Q: There seems to be a 10F rise after the heat shuts off... Mash temp set for 150F - bottom of the mash (M&B temp probe) is 160F and the top is ~148F... This is a significant gradient - have you used a long probe to figure out the real average mash temp?

A: We have not experienced this with .30 to .37 gallons of strike water per pound of crushed grain. An easy way to compensate is to pour a gallon out of the bottom and stir it in the top during mashing.

Q: Hysteresis seems to be +0/-6F... is this consistent with your observations? Can this be changed?

A: There is a 5 degree differential which is preset and cannot be changed. You will find the temperature of the mash will not vary as much as this.

Q: How tight is the temp control; i.e. if the controller is set at 152, how much overshoot/undershoot can be expected.

A: About 3 degrees above or below is expected.

Q: Are the handles on the sides strong enough to lift the entire unit with a full 5-gallons of wort? I am making an electric lift to raise the grain basket. It would be cool to use it to raise the entire unit high enough to drain the wort into the fermenter

A: When full of 5 gallons of scalding wort, the Mash & Boil should not be lifted by its handles.

Q: I brewed a 13.5 lb recipe as my first trial run. I normally get a 1.072-1.075 efficiency. I was down to 1.063 using the M&B. It seemed like the spent grain had a few miles still left in the tank. Any ideas on how to improve my efficiency?

A: Try using .30 gallons of strike water per pound of grain. See our blog for more on this: https://www.williamsbrewing.com/Mash-and-Boil-Blog.aspx
