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 Distlling Lid L14 and optional Copper Condensor P34.

Revolutionizes getting in to all grain
Just did a Pliny clone in the brewers edge mash and boil.  I've been brewing on various systems and I also have a 50 amp electric brewery I usually brew on.  After having a baby, I needed to find a way to get my brewing done while spending time with the fam.

This thing fits that bill.  I wish I would have had a system like this when starting all grain.  Simple, effective, cheap.  The pliny clone I did, went without a hitch.

Now considering getting a second one to do some parallel brewing!

Unpacked the unit and added water to learn how to use it. A leak, had to tighten up on the valve, was not tight. After that no problem. 
The day before brew day, filled the unit set the timer and strike temperature. The next day when I went out into the garage everything was ready to go. No problems.
But when I tried using my March Pump and pumping the hot wort through my plate chiller, it plugged up. Have to try something else. Maybe let the wort sit longer, up to an hour
Next time I'll pump the hot wort into my brew kettle which has a screen and the valve sits higher off the bottom. Then pump through my plate chiller.

I think if the valve on this unit was a little higher off the bottom, it would work better.
Outside of my plate chiller plugging up, the unit worked well, my brew day went off with less work. I think I'll be brewing more as the Mash & Boil takes a lot of work out of all grain brewing and less clean up.

Very good machine
I had a problem with the mash and boil at first..the gasket was a little chewed up and it leaked..i contacted williams they said they would send me a replacement at no charge..i got frustrated and decided to return...I am very glad i came to my senses..this think rocks and williams customer service is top notch..i brewed a stout and this thing boiled 6.5 gallons no problem, got good efficiency, and its very easy to use and holds temps pretty darn good and less gear to clean..i bet it would work even better with a pump..For 300 bucks you cant beat it..thank god i did not return it

A very good unit for the money
I've done 4 batches now with the Mash&Boil and it works very good and seems to have good efficiency, I use .30 strike water per LB of grain. Temps do seem to fluctuate a little more then I would like to see but doesn't seem to matter and I have a pump on it now and can recirculate a few times during the mash. My biggest complaint on it is where the reset is located on the bottom. It's mostly impossible to get to when full of hot wort., but I corrected that by having a access hole in the bottom of the cart I have it on, and it only tripped once the first time I used it and know why and was my fault. I've made some really good beer so far with this and highly recommend it to anyone wanting to go from extract to AG or any other system for that matter. It's a lot like BIAB but in my opinion a lot easier.

All grain All-in-One
I had brewed over 300 gallons of extract kits and was looking to get into the All grain game.  This was my first attempt using the Brewer's Edge system.  Turns out I made one of the best IPA's I've ever tasted!  One down side is the variance of the temperature range.  You need to stay on top of it to keep it in a smaller margin either boosting the larger heating unit to increase temp or recirculating with a large Pyrex container to cool down.  A large stainless steel paddler helps some in the cooling process.  Overall I am happy with the purchase and so are my friends that drink beer!

So, if I have the older Mash and Boil without lid clips, what are my options ? Would you sell the clips with, say, install instructions or a template or something ? Would really like to use the distilling equipment but can't afford to buy a new unit. HELP
We do not sell the clips separately, but the new distilling lid fits the older Mash & Boils, but you would need to find a way to secure it or clamp it down.

I would guess that the mashing process would cause some grain pieces to go through the bottom of the basket. Does a Vorlauf process where you run out wort and pour it into the top of the grain basket result in a clear wort for the boil phase?
Yes, some husk particles do get through, and pouring a quart of so of the first runnings off the sparge into the top of the grain bed will reduce this.  There will always be some husk particles that get through, however.

Does the lid that comes with the Mash & Boil have a gasket? Just wondering if I can drill a hole in the stock lid and install a stopper and airlock/blow-off tube.
No it does not, it comes with a lid that fits the top, but is not gasket sealed.

I see the Mash&Boil now has cover clips and a Optional Distilling Lid. Can these clips be bought separate?
No, these are welded onto the new Mash & Boil.
