I've done the below recipe as an Extract plus specialty grains 3 times now and it is fantastic. Now I want to try it as BIAB recipe, but I'm not sure I'm doing the conversions, etc. right. Also it is my first BIAB, so I'm documenting the details of what I understand the process to be below:
===Extract Recipe (5 gallon) ===
Extracts
4 lbs Pilsen LME
2 lbs Wheat LME
Grains:
10oz White Wheat
8 Oz Munich
6 Oz Honeymalt
1 lb Oats
Boil:
60 min 1 oz Hallertau Hops
15 min 1/2 Tablespoon Cinnimmon
15 min 2 teaspoons Nutmeg
15 min 1/2 oz bitter orange peel
5 min 1/2 oz Hallertau Hops
2 min 1/2 oz Hallertau Hops
I'm trying to use the BIABacus 1.3 beer calculator spreadsheet to assist in converting it to a BIAB recipe. It gives estimated water loss volumes for each stage and tells you how much you need. I'm only using a 7.5 gallon kettle, so I'm reserving 1 gallon of water to add during the boil as evaporation reduces the volume. BIABacus allows that option, so I assume it's a reasonable thing to do.
===============
BIAB no-sparge recipe (5 gallon batch using a paint strainer bag for the BIAB bag), also adding one gallon during boil due to limited kettle size
heat 6.5 gallons water to 152 degrees (strike temp),
add grains
Pilsen Malted Barley - 5.36 lbs
wheat - 2.68 lbs
flaked white wheat - 10 oz
munich - 8 oz
honeymalt - 6 oz
Oats - 1 lb
(Are the "wheat" and the "flaked white wheat" the same kinds of wheat. Do I just need to add the weights together and buy flaked white wheat?)
(Should the specialty grains be held out of the mash for now and added with 30 minutes to go?)
Remove heat and let mash for 60 minutes, hopefully temps don't drop more than a couple degrees. Add minimal heat via burner if required.
Lift paint strainer and let grains drain
re-light burner and bring remaining 5.8 gallons to boil (0.7 gallons absorbed by grains)
(I assume I can relight the burner immediately after lifting the bag and before I start the sparge / drip drain)
Since I'm using Pilsen grain and BIAB is a all-grain process, I assume I need a 90 minute boil? I will be adding the 1 gallon of reserved water slowly during the 90 minute boil.
90 min - boil (for all-grain with a pilsen grain)
Time left in Boil:
End of boil volume - 6.1 gallons
20 min - cool (using an immersion cooling coil for the first time)
Ambient volume - 5.85 gallons
pour into fermenter / verify OG / add yeast / put away for fermenting
Kettle to fermenter loss - 0.85 gallons
volume in fermenter
===
Any thoughts, feedback, corrections very welcome. In addition to overall concern I have the BIAB recipe properly laid out, I'm very confused by the kettle to fermenter loss of 0.85 gallons. I typically pour everything in the kettle into the fermenter, so I have no loss on that step.
What am I supposed to be doing on that transfer that would cause a 0.85 gallon loss?
Thanks
Greg
