Sorry for resurrecting an old thread, but I'm getting ready to do a porter, and this one looks promising!
However, I had a question about the boil time. It's been mentioned that this is a 90 minute boil - no problem, I can do that. But out of curiosity: why 90 minutes?
I assume the 90 minute boil is determined by the hops additions? Won't you get the same bitterness amounts (and no flavor or aroma) from the first two additions? If that's the case, why not add both the Northern Brewer and Fuggles at the same time, and cut the boil time by 30 minutes?
Is the prolonged boil intended to boil off a certain amount of water? If so, what (pre-boil) starting volume should I aim for? (Should I just figure out how much I boil off per hour, and plan for 5.25 gallons + trub loss + boil loss?)
Thanks!
