We gather all of our sap from our farm's trees and from our neighbor's woodlot. We have a state of the art sap house that is wood-fired, uses reverse osmosis filtering for the sap and diatomaceous earth filtering for the syrup. We produce beautiful, sweet, golden maple syrup. We add nothing to our sap or syrup during the processing; it is simply the rich, delicious flavor of the sugar maple tree filtered for purity. Grade B Syrup is available in quarts, half gallons, and gallons.
