Appreciate the input.

Between slowly doughing in, manually stirring during the raises, checking temps manually, & slowly lifting pounds of wet grain it's definitely a manual labor intensive brew day. But good to know I'm not necessarily killing my beer with O2 in the process. I should note that a more casual approach to BIAB led to higher figures on older brew days.

A couple other potential BIAB problem areas:

1) Wort Haze: I do have turbid wort going into the brew kettle but a long (and manual of course) whirlpool allows me to transfer fairly clear into fermentation. IIRC Nico stated that the big brewers sometimes transfer turbid wort into the Boil Kettle so I fear that less if so.

2) Lauter Stress: Stress caused during the bag lift concerns me. But as someone previously mentioned it's probably gentler than a mash filter. And maybe offset by the lack of pump stress.

I used 50ppm SMS and also used Brew Tan B (was planning on adding in AA but the LHBS didn't carry) so we'll see how it turns out.

Best is to mill straight into the MT if you can.

Can't you just drain the pot via a valve? That should avoid the lifting.

Turbidity of wort usually has a value of 50 EBC (source Narziss/Back).

Speaking of which, my 'update' to a trusted friend arrived today :D

I have fond memories of my first readings. I learned my first classic cold fermentation from this work.
