Welcome to Anping County Boli Hardware Wiremesh Products Factory, a trusted manufacturer since 1998 with over 25 years of metal fabrication experience, exporting annually between US$5 Million and US$10 Million to global markets including North America, Europe, Oceania, and Southeast Asia. Our Oak Barrel with a Viewing Window, 50L, 18mm Thick, 304 Stainless Steel Rings is engineered for both professional winemakers and home enthusiasts who demand full visibility into the aging process without sacrificing authenticity. This barrel combines traditional craftsmanship with modern convenience, allowing you to monitor the color, clarity, and sediment development of your wine or spirit through a specially designed tempered glass window.
Crafted from premium 18mm thick French oak staves, this barrel provides optimal oxygenation and flavor extraction for wines, whiskeys, brandies, and other spirits. The 50-liter capacity (approximately 13.2 gallons) is ideal for small-batch production, aging trials, or decorative display. Each barrel is reinforced with 304 stainless steel rings that offer superior corrosion resistance and structural integrity compared to traditional iron or carbon steel hoops, ensuring long-lasting performance even in humid environments.
- Viewing Window Excellence: A 10cm x 8cm tempered glass window is precision-embedded in the barrel head, sealed with food-grade silicone gasket to prevent leakage. The glass is UV-resistant and shatterproof, providing a clear view of the liquid inside without disturbing the aging process.
- Premium Wood Selection: Staves are air-dried for 18-24 months and kiln-dried to moisture content below 8%, minimizing cracking and ensuring consistent flavor release. The wood is sourced from sustainably managed forests in France.
- 304 Stainless Steel Rings: Six heavy-duty rings (3 per head) are cold-rolled for tight fit, with a brushed finish that resists tarnishing. The stainless steel material is non-reactive and easy to clean, unlike traditional iron that can rust.
- Leak-Proof Design: Each stave is precision-machined and fitted with a slight bevel for tight interlocking. The barrel is water-tested at 1.5 bar pressure before shipment, ensuring zero leakage.
- Customizable Options: Available with optional spigot, bung hole, charring level (light/medium/heavy), and brand engraving upon request. The viewing window can be placed on either barrel head.

Benefits for Your Maturation Process: The 18mm thickness provides a slower, more controlled oxygen exchange compared to thinner barrels (e.g., 10-15mm), which is ideal for long-term aging of spirits like whiskey or brandy. The 50L size reduces the angel's share (evaporation loss) relative to larger barrels, making it cost-effective for small producers. The stainless steel rings eliminate the risk of rust stains on the barrel exterior and maintain the wood's ability to breathe evenly. The viewing window eliminates the need to draw samples frequently, preserving the integrity of the aging batch and reducing oxygen exposure.
Every barrel undergoes rigorous quality control at our factory in Hengshui, Hebei. We test each unit for water tightness, glass seal integrity, and ring compression. With over two decades of export experience shipping to 10+ global markets via major ports (Tianjin, Qingdao, Shanghai, Foshan), we ensure secure packaging and timely delivery. Our annual export volume of US$5-10 million reflects the trust our international clients place in our products. We offer a 12-month warranty against manufacturing defects and provide after-sales technical support for barrel maintenance.

Frequently Asked Questions
-
Can I use this barrel for vinegar or beer aging?
Yes, the barrel is suitable for any liquid that requires oak aging, including vinegar, beer, and even hot sauce. However, for beer, ensure the barrel is properly sanitized before use. -
How do I clean the viewing window without damaging the seal?
Use a soft, damp cloth with mild soap. Avoid abrasive cleaners. The window is sealed with a food-grade silicone gasket that can withstand gentle cleaning. Do not use high-pressure water directly on the glass edge. -
Is the barrel charred or toasted inside?
Standard is medium toast (20-25 minutes at 180°C). We offer light, medium, heavy, and alligator charring upon request. Please specify your preference when ordering. -
What is the expected lifespan of the barrel?
With proper care (cleaning, occasional refilling, and storage in a cool, humid environment), the barrel can last 3-5 years for active aging. The stainless steel rings will not rust, extending the structural life beyond traditional barrels. -
Can I order a barrel with a spigot or bung hole?
Yes, we can add a stainless steel spigot (with or without ball valve) and a standard #8 bung hole. Additional charges may apply. Please contact our sales team for customization. -
Do you offer samples for testing?
Yes, we can provide a single sample barrel (FOB price) for evaluation. For larger orders, we can also arrange a pre-production sample. -
How is the barrel packed for export?
Each barrel is individually wrapped in bubble film, then placed in a reinforced plywood crate with foam padding. For container shipments, we use palletized packing to minimize movement. -
What is the minimum order quantity (MOQ)?
Our standard MOQ is 10 units for standard specifications. For custom specifications (e.g., special charring, engraving), MOQ is 50 units. We can be flexible for trial orders.
