I had a free day yesterday and got to spend it putting my new rig to work making my first BIAB batch. I'm getting my head wrapped around it, but as everyone knows there's a lot to process!
I used Brewer's Friend and because this is my first brew I had to go with some estimates on what my efficiency would be, thus the suggested starting volumes.
Recipe:
Brew Method: BIAB
Style Name: American IPA
Boil Time: 60 min
Batch Size: 5.5 gallons (fermentor volume)
Boil Size: 7.5 gallons
Boil Gravity: 1.036
Efficiency: 50% (brew house)
STATS:
Original Gravity: 1.049
Final Gravity: 1.011
ABV (standard): 4.88%
IBU (tinseth): 142.18
SRM (morey): 6.38
FERMENTABLES:
13 lb - American - Pale 2-Row (89.7%)
8 oz - American - White Wheat (3.4%)
8 oz - American - Carapils (Dextrine Malt) (3.4%)
8 oz - American - Caramel / Crystal 40L (3.4%)
HOPS:
2 oz - Magnum, Type: Pellet, AA: 15, Use: Boil for 60 min, IBU: 117.95
0.5 oz - Cascade, Type: Pellet, AA: 7, Use: Boil for 30 min, IBU: 10.58
1 oz - Cascade, Type: Pellet, AA: 7, Use: Aroma for 15 min, IBU: 13.66
0.5 oz - Cascade, Type: Pellet, AA: 7, Use: Dry Hop for 7 days
1 oz - Willamette, Type: Pellet, AA: 4.5, Use: Dry Hop for 7 days
YEAST:
White Labs - California Ale Yeast WLP001
Starter: No
Form: Liquid
Attenuation (avg): 76.5%
Flocculation: Medium
Optimum Temp: 68 - 73 F
Fermentation Temp: 70 F
Steps:
Brewer's friend tells me I have a conversion efficiency of 69.1%, pre-boil efficiency of 64%, Kettle efficiency of 59% and Brew House efficiency of 49%. This is the part I'm not clear on in regards to these numbers. Do they sound right? Are they good or bad, can I do something differently in the future? How will they affect this batch of beer?
Any comments or insight are greatly appreciated.

Starter: No
Form: Liquid
Attenuation (avg): 76.5%
Flocculation: Medium
Optimum Temp: 68 - 73 F
Fermentation Temp: 70 F
Steps:
- Heated 8.94 gallons of water to 154
- Lined kettle with bag, added grains and stirred
- Covered and monitored temp which quickly fell to 144
- Filled a pot with pre-wort from the kettle valve and brought to 200 degrees on a separate burner, added back to kettle which raised temp to 152, where it held fairly steady over the next hour, eventually falling to 148 at the end of the 60 minutes.
- Stirred grains every 15 minutes
- After an hour, removed grain bag and let it drain back into kettle, helped along with some squeezing of the bag to force more wort out.
- At this point I've got 8 gallons of wort with a gravity of 1.043
- Brought wort to a boil, added hops to a bag and started 60 minute timer
- Added hops to same bag at 30 minutes
- Added hops to same bag at 15 minutes
- Added wort chiller at 10 minutes, temp fell to 200 for a few minutes, then resumed boiling
- At this point I had a slight boilover and had to reduce the output of the burner
- Added 1 whirlfloc tab at 5 minutes
- Flameout at 0 minutes
- Connected wort chiller to water source and began chilling
- Connected pump to recirculator
- Removed hops bag and squeezed some of the wort out
- Chilled wort down to 70 in about 10-15 minutes (didn't time this step)
- Removed chiller
- At this point I've got 6 gallons of wort with a gravity of 1.053
- Transferred cooled wort to clean and sterile 6.5gal carboy
- Pumped oxygen for five minutes into carboy
- Gave the carboy a shake for good measure
- Added Yeast
- One more good luck shake to get some of the yeast off the sides of the carboy
- Filled 3 piece plastic airlock with star-san solution and stuck into the stopper on the carboy
- Carboy in shady corner of garage with a pretty stable temp of about 70
- Checked this morning and there is vigorous activity
