Hi All,
Can you please tell me if this is correct for an AG brew...
In a perfect brew setup, you would mash the grain, and the total of your first and second runnings would be the correct pre-boil amount, including the amount of evaporation lost during the boil.
Then at the end of the boil, you would have the correct amount for your fermenter.
I know its not that easy, but is that what we are chasing with efficiency / water volumes etc, or are we supposed to be aiming at a specific pre-boil gravity, more than a preset volume ?
Also, what is the simple explanation, of how I measure my mash efficiency ?
Sorry if this is a wierd question, its just that I dunno if I'm supposed to strive for the correct pre-boil volume, or a correct pre-boil; gravity, but please dont bl00dy tell me its both
cheers,
Chris...
