Going for my first AG/BIAB today. Split my mash into two kettles, my old five gal and my eight gal boil kettle. Went with my SNPA Clone, the one discussed extensively on the Recipe forum, as I can find fresh SNPA for comparison, and my extract clones were pretty successful. I managed to make wort, and have the SG samples from each kettle, as well as the total wort, cooling down in the fridge so I can take hydro samples to find my pre-boil OG.
My only failure, was that I didn’t take one obvious factor into consideration, which is the amount of water the grain would absorb. Basically, I used 6 gals for a five gallon batch. This is my standard amount for ex/grain and it always landed my with 5 gals of beer after boil off. Now, I have 5 gals of wort, so I;m obviously going to be boiling this brew down and will likely end up with less beer and a higher OG then SNPA. Don’t have anymore bottled water, and my local water is gross so I’m just going with this brew. Unsure if I’m going to adjust hop additions or anything like that, or if I’ll just have the IBUs ramped up to a more IPA level. We’ll see how it goes, but overall I think this was a success, would just up the water by a gallon next time around. I’ll post an update with the pre-boil SG’s later to see what kind of efficiency I got.
