So I had a weird brew day yesterday. I was testing out a LOT of new equipment including a new propane regulator. Needless to say my burners now sound like jet engines. However in my boil pot i had 11 gallons to start the boil, and when I finished i had 5? Is this Possible???

That's pretty hard to believe, I gotta imagine that your measurements were off somehow. How long of a boil?

6 hours...

I would think removing over 50% of the water would leave you with syrup.

LOL! Yeah, I can definitely see a 6 gallon boil-off there...

It was 90 minutes, but It was getting pretty hot? The final product is pretty thick. Looks drinkable but pretty thick

Did you get a preboil and postboil reading? I think it would have at least doubled. Like 1.04-1.08. That boil must have been blazin.

Curious about that as well. I started with 7 gallons and was targeting 5.5 gallons after a 60 minute boil (converted keggle, 12" opening)). I ended up with 5 so know only about 4.8 gallons ended up in the fermentor. It was a beautiful day today at about 72. I turned down the burner so it was just at boiling.

What is the normal rate for boil off? Beersmith uses 25.1% an hour. Does that sound about standard for everyone?

I boil off about 1.3 gal/hr. I wouldn't use evaporation rate as a %.

I boil off about 1.5 gallons in a 15g keggle with a moderately strong boil. If I turn the burner to full output and get a crazy vigorous boil it's more like 2.2 gallons. Initial volume doesn't matter.
