Screwed up my volumes for a mild and I ended up with too much wort that is a bit too weak. I should have taken a gravity before I put it into the carboy but I didn’t. Lesson learned.
Now I have about 5 L of wort with hops in it. Can this be kept and used for starter? I’d re-boil it after freezing anyway but it seems a waste to pitch it if it can be used. OG is 1.034
Yeah, you can definitely use it for a starter.
After every batch, I strain the leftover wort, dilute to 1.03x’ish and pressure can it for use in subsequent starters. Since it’s always made from leftover wort, there’s always hops present. No problems.
