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.

Mash tun
Very nicely designed for easy use but use a larger diameter filtering plate.
September 30, 2015
Just one problem...
In general, I love the cooler. I bought the whole kit, so I got the false-bottom and the valve too. I had been using a rectangular Coleman Stacker 48 can cooler, with a custom BIAB mesh bag, but I wanted to stack my MLT on top of the HLT (kinda like a Blichmann BrewEasy. In a way, my whole system was designed around using the stacking coolers as a true RIMS system. The RIMS recirculated the water in the lower cooler, until the strike temperature, then the output was diverted to the upper cooler (MLT), and I step mashed... I couldn't boil in the system, so I went to a Bayou classic 15 gallon with a Blichmann Boilcoil, made a spacer, and mounted the Fermenter's Favorite Cooler (MLT) on the upper deck. The problem occurred when I mounted the Blichmann AutoSparge valve. The wall of the cooler is WAAY thinner than the Coleman cooler. When I moved my sparge valve to the new cooler, it sags dreadfully from the weight of the device. I tried backing it up with a fender washer, but it still lacks support. When the MLT is full, it is a bit better, because the mash water supports the valve ball. The next thing I will try is bonding a piece of 60 thousandths Kydex to the inside surface. Not exactly sure how I will do it (probably JB Weld or silicone bathtub caulk)...

Response from Northern Brewer
Thanks for the review! Sounds like a nice set up. Did you refill the insulation when you installed the auto sparge

That could help prevent sagging

not sure

let us know if we can help in any way!

great product! cooler mash
quick shipping !

Works great. Holds temperature better than I'd expected!
September 30, 2015
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.

Good stuff!
This mash tun was delivered promptly and helped me step up my game with brewing. I did an Irish stout with this and it turned out awesome!

Fermenter's Favoriite Mash/Lauter Tun
Very nicely made tun with a very good false bottom. I particularly like the way the top seals.

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.

This is exactly what I needed to be able to all grain brew. Comes with assembly required but it is simple enough.

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!
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
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!
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.
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.
Can I upgrade this to a stainless steel value?
