Mark asked about maple syrup:

Maple syrup is legal with 76 degree Brix (sugar density) in most states (varies slightly among state laws). Legal syrup boils at 7.3 or 7.5 degrees (state variation) above boiling water, which varies with the atmospheric air pressure. SO the better way to find the boiling temperature of syrup, in my opinion, is to use a barometer since the air pressure changes hourly.

A way to calculate the amount of sap needed to make a gallon of syrup is to divide 88 by the brix of the sap. Since sap sugar content (brix) may vary from 1.5% to 9.5%, there is a wide variation of the ratio. 2.2% sap gives 40:1 ratio of sap to syrup.
