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 (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.

The Mash & Boil was well packaged and arrived in perfect condition. I love that my whole system now fits on a small rolling cart.  I don’t have a sparge water heater, so I started off by heating about 6.75 gallons in the Mash & Boil to 172 degrees, transferring 3.5 gallons to a cooler for sparging later.  I added less than a quart of cold water to bring the rest down to mash temp. (It took about an hour and 20 minutes to heat 6.75 gallons from 55 degrees to 172, using an extra-large hoodie as a kettle jacket. Next time I'll set it to heat the water in advance).   When mashing, you definitely want to pull wort from the bottom spigot and stir into the top as described in the Mash & Boil blog to maintain temperature at the top of the mash. I'm going to try adding a recirculating pump later.  Set the temp to 218 while sparging and got a solid rolling boil in 30 min. Very satisfied with the Mash & Boil. Having an electric brewery with this kind of performance at this price is great!

Love It
I have used this twice within the first week that I have owned it. The simplicity of the controls is nice and it cuts down on the total time of brewing. So far I am very happy with it and I wish I would of bought this sooner

Yay indoor brewing
The unit arrived with a small crease in the outer metal due to either banding on a pallet or just lack of corner supports in the box. That did not affect the performance of this wonderful tower.
The ability to preset your strike water is very helpful for weekday brewing after work. Make sure you follow instructions as it does not get a rigorous boil and does not boil off nearly as much as I thought it would. It was a nice gentle boil and did not seem in danger of a boil-over when adding hops or anything.
Steam was not as big of an issue as I thought and I managed without a vent hood in my basement. Make sure you have proper chiller as my normal one could not sit on the bottom without submerging the input and output connections.
Overall I was really happy to not be freezing my butt off in the garage during a Michigan winter.

Love it!!
I have made 4 batches so far and it performed perfectly, Reached temps quickly and maintained them well! 
Incidentally, I ordered a Graincoat and turned it upside down! It fit perfectly!!

I highly recommend this unit and will be using it over and over!!
Love it!!!

First run

My first run I decided to go big and mashed 14 lbs of grain. I went with 4.5 gallons strike water. Set my temp for 166 F. Once I reached temp (about an hr) I began introducing crushed grain but at a slow rate. It got pretty dry fast. I had to pull wort off the bottom 4-5 times to get all the grain in. I did notice a rather large temp difference from bottom to top of mash, about 4-6 deg. It is a fairly small diameter to be mashing that much grain for sure. Boil temp was reached in about an hour. I set it for 214 but it never really hit a rolling boil. The biggest problem I had is at end of boil I killed the heat and threw in my wort chiller. I recirculate Ice water until cool. It seemed like the pot never fully shut off. I couldnt get below 105. All my ice melted after 30 min of trying to cool down. I shut the thermostat off I did not have the master power switch off, so I hope this was the problem. The jury is still out but I made a few mistakes. Ill try a smaller beer next brew day


William's Brewing Responds: To kill the heat turn the thermostat to off. This way, the unit will not be trying to heat while you want to cool. Turning the master power switch to off should solve this.

Heating elements all have a useful life span before they must be replaced. As I read earlier, the coil is not replaceable. What is the repair on this unit then for a burnt heating coil?
There is no repair, as the element is welded into the base of the boiler.

I just purchased this, really excited! If I wanted to add a dip tube, is this possible? If so, have you tried it with a dip tube?
As you can tell, the interior of the valve is smooth and not threaded. We have not tried a dip tube,but you will find after the boil that the wort below the level of the valve is full of trub and not all that desirable (especially if you use an immersion chiller). So we have not found after use that a dip tube would be a great thing, although it might be if you are using a plate or counterflow chiller.

Could a kettle screen be attached to the inside of the unit?
No, the included valve does not have female threads.

Can you run the controller in celsius?
Yes, it is easy to change the programming from Fahrenheit to Celsius. Scroll down to the bottom of the product description for more on this.
