Predicting SRM
Posted: Wed Feb 25, 2009 11:35 pm
I applied standard calculations to predict SRM for a Strong Dark Belgian I'm brewing. I got the following SRMs per pound for each of the grains I used:
Carapils: 1.55L
Special B: 180L
Pilsner LME:2.25L
Dark Candi Sugar: 275L
Soft Brown Sugar:60L
I steeped the Carapils and Special B. I added the LME and sugar end of boil.
Multiplying each value per pounds used and adding the values, I got a total of 723...then divided by 5 gallons to get the MCU:
I got MCU= 723/5=144.6
And SRM= 1.4922 *(MCU^^0.6859)
SRM= 1.4922 * 144.6^^0.6859
SO,
SRM=47 ?????
But the color of my my beer is closer to 20 SRM. So, what am I missing?
Thanks for your thoughts.
