I have read books on whiskey making, beer making, and searched the internet. They all talk about SG, BG, FG, etc. and I half way understand the gravity concept. However, I feel like a complete moron because I can not understand how to read the thing. I filled up the little plastic testtube looking thing (forget what its called) to 100 with spring water. Then I put in the hydrometer. After spilling some overflow onto the counter the water level was at the top of the plastic testube thingy and the hydrometer was floating where the water level was at 1.000 (all the way at the top). So after all this verboseness...how do I actually read this thing. KISS English only please.
