I live in Walla Walla, WA, where the wheat grows aplenty. I thought I might "acquire" some wheat from some local farms to throw in my first hefe batch. Give it some local flavor. What do I need to do to it to prepare it for a mash? It is pretty close to harvest time around here, so I am thinking I just cut a couple of pounds, mill it up a little bit and mash. Also, could I do the same thing with rye?
