So my refractometer broke and I haven't had a chance to get a new one. So I was just going to fly blind and boil down to my final volume and see what I had for a fg but then I thought what about taking a sample just before putting the wort to boiling, chilling it down in the freezer, in this case it got to 55 deg and taking a hydrometer reading then. So that's what I did and came up with 1.050, my target is 1.054 but I forgot to stir the wort to mix it up and pulled most of my sample off the top half, so it's prob pretty close if this reading is accurate. So I guess that's my question, is this reading pretty accurate?
