A sap collecting device for harvesting sap from a tree while minimizing damage to the tree. The sap collecting device includes a housing having a hollow interior volume, a first end, and a second end, wherein the first end includes an opening thereon. The first end can be placed flush against a portion of a tree having a small hole drilled therein. The housing is secured to the tree via a fastener that extends through the housing from the second end thereof. The first end further includes a gasket thereon for producing a fluid tight seal. A spout extends outward from the housing and includes an open end such that sap that flows into the housing can exit via the spout. The spout has one or more ridges on the exterior thereof so that a vacuum hose of a vacuum system can be connected to the spout.
