I brewed my second batch of beer yesterday and for the second time seem to be getting an OG reading that doesn't seem correct. The first batch, I took the reading by pouring a small amount out of the carboy immediately after the wort and H2O were in. The second batch, I took my reading the same was but poured my H2O in before the wort to get a better mixture, thinking this might have been the cause of my first "off" reading. Didn't seem to make a difference. My reading on my wheat beer was 1.020. That seems low to me. Does anyone have advice for a beginner on how to get an accurate OG and even on how to get accurate readings from the carboy down the road?
