I missed my target OG by a mile! Partly due to the fact that it was a 11 gallon batch that eventually split into a 5 gallon Irish Red and American Amber. The difference between the two is the yeast in the primary.
My boil volume was a bit high, and I ended up with a gallon of excess that would not fit in my carboys. That contributed to my low gravity, had I boiled off a little extra, I might have gotten a higher OG. |
