Do you want to get into mashing but want something simple? The patented 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. Protected by U.S. patent D819,385 S.

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. (Fahrenheit only). It also features a delayed start timer, so you can program the Mash and Boil to turn on up to 23 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 Mash & Boiling Distilling Package (see at right).

I love it!

Review by Jim Clark on 3/30/2020

I love it!!! It works just as advertised. Made it so much easier to boil the mash and so much cleaner with the inner column. The temperature indicator leaves a bit to be desired.


Review by Chance Morehead on 2/25/2019

Mash temp jumps up to 170 when the thermostat is set at 150 customer service is terrible basically told me they where going to do nothing about it but put water in and seen if it would heat up even tho the problem comes in when your mashing not heating the water. Ruined two runs probably won't use this or recommend this product to anyone. Go with a competitor William's Brewing Responds: This unit was not purchased from William's. We asked you do a test by running the unit for 4 hours with water in it at your preset mash temperature to test the thermostat before returning it. This was not done. Without this information, we cannot tell if the thermostat is bad. We also offered you a prepaid return label so we could get it back here and fix it if the 4 hour test proved the thermostat was defective.

Review by Mitch on 12/25/2018

Grains had trouble straining. Temp fluctuates a 5 degrees either way. Solid product easy for cleanup. Recommend a pump for circulation.


Review by Bill on 12/24/2018

I was looking for an easier way to brew in the wintertime. This works perfectly. Instead of brewing 10 gallon batches in the garage, I can now easily brew 5 gallon batches in the kitchen. This makes all grain brewing so easy. I have used it 3 times in 4 weeks. Great product.

Q: How can I keep from getting bottom full of burnt on mash and popping off the element? I clean it off between every brew but ias soon as I start I get build up. Anything I can put on it to keep off build up during mash?

A: Fine particles can cause deposits and scorching. Grind your malt as coarse as you can without letting whole kernels through the mill which will help reduce the dust and the burnt deposits. Worst case, a battery powered drill and a wire brush can remove stubborn deposits.

Q: What is the typical grain mill setting for my crushed grains with this mash pot?

A: Grind as coarse as possible while still crushing all the husks. The best way to check for this is open the rollers up until some kernels come out whole, and then tighten up the gap a bit so the whole kernels get crushed.

Q: Is there a Mash and Boil profile for Beersmith?

A: Here is a link to one from the internet. We uploaded one to Beersmith about 5 years ago, but not sure if this is it or not.

Q: I’m having issues getting an active boil with my new mash and boil with pump equipment. I have set the temp as high as 220 F but it only reaches about 210 F and a very low boil. Boil off is only about a half gallon per hour. Any suggestions? Thanks.

A: It should reach 212 F but no higher as it is limited by the boiling point of water. Try a different outlet, and avoid using extension cords. Boil off of 1/2 to 3/4 gallon per hour is typical.

Q: Is it necessary/recommended to recirculate wort with this unit?

A: It is not necessary, you can infusion mash in this unit at one temperature. Some brewers like to drain a quart of so of wort during the mash and mix it into the top of the grain basket for a recirculation effect.
