Cornerstone Estate Winery

Cornerstone Estate Winery grows grapes at Lincoln, in the Niagara Peninsula appellation. It dates its founding to 2002.

Where it sits

Cornerstone Estate Winery is at Lincoln, 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 Cabernet Franc, Sauvignon Blanc, Chardonnay, Merlot, Gewurztraminer, Pinot Gris and Vidal.

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.
