Do you want to get into mashing but want something simple? The patent pending Brewer’s Edge® Mash & Boil makes it easy. No need for an outdoor burner, complicated brewing stand, or a 220 volt special circuit - it plugs into any 110 volt GFI household outlet. The Mash and Boil’s exclusive double wall stainless construction conserves heat to achieve a rolling boil with only 110 volts and 1600 watts, and its precise thermostat and internal sparging basket lets you mash and boil in the same vessel.

A typical brew day with the Mash & Boil begins with formulating your 5 gallon all grain recipe (up to 16 pounds of crushed grain can be mashed), and then heating your strike water to 162° F, the preset heat temperature. After 40 minutes or so, your strike water is 162° F, and you mix your crushed grain into the sparging basket already inside the Mash and Boil. The mash will cool to 152° or so, and then you set your thermostat to 150°, cover, and let mash for 1 hour. During this mash time you will need to separately heat 3 gallons of sparge water to 175° in a separate pot you provide. A thermometer hole is provided in the lid, in case you want to monitor the temperature of the top of the mash with any long probe analog or digital thermometer.
After one hour, lift the sparging bucket and lock on its included legs, and let the malt sugar drip into your Mash & Boil, which has now became a boiling pot. Turn the thermostat up to 218° F. and give it about 40 minutes to heat to a boil. During this time, ladle one gallon of hot sparge water at a time into the top of the sparging basket until you get to 5½ gallons. Now remove the grain basket, and when the boil begins, add your hops as per your recipe. Boil for 1 hour, and then cool with a suitable wort chiller (not included, our item E81 works well as does any immersion chiller that is up to 11" in diameter). Or use the stainless valve with ½” hose barb to run the wort through your external chiller.

The Mash & Boil features an adjustable thermostat with a range of 45° F. to 218° F. (switchable from Fahrenheit to Centigrade) with an adjustable run time preset at 3½ hours for safety. It also features a delayed start timer, so you can program the Mash and Boil to turn on up to 24 hours after setting. For example, load it with strike water, and have it set to be hot when you come home from work to save time. Intended for 5 gallon batches, maximum capacity is 7½ gallons. 28” tall closed, 40” tall with basket, 14” wide. A 5' power cord is included.
Convert the Mash & Boil to a still with optional Mash & Boiling Distilling Package (see at right).

Good Extract to All-Grain Transition
After using extract and partial mashes for almost 20 years I finally took the plunge into the all-grain arena.  This is an excellent way to do it, and I'm very happy with the purchase.  I've only brewed one batch so far, but everything works as advertised.  I brewed in the garage, which was about 50F, which pleased my wife because I'm finally out of the kitchen (at least for the hop's boil), and unit heated the water about the same as the stove.  It took an hour, maybe two, longer. but I think the time was due to the all-grain procedure and not the unit.  Mashing and sparging just takes longer, than extract, and I'm still figuring things out.  I still have to heat up the sparge water, and of course use the kitchen sink, so I'm not totally out of the house.  I got a hop leaf stuck in the valve, so I couldn't use it to drain the wort into the fermenter.  I think I'll try putting the hops in a grain bag next time.  Other than that the unit worked like a champ.  I highly recommend it.

I've had several setups, first stovetop-DM, then all-grain with a cooler mashtun on stovetop, then propane burner all-grain and finally this.

It is definitely smaller than my previous setups (I still have components, I could still do a LARGE all-grain mash with my 10 gal cooler if needed) this thing takes the cake and makes brew day easy.

The further I've gotten into brewing (about 3 years) the more honed my tastes have come and the less need I have had to make the "biggest baddest beer around". I have 4 taps I like to keep filled with great homebrew and having this helps immensely.

It's compact, the sparge process is simple, no need for pumps just open the spigot at the bottom, fill a container and dump it up top. While I do recommend double-milling your grain it still makes a good batch without it.

Transferring to the fermentor is a breeze!

The delayed start is nice for days I have the forethought to use it, especially with a mini RO setup.

I cannot recommend this thing enough.

More powerful than expected
I received the Mash and Boil as a gift for Christmas.  I promptly purchased ingredients and planned a batch of Janet’s Brown.  The ability of the unit to deal with the extremely low trmperatures on New Year’s Day was impressive.  I was Brewing in a 20 degree garage.  There were some hurdles, as you would expect when learning a new system, but I am very happy after my first brewday.  I look forward to many more.

I have seen some reviews which mentioned poor packaging. I just received mine today and I thought the packaging was very adequate - double box with bubble wrap between boxes and good polystyrene protection for the unit in the inner box. Arrived in great condition. I have two 'brews' on the go at present so may not use the unit for a week or more - will review again after use but looking forward to my next session !

Very happy with this product!
I have brewed two batches of beer with the Mash and Boil so far. Both times it was less than 50 degrees outside. The first batch took a really long time, 6+ hours, but that is because I used the Mash and Boil to heat up all my water. The second batch took less than 5 hours, but I was using my propane burner to heat up water to speed things up. When it comes to mashing I could not be happier with how easy it is to have everything in one kettle. The biggest complaint online I have seen is from the 6 degree hysteresis. I did find the temperature fluctuating a lot but the grain bed temperature stayed pretty consistent while I circulated the wort with a pyrex measuring cup. Lifting the grains out of the wort to rinse them is so much easier than sparging with three vessels. Both batches, even in the cold, had a nice rolling boil and stayed up to temperature. Because I had extra equipment I feel that this machine is worth it and I was able to have a very efficient brew day.

is there a hole in the lid? What size is it?
There is a 1/8" hole in the standard lid included with the Mash & Boil intended for a long stem dial or digital thermometer.

What do you do if you get condensation in the controller? Is the unit wrecked?
No, moisture has found its way inside the base which could be due to water under the base or a leak. Typically this happens when you place the unit on a wet surface, and the heat from the unit heats the puddle it is lying in, and moisture gets in through one of the bottom holes in the base.  To get rid of this, unplug the unit and turn it upside down. Leave it for 5 days to dry out and the moisture will disappear.

This also  could be an indication of a leak. A leak can be caused by the valve back nut not being tight enough. Check the back nut with a wrench to make sure it is tight to make sure this is not the problem.

Is it possible to use “The Trub Trapper” in my mash and boil?
We do not sell the Trub Trapper so we do not know for sure.
