The new and improved Fermenter’s Favorites® cooler assembly is the most affordable mash/lauter tun in all-grain brewing, loaded with brewing power for superior sparging and exceptional efficiency that’s mash-ready right out of the box.

Upgraded to ensure a tight seal, our insulated Fermenter’s Favorites® Mash/Lauter Tun cooler features a silicone-reinforced valve port for a leak-free brew day and arrives mash-ready out-of-the-box for you to get brewing, complete with a brass ball valve offering superior flow control that allows you to achieve the optimal sparge rate for any batch size.

Improved effectiveness in keeping grain particles out of your wort, the newly redesigned smooth-edged Titan universal false bottom promotes clear wort with half the dead space of traditional domed false bottoms, delivering high mash yields and eliminating scratched cooler walls.

Increased flexibility to brew bigger beers—the Fermenter’s Favorites® 10 gallon cooler has an expanded full capacity of 11.7 gallons for brewing five to ten gallon batches.

Worked great! Made brewing life a lot easier.
Filled my 10 gal (11.7 total gal) mash tun with the recommended amount of hot (175°) water for my grain bill and dropped in my grains. The water hit a perfect 158° and stayed there for over 30 minutes. After stirring many, many times and keeping a temperature probe submerged in my mash (the lid is perfect for popping it into place and still having just enough room to let a wired probe dangle down inside) and it finally got down to 154° at the end of an hour. Wow, only a 4 degree drop over an hour's worth of opening the top and stirring.... Not once did the mashing or lautering phase develop any problems. The thing worked like a champ and drained easily (too fast, really! I'll have to learn how to keep it sloooowwww) and cleaned up in a snap.The second tun held my other reserve of 175° sparge water for over an hour (with lid sealed) and temperature only dropped 1 degree.My only negative against it is the instructions (unless I somehow missed them, or misread them) weren't very clear on how to assemble the valve conversion assembly and mount in the spigot hole. It took several minutes of trying different combinations to get the valve spigot to stay in place. Worked great after that though! And there should be a big warning painted on the side: "Close valves before brewing!!" Learned the hard way what 175° water felt like, running down the inside of my shoe and on my foot!! ;-)Would buy again! Well-built and very solid construction, very durable. Should last many, many brewing sessions.
Mash tun
Very nicely designed for easy use but use a larger diameter filtering plate.

Buy the 10 Gallon
This product came with everything I need to do a Batch sparge and works very well. I bought the 7 gallon for my 5-gallon beer setup in a batch sparge configuration. It works, however, I would buy the 10 gallon cooler next time. If you ever want to do party Gyles or really big beers, or even double batches the 10 gallon will serve you better.

Mash tun
It works good. Holds heat well

Holds Temperature
I've used this mash tun many times and it will hold temperature to within one or two degrees over 90 minutes even when used outdoors in very cool weather. It's light weight is a benefit when I have to dump heavy wet grain.

Works great. Holds temperature better than I'd expected!

It was a nice investment.
When I decided to make some equipment upgrades, a new mashtun was on my list. I have built cooler mashtuns before and could have done that again but this time I decided to get something better designed and built to be ready to go. I'm very happy with it. I bought the 7 gal setup for my 6 gal batches. It has held temps very well and the false bottom design eliminates the problems I have had before of grains getting under the false bottom and clogging the output. I do recommend rice hulls in every batch they save a lot of headaches.

Such a great setup, just wish the false bottom was a tad bit bigger.

