I brewed an irish red ale last night and my preboil gravity was 1.042 and my O.G was 1.059. I kept the sample on the table and when I check it today its only a 1.030. The temps I checked at were 68 degrees both times. I thought maybe the sample just settled, so I mixed it all up and checked again and am still only getting a 1.030. The brew seemed to go well and I am leaning towards my drunken brew day readings more than the sober ones I took today. any Ideas what might be going on here?
