I put this in another thread, but it wasn't getting any action, so I'm starting anew.
I brewed a barleywine last night that came out to 1.124, but only about 4 gallons of wort (with a layer of trub on the bottom). I've already pitched and fermentation looks strong and healthy.
That OG is way higher than what I wanted, and volume is about a gallon and 1/2 shy. So the question is, is it too late to top up with a gallon and 1/2 of boiled and cooled water? I know all my readings will be off, but I just want more volume at a lower OG.
Thanks in advance!
