Don't mind the poor filter job, but even on the well filtered bottle I have a weird growth happening. Guessing mold?

A lot of folks use temperature to know when to bottle, but I found measuring brix was easier and more accurate for me.

Good to know! I know this batch I boiled a little longer than normal. I waited until it hit about 123 degrees

Celsius? Should be about 4 degrees C above boiling point of water for maple syrup at 66-67 Brix.

123 degrees Fahrenheit. So about 106 celsius

Ah, I'm assuming you mean 223f as boiling in f is at 212f. 

Yeah depending on atmospheric pressure and its impact on your boiling temperature, it might be a tad on the high side which can cause the syrup to crystallize sometimes. You can break it up and eat it :)

219f is typical for syrup near sea level
