I've been researching for my own recipe on an Oatmeal Stout. It's just about ready for brewing, but I have a question on the mashing water volume. I've seen that I should add 1.25 quarts for every pound of grain. Here are the grains I'm using:
English Maris Otter
I am also using 1 pound of flaked oats in the mash - should I be counting that as a specialty grain and adding an additional 1.25 quarts to the mash volume?
Also, is it true you should sparge with the same amount of water as the mashing volume (so if I mash with 5 quarts, I need to sparge with 5 quarts)
