So I am in the middle of my first go at this recipe (and my first all grain recipe ever). I decided to do a double batch (possibly foolishly). But things seem to be working out nicely. I've got a 10 gal igloo cooler for a mash tun, so I had to do 2 mashes. The first runnings of the second mash are coming to an end here. Did the iodine starch conversion test on bath mashes and came out with flying colors, I haven't taken a gravity reading yet, but its good sweet wort.
Here is my dilemma: I have already pretty much filled my 18 gal boil pot without sparging the second mash. So, it's looking like I have 3 5-gal batches on my hands rather than 2. Do I need to triple the hop bill, rather than double it?
It seems dubious that I will get an answer in time to keep the show rolling, but any responses whenever would be greatly appreciated. (I am leaning towards, yes. Triple the volume, triple the hops. But its been done with only double the grain bill. So, I am slightly confused. Once, the first runnings have come to a stop, I'll take a gravity reading, and post that. Thanks again.
