An insulated, stainless steel Mashtun for hombrewing that will keep your mash at the temperature you set. Retains an amazing amount of heat since it is double walled with a layer of insulation between the two stainless walls. Unlike insulated plastic cooler the InfuSsion Mashtun is made of food safe stainless steel so you have no worries about the affect of heat on plastic.With cool features like an integrated center drain port, gasketed false bottom setup, etched volume markers, stainless hardware, and a digital thermometer, this is the ultimate mashtun!   

When Ss Brewtech tested against similar sized plastic cooler mash tuns, the Infussion dropped 5° F less over the course of a 60 minute mash. The center draining conical bottom vessel silicon gasketed false bottom minimizes the amount of water under the screen, what many brewers refer to as dead space, and allows for great efficiency. One of our favorite features is the simplest...the internal volume markers rid you forever of having to use a ruler to calculate the right amount of mash water.  

This is a great addition to any brewery, and with the additional upgrade kits in the pipeline like a Sparging System, Heating & Temp Control System the InfuSsion Mashtun will become of your favorite pieces of equipment for years to come!  

The 20 gal InfuSsion Mash Tun will also feasture a recirculation port near the top, as well as a Manometer to measure DP

Great piece of equipment. Makes brew day easier.

A great idea that needs a couple of tweaks.
I use this as part of a three vessel HERMS system. It is great but has two unfortunate (in my opinion) design flaws.

The first and most notable is the drain. The hole is way to small in diameter. This is fine for recirc but a pain in the butt when you want to clean it out after. If the drain was bigger, this thing would be amazing. You could just use the ball valve to control your flow rate.

The second issue is rather minor but annoying. After only three brew days the volume markings on the interior are already almost gone.

Holds temp well though.

Good Mash tun
Bought it and it works like it should. The MTS heater is a wast of money though.

Fits my needs and works as expected
As a HERMS recirculating mash user, the manometer is wonderful. It confirmed my coil restricts enough for a wide open DC pump application. I had some fine particle flow through, so I will be throttling the flow to see if this can be eliminated next time. Temp holding was spot on and it sped up the ramp times greatly over a single walled vessel.

SSBrewtech Mash Tun
Great addition to the brewery now that I'm doing half barrel brews. Plenty of room for mashing last batch was 42 pounds of grain and still left room to spare

Big step up from plastic mash-tuns.
High quality mash tun. Held 15 gallons of mash with only 2 degrees drop in 70 mins. Well constructed, nice insulated lid. Too bad it din’t come with tri-clamps.

It’s big and heavy. False bottom comes apart quickly for simple cleaning.

Worth every shiny penny
While expensive, this tun will keep your mash at temp with less than 1 degree of heat loss over the course of an hour and a half. My efficiency has improved by 10 percent!

My last mash tun
I kinda love this HEAVY beast. Sure, it’s a splurge, but it’s pretty awesome.

Better than my old Igloo
Bought this to have more room to make higher gravity 10 gal mashes. Only problem I have with this is I've found it impossible to set the grain bed. No matter how much time I spend recirculating the wort, I'll have grain bits flow through into my boil pot.

Killer Product
So I've used this mash tun for four brews now and I love it. Temperature drops range from 4-8 degrees for 60-90 minute long mashes. I also got the sparge arm so I could fly sparge (I think it's meant more for the 10 gal, but I'll mention that over on that product). Make sure you're not walking home from the post office when you get this bad boy because it's heavy! It's got that Ss durability feel to it which I really love. This thing was built to last. Make sure when you're dropping the false bottom in with it's gasket you have the gasket facing the right direction. I must've tried ten times before I realized it was the wrong direction. The fit is tight and it's really easy to slip the thing off over there when you're lowering it into place, but hey, that's what you want in a false bottom. Be sure to have a friend there to lift this thing up and into the dumpster. The weight of this product with 50-75 pounds of wetted grain makes it a pretty difficult lift to do solo five feet above the ground into a dumpster.
