So I'm close to starting my first AG, I have one last question. When accounting for lower efficiency by adding more grain (I set my efficiency level to 60% in promash, which people seem to recommend for your first AG), do you:
a) Add the necessary amount of extra water?
b) Add the same amount of water, but at a higher temperature due to the thermal mass added by the extra grains?
I'm leaning towards b.
Oh, this is probably obvious, but I'm batch sparging.
