William Heritage Winery hosts corporate gatherings, birthday celebrations, bridal showers and other private occasions, from a group of 30 to more than 200 guests. Events take place at the estate tasting room in Mullica Hill, in Harrison Township, New Jersey, or at the smaller tasting room in Haddonfield.
Seminars and company events
The winery names corporate gatherings among the private events it books. The format is a social one: a team outing, a client thank-you, or an end-of-year party with wine poured from the winery's own range. At Mullica Hill a semi-private indoor seating area takes up to 40 guests, which suits a department lunch or a small celebration. Larger groups move outside, where a roped-off private area holds 200 guests or more and can include a private pavilion wine bar. Smaller outdoor sections are reserved for groups of 30 or more. The Haddonfield tasting room offers a semi-private indoor area for up to 30, a practical choice for teams based closer to Philadelphia. The winery does not describe meeting equipment such as screens or microphones, so it fits gatherings and celebrations more than working seminars.
Rooms and capacities
At Mullica Hill: a semi-private indoor seating area for up to 40 guests, a roped-off outdoor private area for 200 or more, smaller outdoor sections for groups of 30 or more, and an outdoor pavilion wine bar that can be added to the larger area. At Haddonfield: a semi-private indoor area for up to 30 guests. The outdoor area at Mullica Hill is the largest space the winery lists, and the indoor areas are semi-private rather than closed rooms.
Catering
Hosts may bring their own food or work with one of the winery's preferred vendors, which keeps the menu flexible, from a simple buffet to a catered meal. Wine is bought separately from the rental, and outside alcohol is not allowed. Private events are aimed at adults. Guests under 21 may attend with an adult at all times, but the winery does not host children's parties.
History and setting
The Heritage family has farmed this land for six generations, starting in 1853. Earlier generations grew apples and peaches. In 2001 William (Bill) Heritage and his wife, Penni, founded Heritage Vineyards and Winery, and the estate now grows grapes for wine on its 150 acres. The range covers red, white and rosé wines, along with a line of Jersey wines. Mullica Hill lies in the farmland of South Jersey, and the vineyard setting gives outdoor events a rural backdrop within reach of the Philadelphia area. The winery also runs a public events calendar, so organizers should check that their date does not clash with a busy public weekend.
Getting there
The estate is at 480 Mullica Hill Road, Mullica Hill, NJ 08062. The second tasting room is at 127 Kings Highway East, Haddonfield, NJ 08033. Philadelphia International Airport is the nearest major airport. Most guests arrive by car, so plan parking and designated drivers for an event where wine is served.
