Finally ordered a BIAB to use with my 15G kettle.
1) I have a 15G kettle and I still plan to make double batches. In-fact, making double batches is a must for me because it takes roughly the same time. According to an online calculator, 34lbs of grain will take up ~13.35G of volume given that you're having 1.25 quarts of water per pound of grain. It seems that I would be tight (still enough room to stir), but should be doable.
Basically, I won't be able to do my pre-boil amount with BIAB method. I'll have to lower it, but I'm assuming that 1.25 quarts of water per lb of grain would still lead to great efficiency. For 34lbs of grain, this would mean mashing with 10.6 gallons (maybe even a little bit more).
It seems that the calculator is placing 34lbs of grain to take up ABOUT 3 gallons of space.
My usual pre-boil is 12 gallons or so (2x 5 gallon carboys filled all the way up). If I did my usual pre-boil, then I would be 15 gallons. No go.
2) Basic-ass mashing question. When I get my mash temp stabilized, I cover it (I don't insulate it), and walk away for 30 minutes (or R.H.A.H.B). After 30 minutes, I'll come by and check. Usually I see about a 2-4F difference, depending on weather conditions. From there, I reheat (low) and stir while constantly checking temperature to bring it back up to proper mash temp, then I cover, and let it finish for another 30 minutes, maybe even more. Is this a proper approach?
3) It's my understanding that you can grind up the grains even more with BIABing. When I've previously grained (muslin-sock partial mash method) I would grind enough to split the shell, but I wouldn't grind anymore to obliterate the grain. I've been reading that you can grind pretty aggressively (not so agressive that it turns it to 100% powder) but a nice agressive grind. Is this true?
That's basically all my BIAB questions. It looks pretty damn straight forward. Get water to proper strike temp, stick bag in, clip it in, poor in grain (slowly) while doing an "upward" motion mix. Then proceed to mashing. When mashing is over. raise up bag and and crank on the heat. Let it drain for 10 minutes or so. Squeeze the bag to get it all wort out. Splarge with a water hose if boil volume is low. Then continue to do everything I've always done.
