milling was done at the store when I bought the grains. I took the pre-boil G directly from the mash tun right before I started sparging. So is a pre-boil really needed for anything? Oh and should I toss the entire thing and try again or is there anything I can add it has only been 24 hours so far.
Taking your reading at that point would give a number more akin to first runnings. The sparging process would dilute things from that point.
I always take my pre-boil reading immediate after the hot break in the kettle. Not technically pre-boil but is worked me.
