Whoa- I look away for a second and lo! and behold, even more brewers sign in- a big welcome to all newcomers!
(Nb. I try not to delve into to much discussion here in this thread, but a little bit won't hurt now and then... Mods- feel free to relocate if you think it is warranted.)
thylacine, the Mini- and Maxi-BIAB
guides should interest you, might need a bigger fermenter for the latter though! When your registration is approved all of the images and downloads hosted here should become available.
DC_Bob, you should be pleased with the improvements All- Grain brewing can make, once you try it you'll know there's just no turning back. BIAB can be just a step in the process of migrating to AG or it can be the end, for me it is the end but not in a bad way.
No_Secondary (what a gr8 nick!), there's a couple of ways of doing that:
a) Passive lagging: Overheat the strike water by 5-10C, place lagging/ insulation (lots of it where you are), allow to cool to strike temp, add grain, stir and re- cover. Pre- heating everything equates to less heat loss during the mash. Importantly, just leave it be, I wouldn't regularly lift the insulation off to check the temp, stir etc, it will just lose even more heat and gains nothing but pain. I would check it after 15 minutes though and adjust if need be with extra infusion, but other than that just leave it to do its enzyme thing.
b) Direct- heating during the mash: A cake rack or upturned colander covering the base of the kettle to keep the material away from the hot base. You must stir the added heat quite thoroughly and it tends to be unevenly distributed.
I much prefer option a). It is probably nothing compared to yours in NJ, but here in the winter by pre- heating and using loads of insulation I can repeatedly limit the heat losses to around 1C during a 90 minute and longer mash, quite a feat of thermodynamics IMO!
