Im planning on brewing an IPA and would like to use enough fresh ginger to compliment the grapefruit flavor of the Simcoe and Cascade hops I'll be using. It seems like every thread on here has inconsistent amounts to use so Im taking a poll. On a side note, after sparging I was wondering if I could sourmash and partigyle a sour with the second runnings, any thoughts, opinions, or advice? Heres the grain bill... 15# 2Row , .5 # C60.
