The 25L glazed clay wine jar is made of high-quality clay and fired at temperatures above 1280 ℃. It is suitable for home winemakers, boutique wineries, and handmade distilleries. Clay walls can soften tannins, promote micro oxygen exchange, release minerals such as calcium, magnesium, and potassium, enhance flavor complexity, and provide natural aging conditions for high-quality wines. We are committed to providing reliable solutions for traditional wine brewing, aging and storage scenarios, and helping our customers’ business development.

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 |
25L Glazed Clay Wine Jars Are Suitable For Scenes
Winemakers often use 25L Glazed Clay Wine Jars in modern winemaking to create wines with specific styles and concepts., Shunfa has OEM/ODM capabilities and can provide customized solutions for customers with different scene needs.
● Wine making industry:
Georgian Qvevri pottery jar aging is a national level intangible cultural heritage, adopted by over 90% of traditional wineries; Many places in Spain and Portugal also continue the millennium old pottery jar aging process. Compared to oak barrels and stainless steel tanks, pottery aged wine has a premium of 20-50% and higher efficiency.
● Spirits and Strengthening the Liquor Industry:
Sherry wine from Spain, aged in ceramic jars, accounts for about 15% of the high-end production capacity. Mexican tequila and clay pot distillation (such as Tequila Ocho’s “Penca” series) enhance the roundness of the taste and become the core selling points of niche boutique factories.
● Traditional Asian Liquor Industry:
Chinese Huangjiu: Shaoxing intangible cultural heritage “Huadiao Wine” is aged in pottery jars, which promote esterification through breathability. The ancient Yue Longshan pottery jars have a reserve of over 2 million pieces.
Japanese Sake: The “Sh ō n” fermentation process uses ceramic jars to enhance microbial activity and taste.
Korean Maggi liquor: stored in pottery jars to delay spoilage, it is the core container of traditional markets.
● Craft Beer Revolution:
Sour beer/natural fermentation: Jester King from the United States and Cantillon from Belgium capture wild yeast (Brettanomyces) in pottery jars, increasing complexity by over 30%. Ceramic jar micro oxidation replaces oak barrels to reduce costs (such as Dry&Bitter distillery in Denmark). The global use of craft beer pottery jars is increasing by 12% annually (Craft Brewers Conference 202●.
● Fruit wine/experimental fermented drink:
Cider: Somerset aged apple cider from the UK, such as Hecks, reshapes traditional flavors.
FAQ
How To Precisely Control The Micro Permeability Of Pottery Jars? 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.
