This is a five year old Recirculating Infusion Mash System called the Brew Magic, manufactured by Sabco, the same Brew Magic that Sam Caglione started Dogfish Head Brewery. Mine is in excellent condition, I have had it for five years and been using it in my licensed nano-brewery for the past six months. It can make 10-12 gallons of very smooth high gravity ales and lagers. I love this brewing system, but I have to get something bigger - can't keep up with demand. It's set up for propane, has a computer controller connected to a heat exchanger and higher pressure burners than the newer Brew Magic's you can see at http://brewmagic.com/brew-magic-v350ms-system
