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.

Outstanding product with poor packaging
PRO - IT REALLY, REALLY WORKS!: I'm very pleased with the performance. Hit my numbers perfectly on the first batch. I was concerned that it wouldn't hold a strong boil or heat painfully slow, and neither has happened. You'll read that some people are adding insulation, but I can't imagine needing that...unless you want to reach a boil 5 minutes faster? or are brewing on a frozen tundra? 

CON - PACKAGING: As stated previously in reviews, the box that Williams ships the unit in is not very protective. Mine arrived with a few small cosmetic dents on the front, and the handle of the ball valve had the end of it's plastic coating scratched off, as the handle was poking out of the side of the box. The latter could have been easily avoided if they simply closed the valve before shipping so that the handle isn't sticking annoying lack of attention to detail, but I can forgive it as the unit itself is great.

Loving electric!
I'm so glad I made this purchase. No more babysitting a propane burner. Waking up to hot water is such a bonus!

Nice Value, but better packaging to avoid dents
First it's a great unit and I believe it will be very popular amongst home brewers.  It's a great value and works as advertised.  The only problem I have is with the packaging. Mine arrived with a big crease that penetrated the inner of the dual walls.  I was able to tap it out with a rubber mallet, but the outer crease remains.  It appears to be only cosmetic. Williams offered to replace it, but I'm going to continue to use it for a bit and I'll just hang on to it, if there are no functional issues.

Makes brewing great
This is one fantastic product. So far I have done  2 brews with it. First was a blue moon  clone and today a Maibock. The blue moon  turned out fantastic and I chalk  that  up to  the Brewers Edge. No doubt the Maibock will be good  too.  Great product. Give it a try.

Can the mash and boil do small batches or just the typical 5 gallon batches?
It is not recommended for anything less than a 2.5 gallon batch.

Can you add a pump to create a Recirculating Infusion Mash System? And if that works could I then manually change the temperature to do a step mash?
Some of our customers have done this, although we do not have a kit for this. It is possible to manually change the temperature by just setting a new temperature on the digital control at any time during the mash. This is manual, and the control cannot be programmed to switch temperatures on its own.

I use Brewsmith software and was wondering if you might have already created or have the data to put the mash and boil into the equipment portion of the software?
We are working on it. Thanks for the suggestion.

So just got the unit....set it at 166 and waited until it got there. Then when I tried to hold it there, it went all the way to 160. This is disappointing as a mash needs to be more dialed in than that. Any tips?
The Mash & Boil has a 6° differential to prevent rapid cycling and wear to the heating element, which means if you set it to 166, it will get there and then turn off and wait until it drops 6° to 160°.  It should then turn back on and go back up to 166°.

This is generally not a problem when striking the mash, as long as you hit it at 166°, and mix in the grain then.
