Pure Maple Syrup

Sugar Maple Trees

Sugar Maple Trees

We tap the sap from maple trees on the edge of our orchards and roads.  These trees have direct sunlight and large canopies and are over 100 years old.

Efficiency

Sugar Maple Trees

To reduce the amount of energy required to convert sap to syrup (40 gallons of sap is needed to make a gallon of syrup), we use a home constructed reverse osmosis (RO) system to concentrate the sugar in the sap.

Sweet heat and humidity

After removing water from the sap using the RO, only 10 gallons of concentrated sap is needed to produce a gallon of syrup.  The wood stove that heats our home can accomplish the evaporation - providing heat and humidity and a touch of sweetness.

2025 Syrup Available

Chestnut and Pure Maple Syrup are perfect together!  We are keep our operation small and sustainable. Therefore, we only have about  5 gallons of syrup left from 2025.  Order your syrup with your chestnuts and we will ship them together!
