Color way off, what's the reason?
I made my first attempt at a Belgian-style Dubbel the other day, creating the following recipe from the stuff I had at hand (didn't have any candi sugar, so I know it's not perfect) for 4.5 gallons:
51% 4 10 Belgian Two-row Pale
33% 3 0 Briess DME Golden Light
5% 0 8 Weyermann CaraRed
5% 0 8 Weyermann CaraPils
4% 0 6 Weyermann CaraAroma
1% 0 2 Chocolate Malt
60 mins 0.5 Northern Brewer
30 mins 0.4 Styrian Goldings
10 mins 0.5 Styrian Goldings
Safbrew S-33 yeast
OG and FG were in line with what was expected. However according to the calculations, SRM should be around 15-16. In reality, it's only around 9, so it seems I have made a Belgian Pale Ale instead.
What could be the cause of this? I mashed all malts together for 60 minutes at 149F, so that can't really be the problem?
What could cause such a big difference in SRM?
