Sap yield is usually expressed in terms of the number of tapholes, rather than the number of trees. The average yield for a taphole is from five to 15 gallons. However, under favorable conditions, a single taphole can produce as much as 40 to 80 gallons of sap in a single year. It takes about 10 gallons of sap to produce one quart of syrup.https://extension.umaine.edu/publications/wp-content/uploads/sites/52/2025/02/maple-bucket_web.jpg500667
