King's Court Estate Winery
King's Court Estate Winery grows grapes at St. Catharines, in the Niagara Peninsula appellation.
Where it sits
King's Court Estate Winery is at St. Catharines, inside Niagara Peninsula — one of the three appellations of origin recognised under Ontario's VQA system. What that claim means on a label, and how the boundary is defined in regulation, is set out on the regions page.
What it grows
The winery works with Riesling, Baco Noir, Sauvignon Blanc, Pinot Noir, Vidal, Cabernet Franc and Gewürztraminer.
Each of those has a page here on how it behaves in Ontario: the heat it needs to ripen, the Brix it reaches at harvest, and which parts of the province actually plant it.
Vineyard area: "King's Court Estate Winery cultivates 30 acres of grapes".
