Long story short, somehow after a chilling my beer after the boil, I've ended up with additional water in the wort (must have a leak in the chiller!).
Took me a while to notice, couldn't understand why my OG was 20points off!
As a result I need to boil the wort for another hour to get down to my intended volume.
What effect will this have on the beer? I guess I'll lose all of those hop aromas from late additions in the first boil?
For reference it's an APA with hop additions at 60, 15 & 0min.
I intend to do another hop stand to make up for this, but fully expecting the 2nd boil to have a detrimental effect on the beer...
