Alderlea Vineyards

Alderlea Vineyards grows grapes at Duncan, in the Cowichan Valley sub-appellation of British Columbia.

Where it sits

Alderlea Vineyards is at Duncan, and its fruit falls inside Cowichan Valley, nested within Vancouver Island, one of the recognised growing areas of British Columbia. What a geographic claim means on a label differs by province — the Canadian wineries page sets out how.

What it grows

The winery works with Pinot Gris, Sauvignon Blanc, Pinot Noir, Marechal Foch, Merlot and Bacchus.

Where a grape has a page here, it covers how that variety behaves in Canadian conditions: the heat it needs to ripen, the Brix it reaches, and where it is planted.
