Well I just brewed my 1st all grain and after I took a sg reading of my wort which was 1.059 for 7.5 gallons...my hydrometer broke before I could check sg post boil, so can someone tell me if sg changes after the boil?According to my recipe my o.g should be 1.070.This was a 5 gallon batch w/ 14 lbs of grain.I ended up with 5 gallons after the boil , but I would like to figure my abv, and efficiency...should I just use me preboil sg reading?
