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.

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.

Dry Run
Here's the initial run times with only water.
4:25pm 62* starting water, 6.5 gallons
5:33pm 164* temp hit and turned temp up to 220*.
 *An hour to get to temp, not impressive but it would give you time to get the grain crushed while waiting.
6:15pm Sitting at 215* and holding. 
 *Boil is better than I thought.
Hour boil-off rate was .5 gallon ( I'm used to 1.5 gallons ).

I'm satisfied with this.  I don't think I will miss trying to get the grain out of the water cooler and into a bag without making a mess.  Here is what I wanted to see, what the boil actually looked like.  Copy and Paste the link to see my boil, should quell any concerns.!AgnTVvRCSXf_hYkmbLtVPLHvoTUcDw

Great Product
So I have been looking for a way to get into all grain brewing in my tiny apartment for a year.  I couldn't afford the Grainfather on my grad school budget.  This is the perfect solution.  I have brewed twice and I am not disappointed.  I have boiled six and half gallons of wort with no problems at an elevation only slightly above sea level. I added a layer of heat wrap from the home center to help reach boil temp faster.  I paired this with the Mark II pump to recirculate.  That setup gives me most of the functionality of a Grandfather at a bargain price.

Brewers Edge Mash & Boil
 I have use this unit several times and it does a great job.  Before, I have to break the 5 gal all grain bill into two 5 gallon pots to handle the weight of the grain mash and monitor the temp.  Now its an easy one step process up to siphoning into the primary. I set it up on an egg crate to flow into the primary to eliminate a beer pump.  Does the same thing the Grainfather does,  except its $600 cheaper.  Cheers,  Steve

There seems to be a 10F rise after the heat shuts off... Mash temp set for 150F - bottom of the mash (M&B temp probe) is 160F and the top is ~148F... This is a significant gradient - have you used a long probe to figure out the real average mash temp?
We have not experienced this with .30 to .37 gallons of strike water per pound of crushed grain. An easy way to compensate is to pour a gallon out of the bottom and stir it in the top during mashing.

Hysteresis seems to be +0/-6F... is this consistent with your observations? Can this be changed?
There is a 5 degree differential which is preset and cannot be changed.  You will find the temperature of the mash will not vary as much as this.

How tight is the temp control; i.e. if the controller is set at 152, how much overshoot/undershoot can be expected.
About 3 degrees above or below is expected.
