Clay wine jars were one of the earliest containers used for storing wine. 1000L glazed clay wine jar is carefully selected from natural high-quality clay and fired at high temperatures of 1100-1370 ℃. It has characteristics such as microporous breathability, ion exchange, temperature buffering, and microbial colonization, making it particularly suitable for wine brewing and aging storage. We seek to provide reliable solutions for customers in traditional wine brewing, wine aging and storage scenarios, to help their business development.
The Advantages Of Storing 1000L Glazed Clay Wine Jars
As a wine storage container that has been passed down for thousands of years, clay wine jars have demonstrated unique scientific value and practical advantages in modern winemaking techniques, especially suitable for natural wine, organic wine producers, small boutique wineries, organic certified wineries, and other scenarios. Compared with traditional storage containers, it has the following prominent core advantages:
1. Microoxygenation respiratory system
● Oxygen permeability: The clay tank has a permeability of approximately 0.002-0.005 ml/L · day; Oak barrel approximately 0.015ml/L · day
● Pore size: Clay jar: 0.1-10 μ m; Stainless steel tank: 0 μ m
● Biochemical effects:
● Tannin softening: promotes polyphenol polymerization (tartrate conversion rate increased by 18%)
● Reduced odor elimination: H ₂ S oxidation efficiency reaches 92% (stainless steel tank only 35%)
● Fresh flavor stimulation: Increased glutamate release by 2.3 times
Case: Rioja region experiment in Spain: After 24 months of aging in ceramic jars, the proportion of rough tannins in Tempranillo decreased by 37%, and the taste was similar to that of 5-year oak barrel aging.
2. Disruptive breakthrough in economic benefits
● Space and operation costs
| Project | 500l Pottery Jar | Same Capacity Oak Barrel | Steel Tank |
| Cover An Area | 0.8m ² (Stackable In 3 Layers) | 1.5m ² (Single Layer) | 0.7m² |
| Annual Maintenance Fee | ￥ 200 (Rinse With Clean Water) | ￥ 2000 (Refurbished+Sterilized) | ￥ 1500 (Cip System) |
| Service Life | 50+Years | 5 Years | 20 Years |
Calculation example (for reference only, the economic benefits may vary depending on the application scenarios of different customers, and specific calculations will be made according to the actual situation of each customer):
Small winery uses 10 pottery jars vs oak barrels → 10-year savings: approximately $250000 (including equipment, maintenance, and space costs)
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 |
The Suitable Scenarios For 1000L Glazed Clay Wine Jars
As a reliable 1000L glazed clay wine jars supplier in China, Shunfa provides different types of ceramic jars. The company has been seeking to provide high-quality ceramic jars and customized ceramic jar solutions for customers in different scenarios, helping to promote business development. Ceramic jars are the preferred choice for the following scenarios
1. Natural wine and organic wine;
2. Pursuing mineral flavor;
3. Small winery.
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.
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.
