I measured my starter SG using the leftovers in the boil kettle and it measured 14.2 Brix. This was when in an ice bath, so maybe at best it was a bit cold. I'm making a 2L starter and according to the calculator online, my SG is at 1.057. Should I add sanitized water to correct?
FYI, I'm boiling 3 cups water now and will measure and add accordingly... I have a 5 gallon bucket of starsan to sanitize while I go.
