I am contemplating brewing a 5 gallon batch which calls for a 21.25 lbs grain bill. If I did this I would be using a 48 qt cooler maash tun. Only problem is, the most grain I have ever used before is 10 lbs and that was BIAB. How do I determine how much strike water and sparge water to use for such a large grain bill? I know with BIAB, I usually use 1.25 qts per lb, but that comes out to be somewhere near 26.5 qts. Just seems like a whole lot of water for 5 gallons of wort. Additionally, to be more specific- how do you determine the amoutn of water for each the mash and then the sparge?
