So I have a brew that appears to be finishing higher than expected, so I wanted to calibrate my hydrometer first to make sure that that's not the problem.
My question is when looking at the water line, there appears to be two different ways to read it. In 60* water, when looking at where the water line is flat and then looking at the hydrometer, it could be as much as .004 off. However, if I look at the water line at eye level, where the hydrometer touches the water, there's a little "hill" of water that comes up above the water line... like the hydrometer is drawing up a little bit of water right around it's edges. If I look at this line, the hydrometer is reading perfectly, or maybe .001 off, so there's potentially .004 difference between these two lines.
Does that description make sense? Which should I go by?
