This mash tun is for the brewer who wants to get deadly serious about their mash consistency and conversion. This isn't your run-of-the-mill mush tun, either. This bad boy is made with dual-wall (foam insulated) 304 stainless steel, features a 5º sloped bottom and center drain for easy vorlaufing and transfer, internal volume markings (in both liters and gallons) for accurate readings, a false bottom with a silicone gasket, precision LCD thermometer, three-piece ball valve, thermowell, and a foam-insulated lid for heat-retention. It doesn't get any better than this, folks!

    SS Brewtech 20 gallon mash tun

    Posted by ralph z. on Jan 27th 2017

    This mash tun is very well built and worth the extra $100 over the similar competitive unit. I have been brewing since 1992 but, never used a manometer before. It makes finding the right runoff rate easy! I actually give this mash tun 4 1/2 stars because of the digital thermometer. Just my experienced opinion but, batteries dying during the critical mash process would rate up there with running out of LPG during the boil. An option for a calibrated analog thermometer would put it at 5 stars. Sure you can stock spare batteries but, will you find them and will they still be good when you need them? The only other minor complaint I have is that the vorlauf attachment was unavailable from Homebrew Supply at the time I purchased. Well it's time to brew a nice Marzen! Eins, Twei, Drei, Suffa! Prost!

    I received my mash tun quickly and packaged perfectly! I brewed with it yesterday and I'm really impressed, it held temperature within .5 degree for over an hour plus with no head space I dropped my water volume by over a gallon. I wish I had bought one earlier! Thanks HomeBrew Supply!
