Seems like a simple question, but brewing my first AG batch and using an aeration stone for the first time left me a few problems.
So after sparging, I'm left with ~160*F water. I've seen hydrometer correction tables go to 150, but usually nothing over that. Is there an equation you can use?
And after pouring my cooled wort into my primary, I'm left with about an inch of foam on top that can't be scooped away to be able to see my hydrometer. Aeration makes it even worse. What do you do to get around this?
I'm not incredibly concerned about my hydrometer readings, it would just be nice to get a good baseline brewhouse efficiency for future reference.
