So, I'm brewing with a friend the other day. We both brewed the same recipe. We used some suspect malt that was given to us (I figured it was old as I came up short a few points whenever I used this stuff) Anyway, wort into the kettle and we were both 4 OG points low. I added some hot water and just sparged some more then boiled down the wort for about 45 minutes and got to my desired OG, then began my hops additions and timing my 60 min. boil. When I had finished boiling and started chilling, my friend was still boiling and I remarked about how I got ahead of him when he started first. He informed me that he was concentrating his wort to bring up the gravity. The thing is, he had already done all his hopping. Now, he did pull his hops before doing this boil, but my question is, what happens to all those late addition hops that were added for flavor and aroma? Obviously concentrating the wort is also going to concentrate the bitterness, but by continuing to boil, even after pulling the actual hops, wouldn't you continue to isomerize the hop oils even though the actual hops were not in there?
I haven't tasted the beer yet, it's still fermenting, but I'm expecting it to be pretty bitter.
