To make the Maple Syrup you need to boil the sap to remove the water and skim the impuities that float to the top. It also takes A LOT of sap to make a small amount of syrup. A Smoker may not be very practical to get the job done. Check this out from the University of Vermont...JJ
How many gallons of sap does it take to make maple syrup?
Using the “Rule of 86,” you can figure that the number of gallons of sap you need to produce one gallon of syrup is equal to 86 gallons divided by the percent of sugar. So if you start with sap that is 2% sugar, you would need to evaporate 43 gallons to water (86 gallons / 2% = 43 gallons) to make one gallon of syrup.
How much maple syrup does one tree produce?
The volume of sap produced during a single season can vary anywhere from 10 to 20 gallons of sap, or 1/3 of a gallon of maple syrup. The volume depends on the tree, weather conditions, length of the sap season, and the method for collecting sap – producers using gravity lines or buckets generally get 10-14 gallons of sap per tree, while producers using vacuum tubing generally get 15-20 gallons of sap per tree.
