Thanks Adamt
she's still on a roll boil and the SG is 1.071 and is approx 9 Lt volume
I'm only doing a small batch to fit in a 9Lt keg and my pot is 12 Lt, so started with 10 Lt and not sure how to calculate water addition..so it's not a volume issue it's a SG issue .....if that make any sense at all :huh:
I just don't want to add a little water into fermenter and test them add more and test, sort of hit and miss :unsure:
