Default Stir, RIMS, HERMS ... non-insulated systems.

While in the process of building a stirring system for my Mash tun, I read thru old posts and it seems like a new survey might be in order. Obviously, there's time and cost associated with adding a stirring, RIMS or HERMS so the focus should be on results or expected results of this investment. Guessing that those with isolated, insulated tuns won't see the value of stirring the mash, but those with the option to add heat and/or step mash would see some benefit if nothing more than consistent temperatures in the grain bed.

I used a drill motor (incl. an old satellite mount) and mud mixer to add continual stirring to my tun. I trickle heat thru a gas burner and add blasts to rectify any large temperature fluctuations as well as when bringing the mash up to the next temperature step. I was getting huge temperature gradients thru the mash prior to this latest improvement.

Default

i use an insulated cooler for the MLT, but I don't put the lid on and i don't stir my mash. I circulate through a HERMS coil to maintain temps.

I have checked the temp gradient in most of my brews by using a probe at the point where the wort comes out of the heater and back into the MLT, another probe thermometer in a thermowell located in the middle of the grain bed, and a floating thermometer that is jammed down into the MLT so that the tip touches the false bottom.

I have seen, at most, a 1* temp difference between my three probes.
