Rosehall Run Winery, one of the earliest Prince Edward County wineries, is nestled in the west central region known as Hillier Ward. Founded in 2000 by Dan and Lynn Sullivan, with support from Cam Reston, Rosehall Run has always been a working farm, accommodating the needs of an efficient grape growing farm and a winemaking operation. Situated on a 150-acre farm, Rosehall Run benefits from its close proximity to Lake Ontario and the exceptional clay soil scattered with rock and shale fragments on a calcareous limestone base.

The vineyard, which started in 2001 with Pinot Noir and Chardonnay, now spans 25 acres and includes varietals such as Pinot Gris, Sauvignon Blanc, Gewurztraminer, Muscat, and Tempranillo. To support their commitment to state-of-the-art winemaking, Rosehall Run constructed a 7,200 sq ft winery facility and barrel cellar, showcasing their dedication to quality and craftsmanship. Visitors can enjoy the fruits of their labor in the modern Tasting Room, where they can sample Rosehall Run's critically acclaimed wines.

Recognizing and honoring the land's history, Rosehall Run Winery acknowledges and respects its location on the traditional territory of the Haudenosaunee, Anishanabewaki, Wendake-Nionwentsio, and Mississauga peoples
