Default How often to stir mash?

After doughing in and stirring like crazy, I put my lid back on and wait. I usually only stir once toward the very end when I do my iodine test. Then i let the mash settle again before vorlauf. My question is...how often do you guys stir your mash? and for how long? As usual, thanks for the help.

I am not much of an Expert (YET), but I got 74% yesterday...and I didn't stir at all until I was ready to begin vorlauf. (Also 90 minute Mash)

15 to 30 minute intervals. I havent been able to see any difference in efficiency when stirring more/less often so I dont worry about it too much, it seems the enzymes go where they're needed.

I usually check the temperature 15 minutes into the mash and stir it pretty quick to prevent any heat from escaping. I may do this once more after another 20 minutes.

I also do stirs around every 15 minutes to 25 minutes, mostly when I'm doing temp checks etc. I don't think it makes a difference but hey I like the smell of a good mash.

I think, the taller the MLT the more often you have to stir, because there is bigger temperature difference between top an bottom

All stirring does is cause more heat loss. Leave the mash alone. Stir once when doughing in. The enzymes don't need to be persuaded into finding starch.

After doughing in, I don't stir until I add my sparge water. I also don't do a mashout. I check conversion on the first runnings during the first quart of vorlauf. Last batch was 79% efficiency.

if you're step mashing in a picnic cooler (ie, by adding hot water, not by adding heat), would you stir or not stir with every addition?

also, how much do you stir when you dough in? so far i've been stirring like crazy, but only for 30 seconds to a minute max. I've been getting low efficiencies (60-65).
