maple tree is usually at least 45 years old and 12 inches
in diameter before it is tapped.
a tree increases in diameter, more taps can be added: up
to a maximum of three taps, usually two.
does no permanent damage to the tree and only about 10%
of the sap is collected each year.
tap yields an average of 10 gallons of sap per season: that
yields about one quart of syrup.
sunny days (above 40 degrees F) and frosty nights are ideal
for sap flow.
Maple season may last 4 to 6 weeks, but sap flow is heaviest
for 10 to 20 days.
flowing in high volumes is called a "run."
harvest season ends with the arrival of warm spring nights
and early bud development in the trees.
gallons of sap are evaporated to make one gallon of syrup.
syrup is boiled even further to produce Maple cream, sugar
takes one gallon of syrup to produce eight pounds of candy
gallon of pure Maple syrup weighs 11 pounds.
sugar content of sap averages 2.5%, of syrup 66.5%
