I am starting to think about a larger all grain system. Does anyone know how to size coolers as mash tuns? For example, if I want to make 20 gallon wort boils, how big off cooler should I get to mash the grain?
about half way down on this page is a good calulator. You just need to know how many pounds of grain you will have. http://www.rackers.org/calcs.shtml
Thanks a lot guys.. that really helps
