Frozen sap testing

[c0ps]

So I started with a frozen bucket of sap at 2.5 percent. I emptied 1 liter of Unfrozen sap and tested the sugar at 5 percent with a fractometer. I placed the frozen sap on my evaporator and kept testing the liquid as it melted. Here are my tests

1/4 melted tested at 3 percent
1/2 melted tested at 2 percent
3/4 melted tested at 1.5 percent
Last test before melt down tested at 1.2 percent

You know what, this is an extremely interesting test. Instead of RO, could one just determine a temperature and time correlation that the water would freeze at, and chuck that cube.

Yup. It's called a "poor mans ro"
