FWIW, I stir frequently, about every 5 minutes, both to avoid any potential for scorching (if the heat is on) and I figure more homogeneous solution will translate into better conversion efficiency and more accurate thermometer readings.

I'll be keeping a little heat going with my induction plate to maintain temps so I guess it would be a good idea to stir more often.

How long of a mash time does everyone do? I'm guessing the larger grain amounts should probably go longer? I'm only doing 2.5 gl brews with 4-8 lbs of grain so I'm thinking 60 min should be more than enough?

I do 20 min at 104 F for dough in, 60 min at my sacch rest (149-155 depending on the beer), and 10 min at 168-170 for mash out. ~80-81% efficiency on everything I've done recently, including a 1.100 monster.

ok.. to answer a few of the previous posts.

yes I mash out. I do it as I feel it helps my efficiency. will not mashing out ruin the beer? no.

I have both a bag sewn by my wife that is custom fit to my 10 gallon kettle and a bag made by CustomBIAB for my keggle (see link in signature). Both work great. Get a bag made for you or make your own and you'll make great beer either way.

I stir my grains when I dough in to break up and dough balls.. I then stir again when heating to mashout. I don't add heat at all during the 90 minute mash and only drop temps by 2-3 degrees.

I also make my own recipes for the most part. That said, BIAB is all grain brewing. use ANY all grain recipe and you'll be fine.

Mysticmead,
Do you find the 90 min mash necessary for complete conversion or are you just playing it safe?

I have been experimenting and find that 90 minutes increases my extraction. Below are figures from a recent brew and are fairly typical of my results.

15 minutes: 7.4 brix/1.0282 (mash temp 154F)
30 minutes: 7.8 brix/1.0298 (mash temp 154F)
45 minutes: 8.6 brix/1.0329 (mash temp 154F)
60 minutes: 10.0 brix/1.0384 (mash temp 152F)
75 minutes: 10.5 brix/1.0404 (mash temp 150F)
90 minutes: 11.2 brix/1.0432 (mash temp 150F)

Ramped up to 168 and rested at mashout for 10 minutes:

100 minutes: 11.4 brix/1.0440 (mash temp 167F)

As I am oft to repeat ad nauseam: "Disregard the conventional "facts" and try things for yourself to see what works for YOU".

I find it helps with conversion

Do either of you stir during the 90 min mash?

Only if something happens to wake me up during that 90 minute nap.
