I think there's something up with the refractometer. I checked a sample from last years syrup in the refrigerator after bringing the sample up to room temp and it only read 58 brix, but I know it was 66.5 when I bottled it last year. It was checked, and double and tripple checked. But that doesn't explain the olive oil reading correctly now.

Also, I just filtered what I had and now it reads 64 brix. So I'm thinking that If my last years sample is correct but reading 58 now, and I have currently over boiled based on temp and it's reading 64, then my current sample is maybe really at 70ish brix. If that's the case, I can add some sap, boil to 219.5 and hope it's okay?
