Abstract. Yields of sugar maple sap collected from three plastic pipeline systems by gravity, vacuum pump, and a vacuum pump with a transfer tank were compared during 2 years in northern Vermont.The transfer system yielded 27 percent more sap one year and 17 percent more the next year.Higher vacuum levels at the tapholes were observed in the transfer system.he transfer system yielded 27 percent more sap one year and 17 percent more the next year. Higher vacuum levels at the tapholes were observed in the transfer system.
Donât make the mistake of thinking you can tap now and process later â this will affect the taste and chemical properties of the Birch sap. Birch syrup on the other hand has a shelf life of around two years â but it takes about 130 â 150 gallons sap make to make one gallon syrup. (Source).
