I seem to be having a problem. I fear it is the usual suspect, user error.
When sampling with my beer thief and placing the hydrometer in said thief, my gravity readings seem to be low. For example, with regular old water, and about 65 degrees, in a standard plastic tube thing, the OG reading is at or darn near 1.000, same water in the thief, and i read .008
This would explain why my OG is continuously low and the FG is as well - my ABV seems right on. Seems like I need to at 2-3 points to a reading out of the thief.
The physics professor in me (read: I have a business degree) says the the smaller diameter of the thief leads to higher surface tension and generally lower readings.
Yes, I'm doing my best to let the hydro not stick to the side, etc. Yes, I' reading from the top of the miniscus. Yes, my beer turns out pretty good. Yes, I should RDWHAHB. But, help me anyway!
