as grape waste.

Biodegradability means that under appropriate conditions, microorganisms can break down the material into natural substances within a reasonable time.

A material can be bio-based, but it may not be biodegradable. For example, grape leather containing polyurethane may be partially made from grapes, but due to the presence of its synthetic components, it will still remain in the environment.

 

Is Grape Leather Permeable?

Yes, grape leather is generally regarded as a material with good breathability.

 

It Depends on the Type

Type	Air Permeability	Water Vapor Permeability	Feel
‌Natural binder‌ (Oddbird, Wineleather)	⭐⭐⭐⭐ Good	⭐⭐⭐⭐ Good	Suede-like, breathes well
‌PUD binder‌ (Vegea, Pangaia, Gucci)	⭐⭐⭐ Moderate	⭐⭐⭐ Moderate	Smooth, less breathable than suede
‌Regular PU vegan leather‌	⭐⭐ Poor	⭐⭐ Poor	Plastic-like, traps sweat
‌Full-grain cowhide‌	⭐⭐⭐⭐⭐ Excellent	⭐⭐⭐⭐⭐ Excellent	Naturally porous
‌Pigskin‌	⭐⭐⭐⭐⭐+ Best	⭐⭐⭐⭐⭐+ Best	Hair follicle pores = super breathable

 

The Source of Breathability

The breathability of grape leather mainly stems from its material composition and the specific design for its intended use:

• Natural fibers: Grape leather is made from natural plant fibers such as grape skins, seeds, and stems. These natural materials inherently possess some degree of breathability.
• Product design: Many products made of grape leather (especially footwear) also feature breathable inner linings to further enhance overall comfort.

 

Comparison

Material	Liquid Water	Air	Water Vapor
Animal leather	Moderate resistance	High	High
Grape leather (typical)	High resistance	Low–Moderate	Moderate
PU synthetic leather	High resistance	Low	Low–Moderate
Cotton fabric	Permeable	High	High

 

Can the Permeability Be Adjusted?

Yes. Manufacturers can alter the permeability in the following ways:

• Using thinner coatings.
• Introducing microporous structures.
• Selecting different bio-based or synthetic adhesives.
• Choosing a more breathable backing fabric.

These changes usually require trade-offs. Increasing permeability can enhance comfort, but it may also reduce waterproof performance or durability.

Is Grape Leather Good for Making Bags?

Yes. Grape Leather is a high-performance and innovative eco-friendly material suitable for making bags, especially appealing to consumers who pursue sustainable fashion and veganism.

It has already achieved a very close resemblance to traditional leather in terms of touch, appearance and daily durability, and has been adopted by well-known brands such as Stella McCartney and Bentley.

However, the long-term durability of Grape Leather still falls short of top-quality animal leather, and most products are not 100% biodegradable.

Most products on the market are not 100% made of grape, and usually contain synthetic components such as polyurethane (PU) to enhance durability and flexibility.

**Kombucha (com	Clutch / cardholder only	Decor-grade; not a real bag material
Mylo​	Clutch / small bag (2–4 yr, paused)	Softest hand, wet weak

 

Best Bag Types for Grape Leather

Style	Suitability
Tote bags	Light to medium loads; high visibility for the material
Crossbody and shoulder bags	Benefit from lightweight quality
Clutches and wallets	Low-stress use; texture shines
Backpacks (light duty)	Daily commuting, not heavy gear

Environmental Friendliness: Biodegradable, but with Conditions

• Pure natural form (without PU): 100% biodegradable. Under industrial composting conditions, it decomposes in approximately 20-30 days.
• Commercial product form: Due to the addition of water-based PU as a binder, it is not biodegradable and requires professional recycling systems for disposal.
• Carbon footprint advantages: Only 2.5 kg of grape residue (from 7 grape vines) is required per square meter, water usage is 95% reduced, and non-toxic tanning is used. This is far superior to chrome-tanned leather.
• Life Cycle Assessment (LCA) shows: The carbon emissions of grape leather are only 1/5 of those of animal leather, making it one of the most sustainable plant-based leathers currently available.

Market Applications and Brand Cases

Luxury Brand: Stella McCartney launched a handbag made of grape leather, whose price is similar to that of traditional leather products, and it is favored by consumers who value environmental protection.

Sustainable Brand: Vegea provides customized grape leather materials for fashion brands (including bag manufacturers), promoting the application of circular economy technology materials.

Specialty Brand: Some independent designers use grape leather to make limited edition handbags, highlighting their environmental concepts and unique craftsmanship.

Other Representative Brands:

Nicole Zizi Studio (USA): Launched grape leather handbags and wallets

COG Store (Italy): Focuses on grape leather shoes and cross-body bags, emphasizing “local raw materials + local production”

Design Advantages: Fine texture, natural color (deep red, wine brown, black), highly replicates the texture of genuine leather, suitable for high-end niche markets.

Limitations: Not yet in the supply chain of luxury brands such as Hermès and Gucci, limited production capacity, and prices higher than ordinary PU leather.

 

Current Challenges and User Instructions

• Lack of Long-Term Durability Data: There is no user feedback exceeding 3 years. The anti-aging and anti-ultraviolet properties need to be observed over a longer period.
• Vulnerable Supply Chain: Dependent on waste from European wine regions, not replicable globally. There is no large-scale production in China.
• “Fake Environmental Protection” Risk: Some merchants claim “100% natural”, but in fact contain a high proportion of PU. When purchasing, check the Vegea™ certification or the OEKO-TEX® standard.

 

If You Want to Make Grape Leather Bags (Specification List)

Be sure to use pH-stable fruit residue (Supplier issue #1 – VEGEA provides this material, while many other brands do not)

• Inner lining: Optional 120g rPET non-woven fabric (cheaper option) or cotton canvas (better crease, more environmentally friendly – similar to Bananatex style)
• Surface coating: If you want to pursue environmental protection, you can choose 2-3 mil bioplastic PU; if you want maximum wear resistance, use petroleum-based PU
• Design suggestion: Keep the load within 3 kilograms, avoid single-folded sharp corner flap, and strengthen the root of the shoulder strap (add a small plant brown or canvas patch above the shoulder strap)
• Do not: Use this material to make 5-kilogram commuting bags, rain gear bags, or heavy-duty zipper backpacks – this belongs to the Bananatex or leather category.

 

If You Are Planning to Purchase a Grape Leather Bag

Choose the VEGEA brand or brands that collaborate with it (such as H&M Conscious, some contemporary brands from the EU) → more reliable

Randomly purchasing “grape leather” products from Amazon or Alibaba → they are likely to have low fruit residue content and a thin surface layer → the usable period is approximately 12–18 months, after which the edges are prone to cracking.

Check points: fruit residue content, inner lining material, surface coating – the same three issues as for all plant-based materials.

 

Conclusion

Grape leather is a high-quality sustainable material that strikes a balance between environmental friendliness and performance. It provides a strong alternative to traditional leather for the fashion industry.

The durability of grape leather is comparable to that of ordinary PU synthetic leather. It can withstand 1-20,000 wear tests. By treating it with natural waxes or nano-coatings, its waterproof and stain-resistant properties can be enhanced.

Grape leather is suitable for daily fashion bags, brands that pursue the concept of environmental veganism, or those that are experimenting with innovative materials. It is particularly suitable for making fashion small bags/late-night bags, but not for heavy-duty totes for daily commuting.

However, grape leather still has shortcomings such as reliance on petrochemical-based adhesives and susceptibility to cracking when bent for a long time. In the future, it needs to be further improved in terms of sustainability and durability through technological optimization.
