Is there any resource you all have access to that discusses the optimum grain to water ratios when creating the mash? I've seen lots of 'rules of thumb,' such as 1.5 lbs of grain to gallon of water, and some much higher than that. But it seems like because the amount of sugars available from say corn vs barley are different, we would have a different 'rule of thumb', for each grain...
Secondarily if my grain bill is 70% corn, 23% rye, 7% barley and I'm doing 100 gallon runs, how much total weight of grain is needed?
Thanks as always...
