500L unglazed clay wine jars can achieve micro oxidation, temperature buffering, humidity regulation, unique mineral effects, and potential support for microbial communities. They can soften the wine body, develop complex flavors, increase mineral texture, stabilize the fermentation process, and ultimately shape a unique, rounded, complex, and more “natural” and “terroir” expressing wine style. Very suitable for cellar aging. This 500 liter unglazed clay wine jar is made of natural clay and is molded through high-temperature firing, specifically designed for fermentation.

Core Features Of 500L Unglazed Clay Wine Jars
| Characteristic | Scientific Mechanism | Brewing Value |
| Intelligent Micro Oxygen Permeation | 0.1-10 μ M Micropores (≈ Human Capillaries) | Tannin Softening Increased By 23%, Reducing Flavor By 92% |
| Thermal Inertia Temperature Control | Thermal Conductivity Of 2.5w/(M · K)+Heat Capacity Buffer | Power Outage For 24 Hours, Temperature Rise ≤ 2 ℃ |
| Mineral Ion Engine | K ⁺/Sr ² ⁺/Ba ² ⁺ Plasma Slow-Release | Give Flint A Mineral Like Texture And Inhibit Tartaric Acid |
| Pressure Resistant Structure | 3cm Thick Bottom (Load-Bearing Capacity Of 2.5 Tons) | Supports 3-Layer Stacking, Saving 40% Of Land |
| Ecological Sustainability | Burning Carbon Emission 600kg Co ₂ E (Stainless Steel 33%) | Scrap Ceramic Powder Can Be Used As Fertilizer For Vineyards |
| Cultural Carrier | Hand Drawn Intangible Cultural Heritage Craftsmanship | Wine Premium Of 30-50% |
Core Difference Between Glazed Clay Wine Jars And Unglazed Clay Wine Jars
| Comparing Dimensions | Unglazed Pottery Jar | Glazed Pottery Jar | Explanation Of Scientific Principles |
| Breathability | ▲ High (Microporous Open) | ▼ Extremely Low (Glaze Layer Sealed) | After High-Temperature Melting Of Glaze, It Blocks The Pores Of Clay |
| Oxidation Rate | 0.8-1.2ml O ₂/L · Month (Promotes Aging) | 0.05-0.1ml O ₂/L · Month (Approximately Stainless Steel) | The Microporous Structure Allows For Slow Permeation Of Oxygen |
| Mineral Dissolution | ▲ Significant (Calcium/Iron/Manganese Ions Increase Mineral Sensitivity) | ▼ Trace (Glaze Layer Barrier) | Minerals In Clay Come Into Direct Contact With Liquor |
| Acid Alkali Effect | Ph Value Increases By 0.3-0.5 (Weakly Alkaline Buffer) | Ph Change<0.1 (Neutral) | Clay Containing Carbonates Can Neutralize Some Acidity |
| Humidification | Bidirectional Regulation (Moisture Absorption/Release) | External Moisture Absorption Only | Capillary Action Endows Unglazed Pottery With The Ability To ‘Breathe’ |
| Cleaning Convenience | ▼ Difficulty (Pore Contamination, Chemical Agents Are Prohibited) | ▲ Easy (Smooth Glaze Surface, Can Be Soft Brushed For Cleaning) | Glazed Surface Forms A Glassy Sealing Layer |
| Service Life | 5-8 Years (Gradual Blockage Of Micropores) | 10-15 Years (Glaze Layer Protects The Body) | Tartaric Acid Crystallization Leads To A Decline In Permeability Of Unglazed Jars |
| Typical Alcohol Content Adaptation | 16% Abv (Inhibition Of Miscellaneous Bacteria) | Unrestricted (Including Low Alcohol Beverages) | Low Alcohol Content Is Prone To Contamination By Acetic Acid Bacteria In Unglazed Jars |
How To Choose 500L Unglazed Clay Wine Jars
Customers of different types and scales of brewing have different choices of ceramic jar containers. Therefore, we provide solution suggestions on how to choose container size reasonably for different brewing goals
● Natural wine brewing: 200-500L thin-walled cans.
● Mass production: 1000L buried Qvevri.
● Oxidation style development: customized porosity tank.
● Small wine cellar: can stack 500L cans.
How To Precisely Control The Micro Permeability Of Terracotta Pots? How To Ensure That There Will Be No Excessive Oxidation Or Leakage?
The production of Shunfa pottery jars uses a specific clay formula and high-temperature sintering technology above 1280 ℃ to form a stable microporous structure. Each pottery jar has undergone leakage testing and a testing report can be provided.
What Is The Minimum Order Quantity (Moq)? Can We Accept Small-Scale Trial Orders?
We support a tiered MOQ: the standard MOQ is 100 pieces, and the trial order can be reduced to 50 pieces (with shared mold costs);
Shared Container: Propose LCL to reduce the cost of small batch shipping;
Sample policy: Provide paid samples (which can be deducted from subsequent orders), accompanied by a complete quality inspection report.
Can We Customize The Logo, Size, Or Special Glaze Color?
Our customization process: submit design draft online → 2 3D rendering confirmation → 3 Sample making (2-3 weeks) → 4 output.
Customization options: LOGO, color, size, glaze color, etc. are available for selection.
How Should I Handle It Before First Use? How To Clean And Maintain It In Daily Life?
Pre treatment: Soak in salt water for 48 hours → rinse with clean water → dry naturally in the shade.
Cleaning: Use only a soft brush and warm water, do not use detergents.
