I'm doing a 1 gallon pale ale tonight, with a really simple all grain bill. I started my timer for the boil, and when it rang, I thought, that didn't feel like 30 minutes. I added my 30 min hops and cranked the timer back to 30 more minutes. Left the room and came back, and the timer was down to 15 minutes! It took about 5 minutes to run down from 30.
I am guessing from my glances at the clock that it was really only about 15 minutes when the timer went off the first time. That's just a guess. So...
I fished out the flavor hops (in a sack) and set the microwave timer for 15 min. I'll add the hops back in at what I believe may be about 30 minutes into the boil. I suspect it might be a little higher in bitterness because of the 5 minute in-and-out hop addition, but I hope there will still be enough flavor left on those hops, too.
Argh!!
