Rookie mistake, I know,and since I just started brewing in April, I guess I am still a rookie. This was batch 12 for me and it was one I just couldn't seem to get around to brewing. I started late on an Imperial IPA, ~15 lbs of grain mashed, fly sparked and in the kettle. Reached boil and add 1 oz Nugget and 1 oz Magnum. At 10pm, 25 min in, propane ran out. Too lat and too far away to get more, I let the batch cool uncovered for about 30 min, then covered leaving a gap for additional vapors to escape. I'll be starting back up this evening. My plan was to return to boil for ~45 minutes, completing the other hop additions. The original boil plan was for 60 min. Does this seem reasonable? Anything else I should do? Thanks!
