Brewery professionals, this YaeTek 5-gallon stainless steel keg is built to commercial standards and designed to handle the demands of professional brewing operations! The 304 food-grade stainless steel construction is corrosion-resistant and easy to clean, making it ideal for beer, wine, kombucha, or cold brew coffee. It comes with a standard D system Sankey valve already installed - the drop-in design is secured with a stainless spiral retaining ring that prevents tampering. The TIG-welded seams are smooth and consistent without burn residue, reducing contamination risks. At 16.8 inches in diameter and 23.25 inches tall (plus about 5.5 inches for the coupler), it's the standard sixth barrel size used by breweries worldwide. The 2.0mm thick top and bottom chimes are rolled 20% wider, making them stronger and easier to grip during handling. Weighing about 30 pounds empty, it feels substantial and durable. The keg has been chemically descaled and fully passivated for a clean, sanitary surface ready for use. Important note - this is for COMMERCIAL USE ONLY, as home brewers typically lack the specialized equipment needed to properly clean and sanitize this style of keg. The quality meets ISO 9001:2000 certification standards, and it's clearly built for long-term service in professional environments. Whether you're expanding your brewery's keg fleet or replacing older units, this keg delivers the reliability and performance you need for consistent product quality and efficient operations. The construction feels premium throughout, and it integrates seamlessly with standard commercial dispensing systems.
