Hello all, did my first BIAB last night and I have some questions about an apparently high efficiency.
Jamil's Triple x Stout- Recipe cut in half for 3 gallon batch (didn't want to screw up 5 gallons on my first attempt.)
5lbs Marris Otter
.33lb Crystal 80
.25lb pale chocolate
.5lb black patent
.5lb lactose added at 45min
.75oz east kent goldings @ beginning of boil
Recipe calls for pre boil gravity of 1.051 and post boil of 1.060, efficiency of 70%
My procedure:
Strike water-4 gallons at 161*
Mash Temp- 152* for 70 min
water loss to grains-1 liter
Pre boil volume 3.75 gallons
Pre boil gravity 1.054 (wort was mixed and cooled, hydrometer is tested and accurate)
60min boil
Post boil gravity 1.070
post boil volume 3 gallons
I did a mash out for 10 min @168* while stirring then squeezed the crap outta that bag. The grains were Northern Brewer's standard crush.
If I calculate my efficiency using the Brewers Friend calculator it comes to 91% pre boil and 94% post boil, I realize that the lactose will bump the post boil gravity, but I came out 10 full points above what the recipe called for!
I decided not to dilute it and just have a higher alcohol stout.
So, my questions for all the BIAB folks out there-
Is this a fluke?
Did I figure something wrong?
How should I adjust my procedure to get closer to what the recipe calls for? Right now all I really want is to learn to brew consistently.
Thanks all, this forum is great!
