Treleaven Wines | 73 followers on LinkedIn. A family owned winery since 1988 located on the eastern shore of Cayuga Lake. | Treleaven is built on two complementary visions. First, our founders Pete and Tacie Saltonstall wanted to start a winery inspired by the Burgundian ideal of a small family domaine that handles all the growing and producing of its own wines. A soup to nuts approach that lets us consider and control each part and process that our vines, grapes, and wines go through.
