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.

First All Grain
I can use the Mash and Boil in the kitchen.  It takes up little space.  It's easy to use and clean.  What a great deal for $299!

Great Product
My first all grain batch is going great. Excellent product! Probably couldn't afford to go all grain otherwise.

Novice Brewer
I purchased the Mash and Brew after trying to brew with whole grains using other methods, I am 100% pleased with how easy it is to brew a 5 gallon batch using the Mash and brew pot, I'm a novice brewer still fairly new to brewing I like how easy it is to use compared to other methods, there was a little more fluctuation in temperature during the cooking cycle than I thought there should be but after contacting customer service my questions were answered in a timely manner and resolved, Thank you for a great product!

Can't wait to brew again!
I live in an apartment and don't have much space for brewing but this unit allows me to do 5 gallon all grain in my kitchen. The single unit saves valuable space in my kitchen. Plus the timer on it saves time. Waking up to water already at 165 saved me so much time on brew day. Wake up, dump in the grains, and then finish waking up until the mash finished. I can't wait for my next brew day!

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.

How would you suggest using the Mash and Boil to do a batch sparge? Seems like it might be tricky with the elevated grain basket having a false bottom.
The Mash & Boil is not designed for batch sparging, as it has a sparging basket that elevates. You also cannot do brew in a bag (unless you use the sparging basket and line the basket with the grain bag).  If you take out the sparging basket and line the unit with a grain bag, it will set off the ER4 error code because the bag will block heat circulation.

What is the minimum amount you can boil with this unit?
A 2.5 gallon batch is as small as you want to go with this unit.

How much does it weight?
It weighs 17 pounds when out of the box with the sparging basket inside empty.

Can I use this as a mash tun only? How much wort is below the false bottom?
Yes you can, there is 1/2" of space below the sparging basket (it has a sparging basket instead of a false bottom).  This 1/2" holds about 1/3 gallon of wort.
