Marynissen Estates Winery

Marynissen Estates Winery grows grapes at Niagara-on-the-Lake, in the Four Mile Creek sub-appellation of Niagara Peninsula. It dates its founding to 1990.

Where it sits

Marynissen Estates Winery is at Niagara-on-the-Lake, and its fruit falls inside Four Mile Creek, one of the sub-appellations nested within Niagara Peninsula. A sub-appellation is the narrower claim: a wine may carry it or the wider appellation name, and the boundaries are set in regulation rather than by the winery. The regions page covers how those lines are drawn.

What it grows

The winery works with Chardonnay, Riesling, Gewurztraminer, Merlot, Gamay Noir and Cabernet Sauvignon.

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.
