Maple sap as it comes from the tree is 98% water and 2% sugar and minerals. Maple syrup is 76% sugar and minerals. 42 gallons of water must be removed from the sap to make one gallon of syrup. The water is usually removed by boiling the sap until only the syrup remains. All that boiling takes lots of energy. The standard maple syrup evaporator needs 451,150 BTU or 3.25 gallons of fuel oil to make one gallon of syrup. Our Sugarhouse We use a high efficiency firewood gasification evaporator and a reverse osmosis process to make our maple syrup. Reverse osmosis is a filtration process where most of the sugar and minerals are separated from the water in the sap. The concentrated sap is then boiled into syrup on the high efficiency firewood gasification evaporator. Energy consumption is dramatically reduced to the point where in our sugarhouse we use only 58,882 BTU or the firewood equivalent of .13 gallons of fuel oil to make one gallon of syrup. The firewood is sustainably harvested from our maple orchard and the electricity for the reverse osmosis machine is made here by harvesting wind and solar power.
