GENERAL MAPLE INFO
Sugar content of syrup = 66.9% (36Bº @ 60ºF)
1 gallon maple syrup = 7.5lbs maple sugar
Canning temp = 180–190ºF
Use only hot water to clean filters
Jones Rule: 86 ÷ sap sugar content = # of gallons of sap to make 1 gallon syrup
50 calories per tablespoon (corn syrup is 60 calories)
Maple granulated sugar can be used 1:1 ratio for white or brown sugar in recipes; is shelf stable
water weighs 8.35 lbs per gallon -> syrup weighs 11 lbs per gallon
1 gallon = 3.79 liters | 1 gallon = 231 cubic inches | 7.48 gallons = 1 cubic foot
ºF = (1.8 x ºC) + 32 — note: x “9/5” = 1.8
ºC = (ºF – 32 ) ÷ 1.8 — note: instead of “x 5/9″ like we learned in school, dividing ÷ 1.8 works, too!
water 1 foot deep = 0.8826in of mercury | 1’ deep of water = 0.4335psi
