I just wanted some extra eyes on my math below, am I thinking about this correctly?
-Added 10.20 quarts of strike water to the mash tun, 6.05 pounds of grain.
-First runnings were 6 quarts.
-I calculated .10 gallons per pound of grain, which would be (.605 gallons) 2.42 quarts of water absorbed.
So if I had zero dead space I should have collected 7.78 quarts. I ended up collecting 6 quarts. I think I failed to account for the quart or so of dead space in my 10 gallon Rubbermaid MT.
Outside of that, I would still be .50 quarts off. Not a big deal at all, but curious if I should up the grain absorption rate next time, or is it dependent on the amount of grain?
