It seems I can't extract sugar out of those grains.
This is a short recap of my brew session today.
These are the ingredients used:
Ingredients:
------------
Amt Name Type # %/IBU Volume
2,50 kg Pale Malt, Maris Otter (5,9 EBC) Grain 1 100,0 % 1,63 L
15,00 g Citra [12,00 %] - Boil 60,0 min Hop 2 64,7 IBUs -
15,00 g Citra [12,00 %] - Boil 15,0 min Hop 3 32,1 IBUs -
10,00 g Citra [12,00 %] - Boil 5,0 min Hop 4 8,6 IBUs -
1,0 pkg Safale American (DCL/Fermentis #US-05) [50,28 m Yeast 5 - -
10,00 g Citra [12,00 %] - Dry Hop 14,0 Days Hop 6 0,0 IBUs -
The brewhouse efficiency is set to 72% in BeerSmith, yielding a potential 1081 SG.
I mashed the grains for 60 minutes at 68,9C and mashed ut for 10 minutes at 75,6C.
During the process, I stirred those grains really well several times; I was feeling like a pro.
The estimated pre-boil gravity was 1064 SG, but in reality, these were my readings:
130 SG @ 55C = (Adjusted for 20C) 131,6
135 SG @ 43,7C = (Adjusted for 20C) 136
142 SG @ 24C = (Adjusted for 20C) 142,1
After the boil the OG was 148 SG @ 23,5C = (Adjusted for 20C) 148,1
According to these numbers, the estimated ABV will be about 4,6%, far from the original estimated ABV of 8%.
Also, according to my calculations (Beersmith really), the brewhouse efficiency is 42%?
Grains seemed crushed well enough.
What could've gone wrong?
Thanks!
