This is some very interesting information! I've been doing 60 minute boils the entire time I've homebrewed (and longer for big beers in particular to boil down).
Saving 30 minutes could be amazing for me. I just recently converted to electric, and I typically split my brewday. Once we come home from work, I spend ~40 minutes to mash in, go back upstairs with family, and then after the kids are in bed, I go back down for the rest, which is roughly around 2 hours. If I could cut that last part down to 1.5 hours, that could be pretty amazing.
The only thing is to convert my hop schedules to account for the shorter boil. For those of you doing 30 minute boils, are you utilizing software to do the calculations for you, or do you have a rule of thumb that you use to get the IBUs the same?
I've got so many pounds of hops in the freezer, that the time savings would easily be worth it.
