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.
Convert the Mash & Boil to a still with optional Distlling Lid L14 and optional Copper Condensor P34.

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!

Mash & Boil
I really like the unit, the first one I got had some weirdness that it seems couldn't be reproduced back at the lab, but this unit works flawlessly. It maintains temp during the mash much better then I could with my picnic cooler. Once mash is completed rolling the temp to boiling is easy and efficient. I have a recirculation pump and connections so my next improvement will be an actual wart cooler. I have a DIY cooler but its not as efficient as the mash and boil so I will be upgrading.

I was just thinking of contacting you about my mash and boil, I got the new catalog the other day and the new ones can be converted to a still but not the older ones, is there any way to convert the older ones to accept this upgrade? you never know WTSHTF you may have to distill water to survive, I do have to say I love my mash and boil, I've been experimenting with all grain beer coming up with my own recipes and the mash and boil works great, my family and friends seem to enjoy my experiments, the mash and boil is a great product at a good price.

Quick Answer from William's: The new distilling lid will fit the previous edition Mash & Boil, but the previous edition Mash & Boil lacks clips to secure it tightly down. So my quick answer would be no, although if you found a way to clamp down the lid without clamps, it would certainly work.

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.

Hello, Do you think there would be a problem with the mash and boil sharing an outlet (separate plug same outlet) with a robobrew or grainfather? Thinking of using it as a vessel for sparge water.
If you set the Mash & Boil at its minimum setting, 1000 watts, it will use about 8.5 amps. A Robobrew or Grainfather at full power (1600 watts) uses about 14 amps, so combined, this is too many amps for one circuit and is not recommended.

Can the mash and boil be used to do extract also?
Yes, but you will need to turn off the unit when mixing the malt extract in, to prevent the syrup from burning on the bottom.  So you would get the water boiling, turn off the power, stir in the syrup, and then when the syrup is completely dissolved, turn it back on again.

Hello, How long is the cord that comes with it? What happens if you don't use a GFCI outlet but just a regular three prong outlet? How heavy is the mash tube when saturated with grain? Does it need two people to pick it up?
The cord is 5'. It will work without a GFCI but safety will be compromised. The grain basket weighs about 37 pounds when you lift it and twist to start sparging, and is not hard to lift with one person.

PS: We are currently out of stock, but will have more around September 4th.
