12 - 4 gallon batches... that's quite an undertaking. I think you're going to need some help in drinking all of those.
I agree that you should make a 13th combination of all of the hops. Maybe call it Rufus (for those of you not in the know, that's a reference to the movie Dogma). Or perhaps Matthias, the ACTUAL 13th apostle to replace Judas. Jesus is kind of an important dude too, maybe he could be the icon of the 13th beer.
And, not to start a heated debate based on another recent thread, maybe the 13th beer could be a direct blend of all the other 12.
