Maple syrup boils at 7.1 degrees Fahrenheit above the boiling temperature of water, so a good thermometer can be used to determine when it's syrup and and the density can be measured. Â°Bx Degrees Brix (symbol Â°Bx) is the sugar content of an aqueous solution.
Three species of maple trees are predominantly used to produce maple syrup: the sugar maple (Acer saccharum) , the black maple (A. nigrum) , and the red maple (A. rubrum) , because of the high sugar content (roughly two to five percent) in the sap of these species.aple syrup is a syrup usually made from the xylem sap of sugar maple, red maple, or black maple trees, although it can also be made from other maple species.
