Mueller® has been building beer fermentation vessels for over 50 years, specializing in custom solutions for breweries of all sizes. We have designed and built thousands of fermenters in a wide range of shapes and sizes, including indoor, outdoor, leg-mounted, roof-mounted, and skirt-mounted options. Our capabilities include shop-built and custom-designed tanks up to 1,800 BBLs, with the ability to build even larger tanks on-site through our trusted vendor network. In addition to custom solutions, we offer a standard line of fermenters, ranging from 15 BBLs to 120 BBLs, that combine the best features of our custom designs with our hallmark quality craftsmanship.
