Our kettles was designed and built with quality in mind. All of our kettles are made with 304 American stainless and features a thick 12 gage bottom to distribute the heat helping to eliminate any hot spots. The side wall is constructed with 14 gage material with a beautiful brushed finished outside and a food grade machined finish on the inside. Tri-clamp fittings come standard on all kettles. You can purchase a bare bones kettle with ferrules only or just go for it and purchase a kettle with all of the options. Either way these are kettles that any brewer would be proud to have as part of their brewing equipment.
