Default First BIAB - Can someone please review my proceedure for corrections

This is my first attempt at a BIAB. I am attempting a Yuengling clone. Please see reciepe from beersmith below. I have lots of uncertanty, let me lay out what equpment I have and how I understand the proceedure to go for a single infushion (not sure if I shoudl do a mash out yet).

I have a 20qt pot and a 10qt pot.

Step 1 add 5.63qt of water to 10qt pot with bag inside and heat to 163.7F.
Step 2 remove from heat and stir in all crushed grains 1lb crystal malt, 1.5lbs flaked corn, 2lbs 2 row
Step 3 cover and let sit for 60 minutes (probably cover with blanket to keep in heat....at this time I would fill my 20qt pot with 5 qts water and bring to 168f for later sparging
Step 4 remove bag and let drain for a few minutes
Step 5 add grain bag to sparge water for 10 minutes then drain.

After that I would add mash to sparge pot and proceed with extract and hop additions as normal.

This is using the Single infusion medium body mash profile in BeerSmith. The other option is the BIAB profile which changes the saccharification step to 13.32 quarts of water at 152.1 for 75 minutes instead. I guess I could do this in my larger pot then do the sparge in the smaller. Any suggestions on which route I should go or if I have any errors in my process or temps.

Last I have read about doing a protein rest to help clear up the beer. Is that something recommended to add to the process and if so do I choose the double infusion option in BeerSmith?

Looks good except the strike and sparge temps seams a little off. You will not have the temp drop as if you were adding strike water to a cold pot.
I would strike at around 160F for a target of 155F.
As for the sparge, I would drain and add water at around 174F for a target of 170F.

One tip for maintaining an even mash temp in the pot:

See if your brew pot will fit in your oven! My 20 qt does so I turn my oven on to 170F (the lowest setting) once it reaches that temp I turn it off and then put the mash in there once it reaches my target 152F. If your oven is 170F the air temp in the oven will easily drop to 150F when you open the oven to put the brew pot in and then just leave the oven off. Your mash temp will stay perfectly even!

I do have a large enough oven so I might try that.

Understood on the temperature corrections. Any comments on the single infushion method vs double infushion method?

Baby steps.
You can try multiple infusions next time.

I do this also. Over 75 BIAB batches later...

As for double infusion, imo its a waste of time. I have done lagers like this before with corn, no double required. If you want super clear.... time, irish moss, and such. BIAB lends itself to a bit more cloudyness, so maybe a double inf will help. But, i still say its a waste of time.

So I am also doing my first mini-biab and Beersmith is telling me to mash with 17.37 qts in my 20 qt pot. Now as this is my first time it seems like it would be easier to get the pot in and out of the oven with less volume. Is it at as easy as say filling the pot with 11.37 qts and mashing that at 60 min and then dunk sparge in the remaining 6 qts for ten minutes at 170 and then combined them for the boil? The grist to water ratio seems fine.

Also when it's in the oven, are you guys monitoring the temp or just set it and forget it? A lot of heat would be lost every time the oven gets open to check the temp, right?

As long as the mash ratio is ok, split up the water how you like. You'll need to adjust the strike temperatures to account for that. You could also tweak your mash profile to use your desired ratio and add multiple steps if you want. Then BeerSmith will agree with your actual mash, if you like that.

Opening the door will change the air temperature inside the stove very quickly, but it won't affect the temperature of your mash very much. It has a far, far greater thermal mass than the air.

thanks!

I plugged it in to beersmith and this is what I got.

6.30 lbs of grain into 11.5 qts of water. Strike temp is 165 to get a mash temp of 156. Rest for 60 in the oven.

Then dunk sparge for 10 minutes in 6 qts of water at 170.

Seems to make sense to me. Any thoughts on the stirke temp? Does it seem high or low to anyone?

Lastly, on the keeping in the oven, should I check the temp(and if so how often) or should I just let it be?

Those numbers seem generally ok. They're a bit different from usual practice, which would be to use a somewhat thicker mash and a larger quantity of sparge water, but it seems that BIAB brewers don't usually worry about that as much. I'd consider perhaps dropping to 9 or 10 quarts in the mash and adding the difference to the sparge. Not a big deal, though.

Temperatures seem reasonable, but whether they're accurate or not will depend on a lot of things (your room temperature, the thermal mass of your kettle, etc). I usually strike at around 170°F to hit 154-156 with around 6 pounds of grain.