I am using the 10G all grain brew kit from NB. I'm having issues during the sparge. The mash tun hose barb is too small. The wort barely trickles out even with the ball valve open full. I have tried this with just water in the mash tun with no grains and it still just trickles out. I'm using the materials that came with the kit. It seems like the inside or outside barb hose fitting needs to be bigger to create a better flow. Suggestions?
P A on May 6, 2016
BEST ANSWER: Hello Dean,

Thank you for choosing Northern Brewer! Is the tubing running from the false bottom to the inside hose barb fit snuggly on each hose barb? Also have you tried back flushing the mash tun to ensure that there is nothing blocking the flow? The 3/8" hose barbs are plenty large enough to get a good flow of wort, so I am thinking there is something else going on here. Can you by chance send in a a picture of how things are hooked up? That way we can better troubleshoot the issue at hand here. Let me know and we will get it figured out!
If I only brew 5 gallon batches, would the 7 gallon cooler suffice?
D F on Feb 9, 2016
BEST ANSWER: The 7 gallon coolers can handle a nice high gravity mash so is what we recommend for most 5 gallon batch size all grain brews. Anything over like 1070 - 1090 should probably be 'partial mash' and make up the difference with DME/LME, just more practical, and the 10 gallon coolers would ahave extra head space and a little more temp loss during the mash rests - so I would go 7 gallon. I hope this helps!
Are the lids screw on?
A shopper on Jan 22, 2017
BEST ANSWER: Yes, takes about two turns from start to finish
Does the mash tun have a screw on lid?
A shopper on Jan 24, 2017
BEST ANSWER: Yes it does and it works very well
what is the lauter dead space for this set-up?
isaiah p on Jun 5, 2017
BEST ANSWER: If you gravity drain the Mash Tun from at least a 3ft higher then the secondary vessel, there is almost no loss with the included false bottom, other than grain absorption which is a given. Just make sure to open the valve slowly to avoid a stuck mash and it will create a vacuum affect that will empty almost all the wort. I've never used a pump to drain mine, but I would image it would be as efficient if not a little more.
How tall is the cooler ?
A shopper on Aug 31, 2017
BEST ANSWER: The 7 gallon is 19" in height with the lid on. The 10 gallon is 21.25" in height with the lid on.
Does the 10 gal. Tun have an airlock port?
H O on Jun 12, 2016
BEST ANSWER: No, there are no airlock holes in the top of the Mash Tun coolers. -Mike W, Northern Brewer
How long can this mash tun hold a steady mash temperature for?
J A on Jun 7, 2016
BEST ANSWER: It will easily be able to hold your mash temperatures for the full hour and more; customers report, and we have found, that it works great and holds temp very well. -Mike W, Northern Brewer
I was wondering if it would be possible to add a thermometer. Possibly before the ball valve?
J R on Apr 17, 2016
BEST ANSWER: Perhaps, but it would not be easy, and might cause all sorts of problems as you'd need to drill through the insulated side of the cooler. You'd almost certainly have to use some sort of silicone to seal the hole. One way to add a thermometer to a tun is through the lid; it's safer to drill there and it won't be a leak-point. A person could use a long-probe digital thermometer, if it would reach down to the grain, or have a wired probe in the tun via a hole in the lid. -Mike W, Northern Brewer
Can anyone tell me how tall this is without the lid? Trying to configure a 3 tier rack and want to figure out how high this will sit.
R O on Mar 3, 2016
BEST ANSWER: Fermenter's Favorites Cooler Mash/Lauter Tun is 18-5/8" high w/ lid on and 17-7/8" w/ lid off.
Can I upgrade this to a stainless steel value?
A shopper on Feb 2, 2017
BEST ANSWER: Hi there,
This kit only comes with the bronze ball valve but we do sell a stainless steel ball valve that you could install yourself. Cheers!

B U on Mar 28, 2016
BEST ANSWER: The outside diameter is 15.5"
Are the plastic cooler and hoses Bph free?
M A on Jan 25, 2016
BEST ANSWER: Hello Mike,

Thank you for choosing Northern Brewer! The coolers and hoses are indeed BPA free. I hope that this information is helpful! Have a great day!
What is the shipping dimension and weight in case of 7gallon mashing tun?
E T on Aug 31, 2015
BEST ANSWER: The package should be roughly 14.5 inches x 14.5 inches x 20 inches and weighs about 10 lbs.
