This is the second time this has happened to me. The first time a couple weeks ago I assumed I didn't get my 1st and 2nd running's stirred up well enough in my brew pot, so I let it go. Today I made sure to stir well, and i checked my gravity about every 15 minutes in the 60 minute boil. My pre boil today was 14.25 Brix, while my post came out to 12.75 brix. About every 15 minutes the reading dropped about .25 Brix. I use a refractometer so I'm fairly confident that the temperature of the wort isn't playing to much of a factor here. I measured around a gallon of boil off today, so I don't understand where these misreadings are coming from. The final OG is very close to what I expected it to be, so I guess all in all thats good.
The only thing I can come up with is that I'm brewing outside, and its about 25 degrees out today, would this mess with my refractometer? I do however come back inside the 65 degree house to double check these readings, and they don't change. I'm totally at a loss here.
