You know what I wonder but had never considered before? If the different grades of maple syrup make a difference? I mean, they’re all cooked to the same density and sugar content (more or less) but fancy grade/grade A is pulled from earlier sap that has higher initial sugar content then kitchen grade/grade B (personal favorite).
After a quick google it seems that there is no significant difference, even though the cooking times may vary they all end at the same point of buoyancy/density so essentially the same. Minerals are nutrients inherent in the syrup appear unaffected by the evaporation process, or by reverse osmosis (where water is pulled from the sap before boiling to shorten the boiling process, usually yields a greater quantity of grade A syrup, which typically is the most desired variety.) I find that hard to believe, I would think some of the micro-nutrients are removed through the osmosis filter but can’t say not knowing.
I’m just going to stick to Grade B and not worry about it too much. What I have learned is that any difference is likely nominal and within typical syrup variation.
