5 gallon mash turned into 4 gallons after ferment

[shudson4099]

I have searched and searched and cannot find an answer but I must be missing this somewhere.

I’m seriously a newbie as this is my first cracked corn mash and approaching my first run. My fermenting is complete starting at 1.052 and ending at 1.000 which should be 6.825abv. I know that’s not great but it’s still my first try. I milled the crack corn to make it finer but not powder. I used 6lbs of corn to 5 gallons of water, so I don’t believe it used enough corn. Also, my heat was inconsistent but I have bought a new heat source to improve that and to hopefully make a more consistent spirit run.

So after fermentation I only have about 4 gallons of mash now. Weird to me, but maybe normal. I am thinking I should just run the four gallons as it is and see what happens, but my question is should I add any water to the mash? I think the answer is no, but, this is my absolute first run.

I have a copper pot still if that helps with the question at all.

I apologize for the novice question and am certainly ok with a redirect to some reading that would answer my question.
