Disclosed is a device for maple sap harvesting, which includes an assembly of a tubular sleeve which is removably mounted inside a tubular section of a tap. The tubular sleeve may be molded from a food-grade, anti-bacterial material. The tubular sleeve is inserted into the tap before the tap is driven into a maple tree. When the tap is removed from the tree at the conclusion of the sap harvest period, the sleeve may be discarded. The next season, a new sleeve is placed in the tap, with the new sleeve containing no residual bacterial contamination from the previous season of use.
