I ended up making this, my first all-grain (BIAB) on Sunday.
Managed to find all the ingredients needed, scaled the recipe to 3.5 gallons in Beersmith, and I think it went great!
I hit all the gravity and volume's pretty much spot on, and as of yesterday (about a day after pitching) it was bubbling away like crazy, and still doing so this morning.
Only hiccup on brew-day was in the mash... I'd planned on putting the kettle in the oven to help hold the temperature, but I was doing it at a friends place and realized his oven was too small.
So I just kept it on the stove top, and monitored, turned the heat on a bit and stirred a few times when I saw the temp drop more than a couple degrees.
Near the end of the mash I overshot the heat and got up to 160 (mashing at 152)
Fortunately (I think), this was with about 15 minutes left in the mash, so likely most, if not all, of the conversion was already done.
Other than that, all went well.
I'm not sure it'll be as dark as some of the pic's in this thread. As I was pouring from the kettle into the bucket, the beer looked more pale. Hard to tell for sure though.
I also made the decision to just dump everything, cold break and all, into the bucket. Not sure if that was a good plan or not. I've done that before with my extract batches, but the cold break on this all-grain was incredible, and now I'm hoping that it compacts down decently so I'm not cursing it when the time comes to rack to the bottling bucket.
I've got it fermenting in my fermentation cooler bag. The bucket went in the bag at 71F, dropped to 61F overnight, and as of this morning, with the vigorous fermentation, it was sitting at 64.
Plan to try to keep it around 64-65 through the next 3 or 4 days, assuming the bulk of fermentation will be done by then, then probably try to let it rise to high 60's until it measures as being done.
Then into the bottles to condition!
I'm looking forward to tasting this in a month or so.
