Last sunday I brewed a chocolate porter and missed my OG....It was supposed to be between 1.044 and 1.047 it ended up being 1.030.... how bad is it going to be?
+1 again on what he said. Unless you forgot to add something or added way too much water (which would overfill the bucket), your OG should be spot on despite what your hydrometer says.
Yeah, What they all said. If you used all the ingredients and ended up with the right volume, you will get the right gravity. It is common that the top up water will not mix fully so you might get a high or low reading depending on if the sample got more of the concentrated wort or if it got the more top up water.
