All tours complement classroom and homeschool programs by enhancing learning in social studies, environmental science, New Jersey history, and other related subjects. They also align with many of the New Jersey Core Curriculum Content Standards.
Terhune produces wine from Cabernet Franc, Cabernet Sauvignon, Chambourcin, Chardonnay, Niagara, Orange Muscat, Traminette, and Vidal blanc grapes. Terhune also makes fruit wines from apples, blueberries, and peaches. Additionally, the farm produces and sells bread, cider, doughnuts, flowers, fruits, herbs, pies, and vegetables. It is the only winery in New Jersey that produces wine from Orange Muscat, which is a white vinifera grape of unknown origin that is often used to make dessert wines. Terhune is not located in one of New Jersey's three viticultural areas.
During the autumn harvest season, the winery offers apple picking and wagon rides. Terhune has a plenary winery license from the New Jersey Division of Alcoholic Beverage Control, which allows it to produce an unrestricted amount of wine, operate up to 15 off-premises sales rooms, and ship up to 12 cases per year to consumers in-state or out-of-state. The winery is a member of the Garden State Wine Growers Association and its subsidiary, Vintage North Jersey.
