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.
For example, in a region where the boiling point of water is 98ÂºC (or 2ÂºC below normal), the cooking temperature of the sap must also be reduced by 2ÂºC (to 102ÂºC). There is, on average a 40:1 ratio when it comes to acquiring Maple Syrup. Around 40 litres (or gallons) of maple water must be evaporated to produce 1 litre (or gallon) of syrup. Most of the water (66%) in it evaporates during this process, leaving concentrated maple syrup.
