I am trying to move to hydrometer readings to verify that my brew is done instead the "it's been more than three weeks so it's time to bottle" method. I have seen posts that say wait until you get the same reading three days in a row, or until you are with in a few points of your expected final gravity. My question is this, what counts as a few points? If you don't reach your expected Original gravity, how do you compinsate for that in your final? The batch I have going now was supossed to have a OG of 1.065, when I added my top off water (I'm brewing extract with specialty grains) and took a reading I only hit1.054. Expexted FG was 1.010 and today I was at 1.017. I am obviosly kinda new at this and looking for some help. Any that you can offer would be greatly appreciated. Thanks.
