Hello,
I'm having an issue which is really doing my head in. I'm at breaking point.
My post boil SG is always 10points south of where it should be and I can't solve the problem.
Today I brewed 25L(into fermentor) batch. eff set at 68%
8.1kg malt mashed with 23L 67C water for 1hour. Mash pH was 5.2
10L near boiling water to lift to 74C.
I recirculated then ran to boil whilst fly sparging. Running to kettle took 1 hour.
15L of sparge water was used, 39L wort pre-boil at 1.050 (same as BS calculation) was collected, with and 3.5L left in the mash tun with an SG of 1.020 and pH 5.5.
I boiled for an hour and made hop additions throughout.
Whirlpooled and ran to my fermentor collecting a total of 25L with 5L trub and hop left in kettle (as expected. This volume has been entered into equipment set up also).
Boil off volume is set to 8L and shrinkage at 4% which is what must have happened as the fermentor volume is correct.
BUT post boil gravity is 1.055!!
Beersmith said it should be 1.066.
Its suggesting over an 8L boil off it should go from 1.050 to 1.066.....15 points!?!?!?!?
I'm 10 short!!
PLEASE HELP!
would be happy to upload BS recipe but unsure how.
PLEASE HELP
